Borneo is a large island divided up by three countries: Indonesia, Malaysia and Brunei. We took a three day boat trip up the narrow rivers in Kalimantan Borneo which is part of Indonesia. The wild life is incredible and nights on the boat were as amazing, with a cacophony of crazy sounds. We were able to see both habituated and wild orangutans which was the main goal. I can't get enough of seeing great apes.
