Kalimantan, the Indonesian portion of the island of Borneo, is famous for its rich biodiversity and vast, unspoiled rainforests. It is home to a variety of unique wildlife, including orangutans, proboscis monkeys, and sun bears.
Kalimantan is also known for its indigenous Dayak culture, with its distinctive longhouses and traditional rituals. The region's extensive river systems, such as the Mahakam and Barito rivers, serve as important transportation routes, offering unique river cruise experiences.
Furthermore, Kalimantan has several national parks and reserves, like Tanjung Puting National Park, which are popular for ecotourism and wildlife viewing.
