Sumbawa

Whale sharks in Saleh Bay, empty surf at Lakey Peak, and an island most travelers skip.

Why go

Most travellers fly straight over Sumbawa, which is exactly why it works. Mornings on Saleh Bay mean swimming alongside whale sharks with no other boats in sight; the south coast serves consistent, uncrowded barrels.

Best for

Wildlife travellers who want the whale-shark encounter without the crowds, and surfers chasing consistent waves with an empty line-up.

Planning note

The whale sharks are most reliable in the early morning; base yourself near Saleh Bay the night before rather than day-tripping.

Sumbawa is the long, dry island between Lombok and Flores that almost everyone crosses without stopping. Flights skip it, the ferry crowd drives straight through, and the result is an island the size of Bali and Lombok combined with a fraction of their visitors. What it holds is worth the detour: a bay where whale sharks gather under fishing platforms, a volcanic island with a saltwater crater lake, and some of the most consistent surf in Indonesia.

It is not an easy island to travel casually. Distances are long, the road along the north coast takes most of a day end to end, and outside Sumbawa Besar and the surf camps there is little tourist infrastructure. Most people see it one of two ways: as a surf trip to the south coast, or from the deck of a boat running between Lombok and Flores, which is how the whale sharks and Satonda are usually reached.

Guides

Things to do at Sumbawa

Swim with whale sharks in Teluk Saleh

Fishermen anchor lit platforms called bagan in this bay on the north coast to draw baitfish, and whale sharks learned to come for the same fish. They arrive before dawn while the lamps are still burning. You go out by tender at first light and snorkel with them from the surface. They are wild animals, so nothing is guaranteed.

Walk up to the crater lake on Satonda

A volcanic island off the north coast with a saltwater lake in the middle of it, a few minutes' climb from the beach. The water is more saline than the sea around it. Most boats running the Lombok to Flores route stop here, and almost nothing else does.

See the waterfall on Moyo Island

Mata Jitu falls sits inland on Moyo, a nature reserve island north of Sumbawa Besar. Reached by road and boat it is a two-hour trip each way; reached from the water on a passing boat you arrive with the place largely to yourself.

Surf the south coast

Lakey Peak near Hu'u is the best known, with several reef breaks within paddling distance and a season running roughly April to October. Further west, Maluk and Sekongkang have long right-handers and far fewer people. This is what most foreign visitors actually come for.

Stand on the rim of Tambora

The 1815 eruption was the largest in recorded history and it cooled the entire planet the following year. The caldera is six kilometres across. The climb is a serious two- to three-day trek from the northern villages and needs a guide, not a day trip.

Visit the sultan's palace in Sumbawa Besar

Dalam Loka is a wooden stilt palace from the 1880s in the middle of the island's main town. It takes half an hour to see and is the clearest surviving piece of the Sumbawa sultanate, which is a different cultural world from the Hindu islands to the west.

Good to know

Sumbawa FAQs

Will I definitely see whale sharks at Teluk Saleh?+

No, and be wary of anyone who promises it. They are wild animals feeding around working fishing platforms, not a managed attraction. What a good operator controls is being in the right bay at first light while the lamps are still on, which is when they are there. Sightings are common in season but never guaranteed.

Is Sumbawa worth stopping for, or should I pass through?+

If you surf, it is a destination in its own right. If you do not, the honest answer is that the north coast highlights, whale sharks, Satonda and Moyo, are best reached from a boat already crossing between Lombok and Flores. Driving the island to reach them costs two days you could spend in Komodo.

How rough is the crossing between Lombok and Sumbawa?+

The Alas Strait between Lombok and Sumbawa and the Sape Strait between Sumbawa and Flores are both genuinely open water and can be lively. Bring something for motion sickness even if you do not normally need it. Conditions are calmest from April to October.

Is it a conservative island?+

More so than Bali or Lombok. Sumbawa is strongly Muslim outside the surf enclaves, and modest dress away from the beach is both expected and appreciated. Alcohol is not widely sold beyond the surf camps and larger hotels.
