Located on the banks of the Delok River, the Nanga Sumpa Lodge is around four and a half hours by car from Kuching, plus another hour and a half on a longboat from the Batang Ai Lake jetty. It’s a relatively remote area of Borneo, and its basic yet comfortable facilities reflect its location. This award-winning operation was established in 1987 in a partnership between the people of Nanga Sumpa and a local tour operator.

Nanga Sumpa Lodge serves as the base for a range of nature-based activities and excursions, and offers visitors the chance to learn about the culture and lifestyle of the local Iban community. Activities include travelling further upriver by longboat to have a swim at a waterfall, visiting the longhouse and surrounding farms, participating in the daily activities of the Iban people, and jungle trekking on trails along streams and through farmlands to primary rainforest.


Forest Wing – 3 new rooms built in 2014. Rooms are basic with ensuite bathroom and communal verandah. Each room can accommodate up to 4pax and great for families or group of friends wanting more privacy than previously offered. 

Ruai Wing – 5 rooms with communal shower and toilet block, and a shared multi-use space. 

* Nanga Sumpa Lodge is a jungle lodge located in a relatively remote area of Borneo. The facilities reflect the remote location and are somewhat basic, and accommodation may not be as luxurious as some travellers require. If you are looking for a bit more luxury, the Batang Ai Longhouse Resort by Hilton offers hotel standard facilities and air-conditioned rooms.


Local foods prepared at the lodge in communal setting. Vegetarians and special diets catered for.
