Upon arrival at Pangkalan Bun Airport, meet and greet by our local guide then transfer to Kumai for boat transfer. The boat is a traditional Klotok wooden river boat about 10m by 2m with a roof which forms the upper deck where you can view the rain forest as it glides by. The guide's team includes the boatman, a cook and expert guide. Lunch is served on the way to Tanjung Harapan, a rehabilitation center for orphaned orangutans, 2 hours away from Kumai. Here the playful and friendly baby orangutans are taught the first stages in fending themselves in the jungle (Subject on availability). In the peaceful afternoon we will slowly explore the quite river by the klotok while observe the monkeys along the riverside.
