Orangutans
Borneo is the third largest island in the world (287,000 sq. mi) and is home to the largest mountain in South East Asia, Mount Kinabalu at 13,455 ft high; and, has one of the largest, most intricate cave systems on earth containing huge underground rivers and bats by the millions. Eco-travelers will marvel at the stunning variety of flora and fauna that inhabit the vast rainforest. As a honeymoon location, Borneo offers a plethora of activities, from scuba diving and snorkeling to mountain climbing, cave exploration and, if one is lucky enough, seeing orangutans in their natural habitat.
