Brunei in 7 Days on a Budget (With Daily Costs)

Seven days in Brunei, budgeted (and an honest border crossing)

A full week in Brunei alone is more country than the country has to offer. The honest budget plan spends about four days doing Brunei properly, BSB’s mosques, Kampong Ayer, a Temburong rainforest overnight, and the Tutong-Belait oil coast, then crosses the land border into Malaysian Borneo for the back half. Brunei is a small, oil-and-gas-rich Islamic sultanate on the north coast of Borneo, not a district of Malaysia, bordered on every land side by Malaysia’s Sarawak state and split into two pieces by the Limbang district. Costs stay in Brunei dollars (BND) for the first four days; once you cross the border, prices switch to Malaysian ringgit (RM), so budget the two halves separately.

Book these before you go:

How many days do you need in Brunei?

Two to three days cover BSB’s core comfortably; four is the honest ceiling once you add a Temburong overnight and the Tutong-Belait coast without rushing. A full week spent inside Brunei alone is a genuine stretch for what the country offers, which is why this 7-day plan spends its second half in Malaysian Borneo rather than inventing Brunei sights that don’t exist. Its first four days nest the shorter 2-day , 3-day and 4-day plans, extending the same spine rather than replacing it, and a slower version of this same week is the 6-day plan if you would rather stay inside Brunei the whole time.

Day 1: BSB’s mosques and the Royal Regalia Museum

Start at the Omar Ali Saifuddien Mosque, free to enter outside prayer times, its gold dome and marble facade mirrored in an artificial lagoon. Dress modestly (shoulders and knees covered, a head covering for women); robes are loaned free at the entrance if you need one. Budget 45-60 minutes.

Taxi or walk to the Jame’Asr Hassanil Bolkiah Mosque in Gadong, Brunei’s largest, with 29 golden domes, also free and closed to visitors during prayer times. In the afternoon, visit the Royal Regalia Museum on Jalan Sultan, free entry, housing the Sultan’s coronation regalia and state gifts; budget an hour.

Close the day at the Gadong Night Market, where grilled skewers, fried noodles and other street food run a few BND a plate. Try ambuyat if it’s on offer, a sago-starch dish eaten by twirling strands on a fork and dipping them in a savoury sauce, not the “fermented fruit” some old guides claim.

Day 2: Kampong Ayer and a proboscis-monkey river cruise

Spend the morning at Kampong Ayer, the stilt water village on the Brunei River, home to more than 10,000 people today (older figures citing 30,000 are out of date). A one-way water-taxi crossing runs a couple of BND; agree the fare before boarding. Budget 1-2 hours wandering the boardwalks.

Book a Brunei River cruise for late afternoon, when proboscis monkeys are most active along the mangroves; sightings of these long-nosed monkeys, and sometimes crocodiles, are the main draw. A shared boat runs roughly BND 20-40 per person depending on operator and group size, so check current rates before booking. The Istana Nurul Iman, the Sultan’s palace and reportedly the world’s largest residential one, is not open for regular tours, only during the Hari Raya open house, so don’t plan around visiting it. If you have energy left, a walk around Tasek Lama Recreational Park, a forest reserve inside BSB, rounds out the day (check current opening hours locally).

Day 3: crossing to Temburong, overnight in the rainforest

Cross the Sultan Haji Omar Ali Saifuddien Bridge, open since 17 March 2020, for a direct 30-45 minute drive into the Temburong district with no Malaysia transit required. The old route, a speedboat or a checkpoint-heavy drive through Malaysia’s Limbang, is no longer necessary, though some operators still run the scenic speedboat as an experience in itself.

Ulu Temburong National Park is licensed-guide-only; independent entry isn’t permitted. With a full week to spend, this is the plan that turns the usual rushed day trip into an overnight inside or near the park, longboat up narrowing tributaries in the afternoon, a guided rainforest walk before dark, and time to actually rest rather than drive straight back to BSB. An overnight guided package with meals commonly runs somewhere in the BND 150-220 per person range, though tour pricing moves, so confirm current rates and availability before booking. Bring mosquito repellent and shoes that can get wet; watch for snakes on the trails and don’t swim where crocodile warnings are posted.

Day 4: the canopy walkway, then Seria and Jerudong

Spend the morning on the canopy walkway, suspended high above the forest floor, before your guide takes you back across the bridge to BSB. On the way, or after a stop back at your hotel, drive west through Tutong to Belait district. Seria, the country’s original oil town, is home to the Billionth Barrel Monument, built in 1991 to mark Brunei’s billionth barrel of crude oil, produced that July; it’s a free, quick stop rather than a destination in itself.

Round out the day at The Empire Brunei, a former royal guesthouse in Jerudong scaled up into a roughly 520-room resort, worth a look at the lobby even if you’re not staying there, and next door at Jerudong Park, an amusement park still running in 2026 on a variable weekly schedule (check current hours before you plan around it). A rental car or a day tour covers this distance more easily than taxis.

Day 5: crossing into Malaysian Borneo

This is where the honest version of a Brunei week stops pretending Brunei has seven days of sights and admits the obvious: the rest of Borneo is right next door. Cross the land border into Malaysia’s Sarawak state, most practically toward Miri, the nearest Sarawak city, by road transfer or a short flight; check current border-crossing points, opening hours and fares before you travel, since these change and this leg isn’t run by any Brunei-side operator. The moment you cross, prices switch from BND to Malaysian ringgit (RM); Brunei dollars aren’t the local currency here, so change money or use cards once you’re through immigration.

Use the rest of the day to settle in and reset your expectations: Sarawak is a different Malaysian state with its own pace, cuisine and sights, not an extension of Brunei’s itinerary.

Day 6: Gunung Mulu or Kota Kinabalu, your call

From Miri, most travellers either fly on to Gunung Mulu National Park, a UNESCO World Heritage Site in Malaysia (not Brunei) known for its show caves and the Pinnacles limestone spikes, or continue into Sabah toward Kota Kinabalu, the gateway to Mount Kinabalu. Both are genuine multi-day draws in their own right; with one day here, pick whichever leg matches the flights and tour availability you find when you book, and check current fares before committing, since this route isn’t part of the Brunei dossier this plan otherwise draws from.

Either way, this day belongs to Malaysia, not Brunei: different park fees, different guides, different rules. Don’t expect Brunei’s alcohol or dress restrictions to carry over unchanged; Malaysia’s are looser in most tourist areas, though still worth checking locally.

Day 7: last stop, then home

Spend the morning at whichever base you chose, Miri’s town centre and waterfront, or Kota Kinabalu’s markets and seafront, before heading to the airport. Most return routings fly out via Malaysia rather than back through Brunei, so check your outbound leg when you book rather than assuming a return through BWN.

Day Focus Rough daily cost
1 Mosques (free), Royal Regalia Museum (free), Gadong Night Market dinner BND 20-35
2 Kampong Ayer water taxi, proboscis-monkey river cruise BND 40-70
3 Bridge crossing, guided Ulu Temburong rainforest walk, overnight in the park BND 150-220
4 Canopy walkway, Seria/Billionth Barrel Monument drive, Empire Brunei, Jerudong Park BND 90-150
5 Border crossing into Sarawak, Malaysia (currency switches to ringgit) RM 80-150
6 Gunung Mulu caves and the Pinnacles, or Kota Kinabalu and Mount Kinabalu views RM 100-200
7 Final morning, departure RM 40-80

Days 1-4 are in Brunei dollars; days 5-7 are in Malaysian ringgit once you’re across the border. Both cover food, local transport and paid activities; they exclude your hotel room and flights.

Can you drink alcohol in Brunei?

Not publicly, and only for the first four days of this trip. Sale and public consumption of alcohol are banned nationwide in Brunei. Non-Muslim visitors 17 and over may privately import, per Brunei Royal Customs’ own wording, “2 bottles of liqueur (1 litre each)” or “up to 12 cans of beer (330ml),” declared on arrival, for private consumption in your accommodation only, with a 48-hour gap between imports. Royal Brunei Airlines is a dry airline with no alcohol served on board. There’s no bar scene to budget for in Brunei, which keeps the first half of this trip cheap; that changes once you cross into Malaysia.

How do you reach Ulu Temburong?

By road, across the Sultan Haji Omar Ali Saifuddien Bridge, in roughly 30-45 minutes from BSB, with no Malaysian border crossing since the bridge opened in March 2020. A licensed guide handles the transfer and the park permit together as one package; independent entry by any route isn’t possible, and the older speedboat-only or Malaysia-transit descriptions are stale. Booking an overnight rather than a rushed day trip is what makes a week-long Brunei stretch actually worth the extra days, instead of repeating the same BSB sights.

What else should a budget traveller know before crossing the border?

Ramadan (expected roughly mid-February to mid-March 2026, dates shift with the lunar calendar so check current timing) restricts public eating, drinking and smoking during daylight for everyone, including tourists, and changes market and restaurant hours across your Brunei days; plan around it if your dates overlap. Drug trafficking carries a mandatory death penalty on paper, and same-sex acts are illegal under both the civil and Sharia codes; Brunei’s last actual execution was in 1957, and the Sultan extended a moratorium to cover the Sharia Penal Code in 2019, but that stated position isn’t a legal guarantee, so check the current gov.uk FCDO Brunei page or US State Department advisory before you travel. None of this affects an ordinary sightseeing trip; the real cautions in Brunei are legal and cultural, plus wildlife near the water and trails, not crime.

For transport, Brunei International Airport is coded BWN, not to be confused with Kota Kinabalu’s BKI across the border in Malaysia. Grab does not operate in Brunei; the local ride-hailing app is Dart, and a car or day tour is worth arranging for Days 3 and 4 since public buses don’t reach Temburong or the Belait coast easily.

One more honest note before you cross into Malaysia: Brunei holds zero UNESCO World Heritage Sites as of 2026 (Ulu Temburong is a candidate for the country’s first nomination, not an inscribed site yet). Its Kebaya and Pantun traditions sit on a separate UNESCO intangible-heritage list, not the World Heritage list. Gunung Mulu, which you may visit on Day 6, is a UNESCO site, but it’s in Malaysia, not Brunei; don’t credit Brunei with it.

For the official word on Brunei entry, customs and safety, check bruneitourism.com , the gov.uk FCDO Brunei page , customs.gov.bn for the current alcohol allowance, and the US State Department’s advisory before you fly.

Pack modest clothing for the mosques and the rainforest overnight, keep small BND notes for water taxis and the night market, change some cash to ringgit once you’re across the border, and this week will cover both Brunei’s real highlights and enough of Borneo next door to justify the extra days.
