Sarawak opens the door to Borneo's breath-taking spots. From Kuching, the island's most happening city, natural rainforests – where you can witness orang-utans, proboscis monkeys, crocodiles and the world's biggest flower, the Rafflesia – can be visited on day trips, with time at night for a delectable dinner and a beverage by the waterfront. Increasingly gutsy voyagers can take a 'flying box' riverboat up the 'Amazon of Borneo', the Batang Rejang, on their route east to climb from longhouse to longhouse in the cool ambience of the Kelabit Highlands, or to the awesome bat caverns and unprecedented stone formations of Gunung Mulu National Park. For the most obvious opportunity with regards to seeing an orangutan in the wild, go to the Batang Ai district. Wherever you go, you'll experience the radiant, unforced kind disposition and comical inclination that make the individuals of Malaysia's most culturally different state such magnificent host.
