Visiting Sumatra can means neverending actions. Starting from orangutan sanctuary in Bukit Lawang, worldclass diving in Pulau Weh, enjoying spicy Padang cuisines, surfing on wild Mentawai islands, relaxing on the shore of Lake Toba, bagging the top of Mount Kerinci of Jambi, amazed by granite beaches of Belitung, to dolphin sightseeing at Kiluan, Lampung. The land is also filled with every unique and imaginable rainforest fauna. Not only red-haired orangutan, but also all sorts of monkeys that swing on treetops, in addition to Sumatran special tigers, rhinoceroses, and elephants. With almost 40 million inhabitants on this island alone, the varieties of cultures in Sumatra will also gives you non-stop thrill. From the devout Muslim of Aceh, outspoken and friendly Batak people, matrilineal Minangkabau of Padang, sizeable Chinese communities of Bangka-Belitung, to semi-primitive tribesmen of Nias. All of them, with their own distinct cultures and languages, living in one island, united by mutual respect for centuries.
