A longboat trip takes you down the Sungai Melinau and up the Sungai Tutoh to the small Long Lansat stream.

Crystal clear waters cascade down a narrow valley between steep slopes. Lush rainforest plants crowd in over the water; the soft sounds of birds, insects and the stream relax you. Take your time enjoy a river walk and a swim in this secret and precious part of Mulu. Why not visit the Penan community at Long Iman on the way and learn a little about their customs?
