What visitors say
Sulawesi’s most famous marsupial, and the one we had hoped to see, is the incredible Bear Cuscus.
Before the five-hour Morning Tour ended, we went to the beach and saw various kingfishers, a woodpecker, a pair of hornbills, and a gecko.
We watched cuscus, black macaques and one night a family of tarsiers.
Just before wrapping up our morning in Tangkoko Forest, we caught a glimpse of the Knobbed Hornbill, also known as the Sulawesi wrinkled hornbill.
