Sumbawa Travel Guide 2026: Whale Sharks, Surf & Beaches
By Blaise Jaeger · Updated June 4, 2026
Sumbawa is one of Indonesia’s last truly untouched islands. Located in West Nusa Tenggara, Sumbawa remains one of the country’s most underrated islands, offering some of the best things to do in eastern Indonesia — from whale shark tours to remote surfing beaches.
Far less developed than Bali or Lombok, Sumbawa is ideal for travelers seeking raw landscapes, authentic villages, and unforgettable wildlife experiences. During each of my visits to Sumbawa, what struck me most was how empty the beaches felt — especially after traveling through Bali and Lombok. Whale shark encounters in Saleh Bay remain one of the most authentic marine experiences I’ve had in Indonesia. Like neighboring Sumba, Sumbawa has largely remained off the mass-tourism radar, which is exactly why it remains so rewarding for independent travelers.
This complete 2026 Sumbawa travel guide covers the best things to do, how to get there, where to stay, when to visit, suggested itineraries, and how to swim with whale sharks responsibly in Saleh Bay.

What Keeps Drawing Me Back to Sumbawa
I’ve made the trip from Bali to Sumbawa three times now, each visit lasting four to seven days. Sumbawa is just east of Lombok — close enough to be an easy escape from Bali’s crowds, yet wild enough to feel like an entirely different country. After three visits, I keep coming back for the same three reasons.
First, swimming with whale sharks in Saleh Bay on the central coast — a wildlife encounter so close, so quiet, and so unhurried that no aquarium experience can compare. Second, diving with manta rays off the west coast, where the cleaning stations are still uncrowded and the visibility is consistently excellent. Third, the surf breaks at Lakey Peak on the east coast — waves I’d rate among the most consistent in Indonesia, with a small but genuine surf town that hasn’t been swallowed by Bali-style development.
This guide reflects what I’ve learned across these visits: which roads are actually passable in rainy season, where to base yourself depending on whether you came to dive, surf, or simply explore, and which local warungs serve the best food without appearing on any travel blog. It’s not a one-trip guide written from a Bali hotel — it’s the Sumbawa I keep returning to, and the one I want you to discover.
Why Visit Sumbawa?
Sumbawa is best known for wild nature, long distances, and experiences that still feel genuinely local. The main reasons to visit are:
- 🐋 Swimming with whale sharks in Saleh Bay
- 🏄 World-class surfing in Lakey Peak & Huu
- 🌋 Mount Tambora volcano
- 🏝️ Remote beaches with almost no crowds
- 🐠 Snorkeling & diving around Moyo Island
If Bali feels too busy and Lombok too developed, Sumbawa still feels raw, authentic, and adventurous — but it also requires more planning, longer transfers, and a bit more flexibility.
Sumbawa vs Lombok: Which Island Is Right for You?
Sumbawa and Lombok are neighboring islands in West Nusa Tenggara, but they offer very different travel experiences. While Lombok has become a popular alternative to Bali, Sumbawa remains one of Indonesia’s least-developed and most authentic destinations.
If you are looking for convenience, tourist infrastructure, and easy access, Lombok is usually the better choice. If you prefer adventure, empty beaches, whale sharks, and a more off-the-beaten-path experience, Sumbawa is hard to beat.
| Lombok | Sumbawa |
|---|---|
| More developed tourism infrastructure | More authentic and less developed |
| Easier transportation and logistics | Longer distances and more adventurous travel |
| More hotels and restaurants | Fewer facilities but a more local atmosphere |
| Popular beaches and the Gili Islands | Remote beaches with very few tourists |
| Easier for first-time visitors to Indonesia | Better suited to independent travelers |
| Mount Rinjani trekking | Whale sharks, Tambora volcano, and world-class surf |
| Higher visitor numbers | Much fewer tourists |
Should You Choose Lombok or Sumbawa?
Choose Lombok if you are looking for a relaxing beach holiday, easy logistics, and a wider range of accommodation options.
Choose Sumbawa if you want to experience a more authentic side of Indonesia, swim with whale sharks in Saleh Bay, surf uncrowded waves, or explore remote beaches far from the main tourist routes.
For many travelers, the ideal solution is to combine both islands. Thanks to regular flights and ferries, it is easy to visit Lombok and Sumbawa during the same trip.
Best Things to Do in Sumbawa
🐋 Swim with Whale Sharks in Saleh Bay
One of the main reasons travelers visit Sumbawa is the opportunity to swim with whale sharks in Saleh Bay. It is one of Indonesia’s most memorable marine wildlife experiences.
Unlike many destinations where sightings are seasonal, whale sharks can be observed here year-round. They are attracted by plankton and traditional fishing platforms known as bagan.
What to Expect
- Early morning departure (around 4–5 am)
- 1-hour boat ride in calm waters
- Snorkeling or diving in shallow conditions
- Whale sharks feeding near the surface
- Excellent visibility (often 15–25 m)
The experience is calm and respectful. These gentle giants can grow up to 12 meters long but are completely harmless.
Best Time to See Whale Sharks
Whale sharks are present all year, but the dry season (May–November) offers:
- Calmer seas
- Better visibility
- Higher chance of multiple sightings
Many local operators also observe stronger activity around the new moon.
This is one of the most accessible and authentic ways to see whale sharks in Indonesia, especially if you choose an operator that keeps distance, limits time in the water, and avoids touching or chasing the animals.

🏄 Surfing in Huu & Lakey Peak
Sumbawa is internationally known for its surf breaks.
Lakey Peak and Lakey Pipe near Huu attract surfers from around the world thanks to consistent reef breaks and powerful waves.
Best for:
- Intermediate to advanced surfers
- Dry season swells (May–October)
The atmosphere is laid-back and far less crowded than Bali.
🌊 Kertasari & West Coast Beaches
Kertasari village
The village of Kertasari, on Sumbawa’s western coast, is a surfer’s paradise. Its consistent waves cater to both beginners and experienced surfers. The tranquil setting and absence of crowds make it even more appealing. Besides surfing, Kertasari is ideal for snorkeling and swimming, thanks to its crystal-clear waters and well-preserved coral reefs. Scuba diving with the Mocean Resort is another highlight, offering opportunities to see manta rays feeding near the small island in Kertasari Bay.
The Beaches South of Taliwang
While part of Sumbawa’s western coastline is industrialized, with power plants and mining operations, there are still some truly stunning beaches to explore—ideal for both relaxation and surfing.
One must-visit spot is Scar Reef Beach, a breathtaking and impressive location renowned for its powerful waves. If you’re unsure where to settle on the beach, do as I did and grab a coffee at Myamo Beach Cottage—a great starting point.
Seaweed farming
Surrounded by lush rice fields and green hills, Kertasari also offers visitors a glimpse into rural life. You can learn about the local seaweed farming process, similar to what is seen in Nusa Lembongan, and savor local specialties like ikan bakar (grilled fish) at small seaside eateries (warungs).
🏝️ Moyo Island
Moyo Island is a peaceful snorkeling and diving destination off Sumbawa’s coast.
Expect:
- Clear turquoise waters
- Healthy coral reefs
- Sea turtle nesting sites
- Eco-lodges and simple accommodation
It’s ideal for travelers wanting a slow island escape.
🌋 Mount Tambora
Mount Tambora is one of Indonesia’s most historically significant volcanoes. Its 1815 eruption changed global climate patterns.
Today, trekking Tambora offers:
- Expansive crater views
- Multi-day hiking routes
- Remote wilderness atmosphere
Best attempted during dry season months.
How to Get to Sumbawa
Reaching Sumbawa is easier than many travelers expect. The island is accessible by both air and ferry from Bali, Lombok, and other parts of Indonesia. If you’re planning a longer trip across the archipelago, you may also find my guides on how to get to Indonesia and how to travel around Indonesia useful. You can also check the official Indonesian tourism portal for broader trip-planning information.
For most travelers, the easiest route is to fly to Sumbawa Besar if your priority is Saleh Bay whale sharks, or to Bima if you are heading to Lakey Peak, Huu, or eastern Sumbawa. If you are combining Lombok and Sumbawa, the ferry from Kayangan to Poto Tano is usually the most flexible option.
By Air
Fly from:
- Bali (Denpasar)
- Jakarta
- Lombok
Airports:
- Sumbawa Besar (west)
- Bima (east)
Flight time from Bali: around 1 hour.
If you are seated near the window on the left side of the plane from Bali, you may be lucky enough to observe the Rinjani volcano and its crater lake up close.
By Ferry
From Lombok, ferries depart from Kayangan port to Poto Tano on Sumbawa. The crossing takes about 1.5 hours and runs hourly throughout the day, with prices around Rp 20,000 (~$1.50) per passenger. You can also book your Lombok–Sumbawa ferry in advance on 12Go if you prefer a hassle-free experience with hotel pickup.
From Flores, ferry connections also operate to Bima or Sape in eastern Sumbawa.
Where to Stay in Sumbawa
West Sumbawa (Kertasari & Taliwang)
- Beachfront guesthouses
- Surf lodges
- Relaxed atmosphere
Whales & Waves in Kertasari offers ocean views and peaceful surroundings.
Sumbawa Besar
Good for:
- Airport access
- Whale shark tours in Saleh Bay
- Overnight stays before Saleh Bay
Hotel Kaloka is conveniently located and organizes whale shark boat trips. If whale sharks are your main reason for visiting Sumbawa, Sumbawa Besar is the simplest base for one or two nights before an early departure to Saleh Bay.
Huu / Lakey Peak
Best for surfers.
Simple surf lodges and beachfront stays dominate the area. I stayed at The Tree House Sumbawa and had a great experience.
Culture & Local Life in Sumbawa
Unlike Hindu Bali, Sumbawa is predominantly Muslim — and that cultural difference is one of the things that gives the island its distinct atmosphere. You’ll hear the call to prayer five times a day across the towns and villages, see modest dress codes (especially in rural areas), and find that alcohol is far less available than in Bali (most warungs don’t serve it; some larger hotels do). It’s not restrictive — Sumbawanese people are warm, curious, and welcoming — but it’s worth dressing respectfully when visiting villages, mosques, or local markets.
The island is split between two main ethnic groups: the Sumbawanese in the west (around Sumbawa Besar and Taliwang) and the Bimanese in the east (around Bima and Dompu). Each has its own language, traditions, and even slightly different cuisine. The most visible cultural treasure of Sumbawa is its horse-riding tradition — the small but tough Sumbawa horse (kuda Sumbawa) has been bred here for centuries, and traditional horseback races still happen during local festivals in towns like Taliwang. If you visit between April and August, ask locals about upcoming pacu kuda (traditional horse races) — they’re chaotic, joyful, and a window into pre-tourism Sumbawa.
For food, Sumbawa cuisine leans on grilled fish, sambal, and rice — simpler and spicier than Balinese cooking. The local specialty everyone mentions is sepat: a sour-spicy fish soup with mango that you’ll find in warungs from Sumbawa Besar to Bima. In coastal villages, ask for ikan bakar (grilled fish) caught the same morning and served with sambal and steamed rice — usually under 50,000 IDR for a complete meal. The food won’t blow your mind like Balinese fine dining, but it’s honest, fresh, and reflects the rhythms of an island where most people still fish, farm, or raise horses.
Best Time to Visit Sumbawa
The best time to visit Sumbawa is during the dry season (May–November).

- Better surf conditions
- Calmer seas for whale shark tours
- Easier road travel
