The Philippine Tarsier and Wildlife Sanctuary near Corella is one of the better places in Southeast Asia to see the extraordinary Philippine tarsier in semi-wild conditions. The sanctuary protects a patch of secondary forest where tarsiers live free-ranging, with guides who know where individual animals are resting during the day.
Tarsiers are nocturnal and spend the day sleeping in low branches, which makes them easy to observe without disturbing them — you stand quietly and look at an animal the size of your fist clinging to a branch a metre away, its enormous saucer eyes closed. The sanctuary is strict about flash photography and noise, which is the right approach; tarsiers under stress die easily. A short but worthwhile stop on the Chocolate Hills circuit, about 45 minutes from Tagbilaran.
