The Forgotten Islands East of Bali: Sumba, Sumbawa and Beyond

The island chain running east from Bali changes character with distance. Lombok is greener and quieter. Sumbawa is drier, wilder and barely touched by tourism. Sumba has a living megalithic culture that predates the region's religions and survives alongside them. And beyond them the islands get smaller, drier and more remote until the ferry schedules stop mattering because there are no ferries. All of this sits within a short flight of one of the busiest tourist islands on earth, and almost nobody goes.

How the chain changes as you travel east

The dominant pattern is rainfall. Bali and Lombok sit in a wetter zone with intensive rice agriculture. As you move east, the monsoon pattern shifts, the dry season gets longer, and the landscape changes from terraced green to savanna grassland with palms and lontar. By Sumba and the islands further east, the countryside looks more like dry Australia than like the tropical Bali of the brochures.

Culture follows the same gradient. Bali is Hindu. Lombok has a substantial Sasak Muslim population with a distinct language and set of traditions. Sumbawa is Muslim with its own language and a strong horse and buffalo culture. Sumba is a mix, and it is where the older ancestral traditions remain most visibly alive.

This is what makes the chain interesting. Travelling east is not more of the same island; it is a genuinely different place every few hours of travel, in landscape, religion, language and food.

Lombok: closer than you think

Lombok is the easy first step and the one most people skip on the way somewhere else. Its interior holds rice terraces, waterfalls and the slopes of a large volcano that is a serious multi-day trek in its own right. The southern coast has a sequence of beaches that are excellent and, away from a handful of developed pockets, remarkably empty.

The ascent of the volcano is the standout. It is a two-day climb with a crater lake at the summit, and it is physically demanding rather than technical. Most people do it as an organised trek with a guide and porters, departing in the small hours to reach the rim for sunrise.

Lombok also works as a base. Regular boats and flights run onward to Sumbawa, and the infrastructure is good enough that you can sort out onward travel, cash and supplies without difficulty before heading somewhere with less of all three.

Sumbawa: the wild one

Sumbawa is large, sparsely populated, and has almost no tourism infrastructure beyond a handful of surf camps. The coastline is extraordinary — long empty bays, hills dropping straight into the sea, and beaches where you will genuinely see no one all day.

Getting around is the constraint. Roads are slow, distances are long, and public transport is infrequent. Motorbike is the practical option for anyone comfortable riding, and hiring a driver for several days is the alternative. Either way, build in more travel time than maps suggest, because road conditions vary enormously.

What Sumbawa offers is the experience that people imagine Bali was forty years ago: villages where arrivals are genuinely novel, agriculture that dominates the economy, and a landscape with no accommodation on it. That comes with the corresponding absence of services, so carry cash, fuel up whenever you can, and do not plan on finding a pharmacy or an ATM at short notice.

The surfing is world-class and well known within that community, which means the few developed spots are surf camps. Outside them, you are on your own in the best sense.

Sumba: the megalithic culture

Sumba is the most culturally distinctive island in the chain and the one that most rewards slowing down. It has a strong tradition of megalithic tomb construction — large carved stone graves in and around villages, some still being made. It has a distinctive clan and village architecture, with tall peaked roofs that serve both practical and ceremonial purposes. And it has a textile tradition, particularly ikat weaving, that is among the finest in the region.

The ancestral belief system, sometimes described by the shorthand of its ritual practice, coexists with Christianity and Islam on the island. Ceremonies, including large funerary events, are part of the living calendar rather than performances for visitors. If you are invited to observe one, the correct response is to accept with genuine respect, dress modestly, bring a small gift, and follow the lead of whoever invited you.

The west of the island is wetter, greener and more traditional; the east is drier and has more savanna landscape. Both are worth time. Accommodation exists at the upper end and a little in the middle, but it is limited, and booking ahead during ceremony season is essential.

Getting there: flights, ferries and realistic timings

Flying is the practical way east. Regular services connect Bali to Lombok and to the main airports on Sumbawa and Sumba, and the flights are short. Ferries run between the larger islands and are cheaper but considerably slower and more subject to cancellation in bad weather.

The mistake people make is trying to chain too many islands on a fixed schedule. A two-week trip that tries to cover Lombok, Sumbawa and Sumba ends up being a trip about transport. Two islands done properly is better than four done badly, and the ground transport on each island is slower than it looks on a map.

Book flights ahead for the smaller routes, because capacity is limited and schedules change seasonally. For ferries, check the current schedule locally rather than relying on anything you read in advance — departure times move, and boats are occasionally cancelled with no notice at all.

Practical realities: cash, health, connectivity

Cash is essential. ATMs exist in the main towns on each island and become scarce or unreliable away from them. Withdraw more than you think you need whenever you pass a working machine, and carry small denominations, because change is a perennial problem in rural areas.

Medical facilities are basic outside the main towns. Bring a proper first aid kit, any regular medication in sufficient quantity, and know that evacuation to Bali is the realistic plan for anything serious. This is a strong argument for travel insurance that covers medical evacuation rather than just treatment.

Connectivity is patchy. Mobile data works in towns and along main roads and drops out in rural and coastal areas. Download offline maps for each island before you travel, and do not rely on being able to look something up at the moment you need it.

Malaria risk exists in parts of eastern Indonesia and varies by island and season. Check current health guidance for the specific areas you will visit before you travel and follow the recommendation rather than a general impression about the region.

Respect and etiquette

These are conservative, largely Muslim and traditionally religious communities. Dress modestly away from the beach — covered shoulders and knees for both men and women is a reasonable default, and it is genuinely appreciated rather than merely tolerated. Ask before photographing people, and accept no as an answer.

Friday is the main prayer day, and in observant villages it shapes the rhythm of the day. During the fasting month, eating and drinking in public during daylight is discourteous; plan around it and eat where you are not visible.

Modesty in behaviour matters as much as in dress. Public drunkenness, loud behaviour and public displays of affection read very differently here than in Bali's tourist areas, and the difference in how you are received is noticeable.

Food and daily life on the eastern islands

The food changes with the rainfall, and it is one of the clearest signals that you have left Bali behind. Rice dominates in wetter Lombok; further east, corn, cassava, sago and sorghum take over as the staples, and seafood becomes the reliable protein along the coast.

On Sumba, look for the local style of finely chopped meat or fish with lime and chilli, and for the variety of corn-based dishes that reflect the drier agriculture. On Sumbawa, the food is plainer and often excellent — grilled fish, simple vegetable dishes, and rice where it is grown. Everywhere, the small roadside food stalls are where the best meals are, and they close early.

Practicalities follow from the same pattern. Eat where the food is being cooked fresh and where turnover is high. Drink bottled or treated water and avoid ice of uncertain origin. On longer road journeys, carry water and snacks, because the gaps between places that sell anything can be substantial and the heat makes those gaps feel longer.

Friday prayers and the fasting month shape opening hours in observant areas, and in small villages there may be very little available for part of the day. Planning around that is basic courtesy as well as basic logistics.

Conclusion

The islands east of Bali are a different country in every way that matters: drier, quieter, more traditional and far less prepared for visitors. Start on Lombok for the volcano and the southern beaches. Go to Sumbawa if you want empty coastline and are willing to work for it. Go to Sumba for the megalithic culture and the ikat, and go slowly. Fly rather than ferry where the choice exists, carry cash, sort out medical evacuation cover, download offline maps, and dress and behave for conservative communities rather than for the beach. Two islands done properly will stay with you far longer than a rushed circuit of four.
