Brunei has no public bus network and no ride-hailing services operate in the country. The primary transportation option for visitors is taxi, which must be arranged by phone or through hotels because taxis do not cruise for street hails. Most visitors rent cars at Brunei International Airport where international agencies operate. Driving is on the left side of the road, inherited from British Residency governance that lasted from 1906 to independence in 1984. Road signage appears in Malay and English. The highway system connects all four districts and road quality is high because oil and gas revenue funds infrastructure maintenance. Petrol costs approximately 0.53 Brunei dollars per liter, among the lowest prices globally due to domestic production.
Reaching Temburong District from the capital requires crossing Brunei Bay. The Sultanah Saleha Bridge opened in 2020, spanning 30 kilometers and eliminating the previous requirement to transit through Sarawak, Malaysia or take a boat. Before this bridge existed, visitors needed exit and entry stamps to pass through Malaysian territory for the 15-minute drive between Brunei-Muara District and the Temburong exclave. Water taxis still operate from Bandar Seri Begawan to Bangar in Temburong, departing when full rather than on fixed schedules. The boat journey takes 45 minutes.
Kampong Ayer, the water village in the capital, operates its own water taxi system with fixed per-person fares of one Brunei dollar for short crossings. These narrow wooden boats connect the stilted settlements that house approximately 30,000 residents. Charter boats for longer journeys or tours cost 20-30 Brunei dollars per hour. No bridges connect most Kampong Ayer structures, making boat transport necessary rather than optional. Walking between buildings requires using elevated wooden walkways where they exist.
Domestic flights do not exist because distances are short. Bandar Seri Begawan to Kuala Belait, the farthest major town, measures 85 kilometers by road and takes approximately 90 minutes by car. All locations a visitor might reasonably want to reach are accessible by vehicle within two hours from the capital. Rental cars cost 60-100 Brunei dollars per day depending on vehicle size. International driving permits are accepted for stays under three months.
Brunei sits 40 kilometers north of the equator and experiences a tropical equatorial climate with no distinct dry season. The term "monsoon" appears in some travel literature but daily weather patterns show minimal seasonal variation. Rain falls throughout the year. Monthly rainfall averages range from 250 millimeters in March to 400 millimeters in January. Temperature variance across the calendar measures approximately three degrees Celsius. Daily highs consistently reach 30-32 degrees Celsius while overnight temperatures drop to 23-24 degrees. Humidity remains above 80 percent year-round.
The months with relatively less rainfall are February through April, but this designation means 250-300 millimeters of monthly precipitation rather than genuinely dry conditions. Rain typically arrives as afternoon thunderstorms lasting one to three hours rather than all-day events. November through January receive the highest rainfall totals and the South China Sea produces rougher conditions that occasionally prevent boat travel to offshore areas. Travel to Ulu Temburong National Park remains possible year-round because access roads and the Temburong River boat transfers operate unless active flooding occurs, which happens rarely.
Timing a visit around Sultan's Birthday on July 15 provides access to national celebrations, military displays, and the opening of Istana Nurul Iman palace to the public. This is the only date when visitors can enter the palace, which holds the Guinness World Record as the world's largest residential palace with 1,788 rooms. National Day on February 23 features similar public events but without palace access. The dates of Hari Raya Aidilfitri and Hari Raya Aidiladha shift annually based on the Islamic lunar calendar. During Ramadan, most restaurants close during daylight hours and only hotel restaurants serve food to non-Muslims before sunset.
The tourism industry in Brunei operates continuously without peak or low seasons in the traditional sense. Hotel prices remain stable across months. Flight prices to Brunei International Airport fluctuate based on regional demand patterns in Southeast Asia rather than Brunei-specific seasonality. The country receives fewer than 300,000 international visitors annually according to government statistics, meaning crowding is not a consideration at any time of year.
Brunei operates as a high-income economy where government subsidies for citizens do not extend to visitor services. Accommodation costs begin at 50-70 Brunei dollars per night for basic hotels in Bandar Seri Begawan. Mid-range hotels cost 100-150 Brunei dollars. The Empire Hotel and Country Club, the largest resort property, charges 300-600 Brunei dollars depending on room category and dates. Kampong Ayer has one homestay program coordinated through the tourism department where overnight stays with local families cost approximately 80-100 Brunei dollars including meals and boat transfers.
