Travel by private bus to Kampung Batu Puteh, a small village on the Kinabatangan River. Your hosts are from KOPEL, a community-run conservation organization helping villagers build sustainable livelihoods while replanting degraded forest. After learning about their work, board a boat and head upriver to your jungle accommodation. This afternoon, cruise the river at sunset in search of macaques, wild orangutans, proboscis monkeys and other wildlife. After dinner, let the sounds of the jungle take over.
