Why Visit Koh Lanta?

Koh Lanta is the one island in the Krabi group that does not perform for you. There is no Maya Bay here, no cliff you have to photograph, no boat queue. What there is instead is a long, quiet island with a road running down its west coast past one beach after another, each with a slightly different character, and a national park at the southern tip that almost nobody bothers to drive to.

That difference matters more than it sounds. Koh Phi Phi and Railay have no roads at all, which is romantic until you want to leave your beach. Koh Lanta has 30 kilometres of tarmac, which means you can see the whole island in a day on two wheels, eat somewhere different every night, and choose your beach rather than being delivered to it.

It is also the serious diving base of the Andaman coast. Hin Daeng and Hin Muang — the two best deep sites in Thailand, where manta rays and whale sharks turn up — are day-trip distance from here and from nowhere else. If you dive, that single fact settles where you sleep.

Koh Lanta at a Glance

• Where: Krabi Province, southern Thailand, on the Andaman coast, south of Koh Phi Phi
• Which island: “Koh Lanta” means Koh Lanta Yai, the big southern island where everything is. Koh Lanta Noi to the north is the one you cross to get there
• Size: roughly 30 km long — about an hour end to end by scooter
• Access: by road plus a car ferry from the mainland, or by ferry from Krabi, Phuket and Koh Phi Phi
• 🔴 The bridge: Lanta Noi to Lanta Yai has been bridged since 2016. The mainland crossing is still a car ferry — the bridge there is funded but not built
• Beaches, north to south: Klong Dao, Phra Ae (Long Beach), Klong Khong, Klong Nin, Kantiang Bay, Bamboo Bay
• National park fee: 200 THB adult, 100 THB child, 08:30–16:30
• Famous for: long empty beaches, Mu Ko Lanta National Park, the Old Town stilt houses, and world-class diving
• Best time to visit: November to April. Diving peaks February to May
• ⚠️ Low season: some hotels and most beach bars close entirely from May to October
• Getting around: scooter, roughly 200–300 THB a day. This is the one Krabi island where you drive

One Night on Koh Lanta, and Why That Was a Mistake

I came to Koh Lanta on 24 February 2025, arriving in the late afternoon after a morning boat tour around Phi Phi Leh, and left again the following afternoon. One night. I want to be straight about that, because it is exactly the wrong way to do this island and I understood why within about two hours of arriving.

The first thing that happens on Koh Lanta is that nothing happens. After Phi Phi — the pier, the alleys, the boats, the music — the west coast at six in the evening is a road, some trees, a long grey beach and a few bars with bean bags out on the sand. I got around that first evening in a sidecar tuk-tuk, the motorbike-with-a-cabin-bolted-on that serves as a taxi here, which tells you most of what you need to know about the pace of the place.

The next morning I went south, and that is where the island actually is. The road climbs and drops through jungle, the beaches get smaller and emptier, and at the very bottom you reach Mu Ko Lanta National Park at Laem Tanod — a headland with a lighthouse, two beaches meeting at a point, monkeys in the trees and almost nobody there. I was at the lighthouse just before noon and the place was practically mine.

Then I left. A friend had driven down from Koh Samui with his car to collect me for the trip up to Ao Nang, and by three in the afternoon we were on the car ferry watching Lanta go backwards.

What I would do differently: three nights minimum, and pick a beach in the middle of the island rather than at either end. One night gives you an evening and a morning, and Koh Lanta does not reveal anything in that time — its whole appeal is the accumulation of quiet days. Everything below is written with that in mind.

The Beaches of Koh Lanta, North to South

The west coast is a chain of beaches strung along one road, and they get quieter, rockier and more dramatic the further south you go. Choosing between them is the main decision you make on this island.

Klong Dao — the family beach

The first beach south of Saladan pier: a wide, flat, gently shelving crescent with calm water, which makes it the obvious choice with small children. It is also the closest to the pier and the shops, so it is the most convenient and the least wild. If you want to be able to walk to a pharmacy, stay here.

Phra Ae, or Long Beach — the busy one

Several kilometres of sand and the island’s densest concentration of restaurants, bars and dive shops. This is Koh Lanta’s centre of gravity and where most first-timers end up, reasonably enough — you can walk to dinner. Swimming is good at high tide; at low tide the water retreats a long way out.

Klong Khong — the bohemian one

Wooden bungalows, hammocks, fire shows, reggae. Klong Khong has kept more of old Lanta than anywhere else on the island and it is the cheapest place to stay. The catch is real and worth knowing before you book: at low tide the beach becomes a field of rock and coral rubble and swimming is essentially off. People who love Klong Khong come for the atmosphere and treat the sea as a bonus.

Klong Nin — the sweet spot

Mid-island, a proper swimming beach with soft sand, a small village behind it with enough restaurants to keep you fed for a week, and far fewer people than Long Beach. If you asked me to pick one beach on Koh Lanta without knowing anything else about you, it would be this one.

Kantiang Bay and Bamboo Bay — the dramatic south

Down where the road starts to climb, the beaches shrink into steep-sided bays with jungle running down to the sand. Kantiang is the prettiest bay on the island and the most upmarket. Bamboo Bay, further south again, is smaller and quieter still. The trade-off is distance: you are 40 minutes from Saladan and you will be driving to almost everything.

Mu Ko Lanta National Park and the Laem Tanod Lighthouse

The southern tip of Koh Lanta Yai is a national park, and it is the best thing on the island. The drive down is half the point — the road narrows and climbs through jungle with real drops on one side — and at the end you pay 200 THB for adults and 100 THB for children and walk out onto a headland where two beaches meet at a point below a white lighthouse. The park is open 08:30 to 16:30.

The lighthouse, and what the sign on site says

Most guides mention the lighthouse and stop there. There is an interpretive panel standing beside it, and it is worth reading, so here is what it says — attributed to the sign itself, because I photographed it and could find these dates nowhere else.

The original lighthouse was built in 1927 and given its name by King Prajadhipok. It eventually became too damaged to repair, so the government built a replacement nearby, which opened on 23 March 1971. It ran on acetylene gas lamps until 29 March 1990, when it was converted to solar power. The light itself did not change: three white flashes in groups, every fifteen seconds, visible from twelve miles out.

That last detail is independently confirmed in international lighthouse records, which list the tower as roughly 15 metres tall with the same three-flash characteristic. The name is spelled inconsistently even on its own sign — Pachchotiwachirapha in the heading, Phatchotiwachirapha in the body — and the Thai spelling romanises most often as Patchotiwachirapha. Everyone on the island simply calls it the Laem Tanod lighthouse. You cannot go inside the tower.

The nature trail and the monkeys

A circular nature trail of about 1.7 kilometres runs from the visitor centre back to the road, rated moderate, through forest with viewpoints out over the sea. There are macaques around the headland and the picnic area, and the usual rules apply: no visible food, no feeding, no getting between an adult and an infant.

Note that the park’s outlying islands — Koh Rok in particular — close seasonally, generally from mid-May to mid or late October ⚠️ (sources disagree on the exact end date). The Laem Tanod headland itself stays open year-round.

Koh Lanta Old Town

On the east coast, away from every beach, sits Sri Raya — Koh Lanta Old Town. Before the west-coast road existed this was the island’s port and its centre, and it still looks it: a single street of wooden shophouses built on stilts out over the water, part Chinese, part Muslim, part Chao Le, now mostly cafés, craft shops and small guesthouses.

Walk to the end of the street and you reach the old wooden jetty, lined with seafood restaurants sitting on posts above the sea. It is the best place on the island for a slow lunch and it is where the sunset light does something the west coast cannot, because you are looking back at the mainland karsts. There is a small community museum, and a street market at weekends ⚠️ (hours are single-sourced — check locally).

The Chao Le, the sea-nomad communities of the Andaman, have lived on Koh Lanta for generations and still do. Their presence here is residential and ordinary rather than a visitor attraction, and it is best treated that way — this is a place where people live, not a site with a ticket.

Diving from Koh Lanta

This is the strongest argument for Koh Lanta over anywhere else in Krabi, and it is not close.

Hin Daeng and Hin Muang

Two submerged pinnacles about 55 kilometres south of the island, 60 to 75 minutes by speedboat. Hin Daeng — “red rock” — is named for its soft coral; Hin Muang, “purple rock”, is a wall that drops past 60 metres. They are among the very best dives in Thailand and they are not reachable as a day trip from Koh Phi Phi or Phuket. From Koh Lanta they are.

Manta rays are most common from November to April, whale sharks from February to May. Neither is guaranteed and anyone who tells you otherwise is selling something. These are advanced sites — deep, exposed and often with current.

Koh Haa and the closer sites

Koh Haa is a cluster of five small islands closer to Lanta, with caverns, a famous chimney swim-through, excellent visibility and a lot of macro life — nudibranchs, ghost pipefish, harlequin shrimp. It is more forgiving than Hin Daeng and many people rate it just as highly. Koh Bida, up towards Phi Phi, adds leopard sharks, turtles and seahorses.

Season and prices

Most Koh Lanta dive shops run from around mid-October to mid-May and shut for the monsoon — this is a real constraint, not a soft preference. Expect roughly 4,200–4,700 THB for a two-dive day by speedboat, with a third dive adding around 1,000 THB, plus a marine park fee of about 600 THB that is usually excluded from the advertised price. Ask whether it is included before you compare quotes.

⚠️ One point where operators contradict each other: some state the marine park closes to diving from 1 July to 31 August, others simply shift their itineraries to Koh Haa and Phi Phi over the summer. If you are planning a summer trip built around Hin Daeng, confirm directly with a shop before booking flights.

The Four Islands Tour and the Emerald Cave

Koh Lanta’s signature day trip runs south into Trang province rather than north into Krabi, which is why it feels different from every other tour on this coast. The standard circuit takes in Koh Chuek, Koh Muk, Koh Ngai and Koh Kradan, with snorkelling stops and lunch, over seven to eight hours.

The centrepiece is the Emerald Cave — Tham Morakot — on Koh Muk. You put on a life jacket, follow a guide with a headlamp, and swim about 80 metres through a dark limestone tunnel in single file. It is genuinely dark and genuinely narrow, and then it opens into a hidden beach enclosed by cliffs on all sides with a circle of sky above. If you are claustrophobic, this is the one to sit out; if you are not, it is the best thing you will do in Krabi.

Shared tours run roughly 1,000–1,300 THB per person by longtail or speedboat. You can compare a longtail four-islands and Emerald Cave day, the faster speedboat version including Koh Kradan, or a snorkelling-focused longtail trip.

Other Things to Do on Koh Lanta

Ride the length of the island

The single best day on Koh Lanta costs the price of a tank of petrol: take the west coast road south to the national park, cut across to the Old Town, and come back up the east side. Roughly 70 kilometres round trip, and you will see every beach on the island.

Tham Khao Mai Kaew caves

Inland, a genuinely rough guided cave walk — mud, squeezes, a torch and a local guide, ending at an underground pool. Not a boardwalk-and-coloured-lights cave. Wear clothes you do not mind destroying.

Klong Chak waterfall

A jungle walk to a small waterfall and a bat cave. Worth doing in the wet months and largely pointless at the end of the dry season, when there is not much water.

Where to Stay on Koh Lanta

Because the island is long and the beaches genuinely differ, this decision matters more here than on Phi Phi or Railay. The short version: Klong Dao for families and convenience, Long Beach for restaurants and walkability, Klong Khong for cheap and bohemian, Klong Nin for the best all-round balance, Kantiang for scenery and comfort.

🔴 One booking trap specific to this island. Plenty of Koh Lanta hotels close completely from around May to October. Twin Lotus even writes its season into its Booking listing. If a property shows no availability at all for low-season dates, that is usually a seasonal closure rather than a sell-out — and the beach bars shut then too, which changes the island considerably.

Klong Dao — closest to the pier

• Avani Plus Koh Lanta Krabi Resort — the five-star option at the north end, formerly Crown Lanta.
• Golden Bay Cottage – SHA Extra Plus — straightforward beachfront on the calmest swimming sand on the island.
• Royal Lanta Resort & Spa — bungalows and pools, a short walk from Saladan.
• Costa Lanta – Adult Only — concrete-and-teak design pavilions, adults only, unlike anything else here.
• Twin Lotus Resort and Spa – SHA Plus – Adult Only — ⚠️ open November to April only.

Phra Ae, Long Beach — restaurants on your doorstep

• Layana Resort & Spa – Adult Only — consistently the highest-scored hotel on Koh Lanta. Adults only.
• Nakara Long Beach Resort – SHA Extra Plus — good mid-range value right on the strip.
• SriLanta Resort and Spa — hillside and beachfront rooms with a spa.
• Phra Ae Apartments — self-catering, useful for longer stays.

Klong Khong — cheap and bohemian

• Lanta Emerald Bungalow — classic wooden bungalows on the sand.
• Khum Laanta Resort – SHA Extra Plus — a step up in comfort while staying on this beach.

Remember the tide here: at low water this beach is rock, not sand.

Klong Nin — the balanced choice

• Rawi Warin Resort And Spa – SHA Extra Plus — the big resort of the mid-island, terraced up the hillside.
• Lanta Klong Nin Beach Resort — simple, a few steps from the sand, good value.
• Lanta IL Mare Beach Resort — well reviewed and quiet.
• Lanta Casa Blanca — one of the newer places on this stretch.

Kantiang Bay — the scenic south

• Pimalai Resort & Spa — the best-known hotel on Koh Lanta, spread across a hillside above its own beach.
• Baan KanTiang See Villas – SHA Extra Plus — two-bedroom villas with private pools, good for families or two couples.
• Kantiang Bay View Resort — the budget option in an otherwise expensive bay.

Eating and Nightlife

Koh Lanta eats better than its size suggests, and it is cheaper than Phi Phi. Saladan, at the northern tip, has seafood restaurants over the water by the pier and the island’s best local markets. Long Beach has the densest run of restaurants, from beach shacks to Italian. Klong Nin village punches above its weight. And the Old Town jetty restaurants are the most atmospheric meal on the island.

Nightlife is beach bars, bean bags, fire shows and reggae — Klong Khong is the centre of it, Long Beach the busiest. Nobody comes to Koh Lanta for a club, which is precisely the point of coming to Koh Lanta. Note that most beach bars shut for the monsoon.

Getting to Koh Lanta

🔴 The bridge that is not built yet

This trips up a lot of visitors, because plenty of older articles get it wrong. There are two crossings between the mainland and Koh Lanta Yai, and only one of them is a bridge:

• Koh Lanta Noi → Koh Lanta Yai: the Siri Lanta Bridge, open since June 2016. You drive straight over.
• Mainland → Koh Lanta Noi: still a car ferry, running roughly 06:00 to 22:00, about 30 minutes, and liable to delay in rough weather.

A bridge for the mainland crossing has been planned for years and articles from 2020 predicted it would open in 2025. It did not. Financing was approved by the Thai cabinet in July 2026 for a 2.24 km bridge costing around 1.85 billion baht, with construction still ahead of it. Plan for the ferry.

By minivan and ferry

The usual route is a combined minivan-and-ferry ticket from Krabi town, Krabi airport or Ao Nang. In high season passenger ferries also run direct from Koh Phi Phi and Phuket. You can compare operators, times and prices for Krabi to Koh Lanta, Krabi Airport to Koh Lanta, Koh Lanta to Koh Phi Phi and Koh Lanta to Phuket on 12Go. Out of season the direct island ferries thin out and everything reverts to the road.

Getting Around Koh Lanta

Unlike Phi Phi and Railay, Koh Lanta has roads — and using them is the whole point. A scooter costs roughly 200–300 THB a day and turns the island from a beach into a place. The west coast road is decent tarmac for most of its length; south of Kantiang it becomes steep and winding, and that stretch deserves respect, particularly in the wet.

If you would rather have four wheels — worth considering with children, luggage or in the monsoon — you can compare car hire prices at Krabi airport on DiscoverCars and drive down, ferry included.

Without your own transport there are sidecar tuk-tuks — a motorbike with a passenger cabin welded to the side, the local taxi. They work fine for short hops between neighbouring beaches and become expensive quickly over distance. Agree the fare before you get in.

Best Time to Visit Koh Lanta

November to April

Dry, calm and fully open. Everything runs, the ferries are reliable and the diving is at its best — mantas from November, whale sharks from February. December to February is the peak in both crowds and price. I was there at the end of February and it was ideal.

⚠️ May to October — the island genuinely changes

This is not the usual green-season caveat. On Koh Lanta the low season means some hotels close outright, most dive shops shut, beach bars come down and direct island ferries stop. It has improved — more of the bigger resorts now stay open year-round, and August sees a bump of European visitors — but you should check that your specific hotel and dive shop are actually operating on your dates rather than assuming. The upside is real too: half-price rooms and beaches with nobody on them.

Practical Tips

Tides

Koh Lanta has a big tidal range and it changes the beaches completely. Klong Khong turns to rock at low water; Long Beach retreats a long way out. Check the day’s tide before planning an afternoon swim.

Money and supplies

ATMs are in Saladan and the main beach villages, and Thai machines charge a fixed foreign-card fee of around 220 THB per withdrawal. Carry cash for the national park, tuk-tuks and small restaurants. Pharmacies are in Saladan; the island has a small hospital, but anything serious means the mainland.

Riding safely

Wear the helmet. Check your travel insurance actually covers you on a motorbike — many policies require a licence valid for the category, and an International Driving Permit alongside your home licence. Photograph the scooter from all sides before you ride off, and never hand over your passport as a deposit.

Entry formalities

All non-Thai nationals must file the free Thailand Digital Arrival Card online within three days before arriving. File it only on the official government portal — third-party sites charge for what is free.

Is Koh Lanta Right for You?

Koh Lanta is the easiest island in Krabi to love and the easiest to be disappointed by, and which one happens depends almost entirely on what you arrived expecting.

Come here if you want a week rather than a weekend, you would rather have a scooter and a road than a boat timetable, you dive, or you are travelling with children who need a beach they can actually swim off. Koh Lanta is also the only island in this group where a family can rent a car, drive to dinner and put the kids to bed at a normal hour.

Do not come here if you have two nights and want the postcard. The famous limestone scenery of Krabi is mostly north of here — Koh Lanta’s coast is long and low rather than vertical. For cliffs and lagoons in a short stay, Railay and Phi Phi do it better, and I would say so even having enjoyed Lanta more.

The mistake I made was treating it as a stop between two other places. Koh Lanta is not a stop. It is somewhere you stay put.

Frequently Asked Questions About Koh Lanta

Where is Koh Lanta?

Koh Lanta is in Krabi Province on Thailand’s Andaman coast, south of Koh Phi Phi. “Koh Lanta” in practice means Koh Lanta Yai, the larger southern island where all the beaches and villages are; Koh Lanta Noi to the north is the island you cross on the way in.

Is there a bridge to Koh Lanta?

Partly. The Siri Lanta Bridge has linked Koh Lanta Noi to Koh Lanta Yai since 2016, but the mainland crossing to Koh Lanta Noi is still a car ferry, running about 06:00 to 22:00 and taking around 30 minutes. A mainland bridge was approved for financing in July 2026 but has not been built.

How do you get to Koh Lanta?

Most people take a combined minivan-and-ferry ticket from Krabi town, Krabi airport or Ao Nang. In high season passenger ferries also run direct from Koh Phi Phi and Phuket; out of season those thin out and everything goes by road.

Which is the best beach on Koh Lanta?

Klong Nin is the best all-round choice — good swimming, a village behind it and far fewer people than Long Beach. Klong Dao suits families, Phra Ae has the most restaurants, Klong Khong is cheapest and most bohemian, and Kantiang Bay is the prettiest and most upmarket.

How many days do you need on Koh Lanta?

At least three, and ideally more. Koh Lanta has no single unmissable sight and rewards a slow stay rather than a quick visit. I gave it one night and that was too little to judge the island fairly.

How much is Mu Ko Lanta National Park?

200 THB for foreign adults and 100 THB for children, open 08:30 to 16:30. It covers the Laem Tanod headland at the southern tip, with the lighthouse, two beaches and a 1.7 km nature trail.

Can you dive Hin Daeng and Hin Muang from Koh Lanta?

Yes — they are about 55 km south, 60 to 75 minutes by speedboat, and Koh Lanta is the only realistic day-trip base for them. Manta rays are most common November to April, whale sharks February to May. Both are advanced sites, deep and often with current.

How much does diving cost on Koh Lanta?

Roughly 4,200–4,700 THB for a two-dive day by speedboat, with a third dive adding about 1,000 THB, plus a marine park fee of around 600 THB that is usually not included in the advertised price. Most shops operate mid-October to mid-May only.

What is the Emerald Cave?

Tham Morakot, on Koh Muk, reached on the Four Islands day trip from Koh Lanta. You swim about 80 metres through a dark limestone tunnel in a life jacket behind a guide with a headlamp, and come out on a hidden beach ringed by cliffs. Skip it if you are claustrophobic.

Do hotels close on Koh Lanta in low season?

Some do, entirely, from roughly May to October, along with most dive shops and beach bars. More of the larger resorts now stay open year-round than used to, but if a hotel shows zero availability across low-season dates that is usually a seasonal closure rather than a sell-out.

Do you need a scooter on Koh Lanta?

Not strictly, but it transforms the visit. The island is about 30 km long with the beaches strung along one road, and rental runs roughly 200–300 THB a day. Sidecar tuk-tuks work for short hops but get expensive over distance. The road south of Kantiang is steep and winding.

Is Koh Lanta better than Koh Phi Phi?

They are not really competing. Koh Phi Phi has the spectacular limestone scenery and the nightlife; Koh Lanta has length, quiet, roads and the best diving on the coast. Choose Phi Phi for a short scenic trip, Koh Lanta for a longer, slower one — or do both, they are two hours apart in high season.
