Nanga Sumpa Lodge

Nanga Sumpa Lodge is located on the banks of the Delok River, approximately 1½ hours longboat ride from the Batang Ai Lake. Borneo Adventure’s tours and activities at Batang Ai are centred on the Lodge.

This award-winning operation was established in 1987 in partnership with the people of Nanga Sumpa longhouse. The lodge includes a dining area, kitchen and guest rooms.

Nanga Sumpa Lodge operates as a type of “village stay”. The accommodation is separate from the longhouse so guests and longhouse residents have their own space and privacy. However, guests are able to visit the longhouse, gain an insight into the Iban way of life and experience a range of activities focused on the clean rivers and pristine rainforest of the local area.


The three Forest Rooms are approximately 35 m2 in size and include ensuite bathrooms. The rooms have mesh on the windows to keep insects out. The rooms share an Iban-style ruai, or covered verandah. Each of the Forest Rooms can comfortably accommodate four people. These spacious rooms are ideal for families or couples seeking a higher level of comfort and privacy than was previously offered at Nanga Sumpa Lodge.

The lodge also has a multi-use annex (The Ruai) suitable for groups, students, film crews or researchers. This building has a multi-use space and its own shower and toilet block. The Ruai is linked to the new Forest Rooms and the main lodge building by a wooden walkway.

A generator supplies electricity from 6.30-10.30 pm to power the main lights and fans. Solar powered nightlights illuminate the public areas, walkways and bathrooms. Meals are prepared in the lodge and feature rice, noodles, chicken, fish, fresh jungle vegetables and other local delicacies.

Nanga Sumpa is a small jungle lodge located in a relatively remote area of Borneo. The facilities reflect the remote location and are somewhat basic. Many of our guests don’t mind this as the beauty of the area and the Iban people are the real attractions. However, we appreciate that the accommodation may not be as luxurious as some travellers require.

The Location – Ulu Ai

The lodge is located in a pristine and isolated area of Batang Ai know as Ulu Ai, the upper reaches of the Ai river catchment. A visit to a longhouse is often the highlight of a trip to Sarawak, offering a glimpse into the lifestyle of the various tribes who have for generations lived in the remote interior of Borneo.

While there are many areas in Sarawak where longhouses can be visited, Ulu Ai is one of the best. What makes Ulu Ai so special is the natural environment and stunning scenery. Clean rivers and jungle streams, refreshing waterfalls and undisturbed tracts of rainforest allow you to combine a range of outdoor activities with a longhouse visit.

Tours & Activities

Nanga Sumpa Lodge serves as a base for a range of nature-based activities and excursions and offers visitors the chance of learning about the culture and lifestyle of the Iban community who live in the nearby longhouse.

Activities at Nanga Sumpa 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 that take you along streams and through farmlands to primary rainforest. Orangutan live in the area and sometimes it is possible to see the “man of the forest” in its natural environment.
