Two or three days can cover the main stops: one for Bandar Seri Begawan’s mosques, the Royal Regalia Museum and Kampong Ayer, another for Ulu Temburong, and a third for Muara or Jerudong. Ask the park operator for the actual bridge-road and river transfers, departure time and return, rather than budgeting around a fixed speedboat journey. Choose validity for the visit you have booked.

Brunei fits naturally into a Borneo itinerary with Sarawak or Sabah. An onward journey into those Malaysian states is a separate border and coverage question. Travelling to Brunei's Temburong district, however, can use the Sultan Haji Omar 'Ali Saifuddien Bridge without passing through Malaysia. Confirm your actual route and any border requirements, and check whether the selected plan explicitly includes Malaysia when your trip enters it.

Confirm the route with your park operator. Temburong can be reached by road over the Sultan Haji Omar 'Ali Saifuddien Bridge within Brunei; the park visit may then include a longboat journey upriver. River-based itineraries may also be offered, so check the actual departure point, transfers and current access arrangements. Download your booking and route before entering the rainforest, where dense canopy can reduce reception.

Both are worth doing, and they show different things. By day you can land in Kampong Ayer and walk the boardwalks of one of the world's largest stilt settlements, seeing it as somewhere people live rather than as a view. A run along the river at dusk gives you the silhouette of the settlement and the mosques instead. Water taxis leave from the Bandar Seri Begawan riverfront; agree the fare and the pickup before boarding, because arranging a return mid-river is the harder version.

For most travellers it works better as a stopover than as a stand-alone destination, and that is not a criticism. It is a small sultanate with one urban hub and a handful of short excursions, so it pairs naturally with Sabah or Sarawak on either side. If Kampong Ayer, the mosques and Ulu Temburong are what you came for, two or three days is a complete visit. Plan the data around a short stay rather than a long one.

Brunei is a dry country and its rules on alcohol are shaped by Sharia, so do not build an evening around buying a drink locally. It is among the most common practical questions asked before a first visit, and the honest answer is to plan evenings around food, the riverfront and the lit mosques instead. Rules of this kind are national and can be revised, so confirm the current position from an official source before you travel.

The Sultan Omar Ali Saifuddien Mosque and the Jame'Asr Hassanil Bolkiah Mosque are working places of worship as well as the capital's two landmark buildings, so dress conservatively and cover up. Arrangements for visitors who are not there to pray vary and can shift around prayer times, so check them on the day rather than relying on an itinerary written weeks earlier — one more reason to have your data working before you reach the gate.
