Batu Mentas Conservation Center offers a green inland counterpoint to Belitung's beaches and granite boulders. The area protects forest, clear water, and local wildlife, including conservation work connected to the tiny tarsiers that have become a symbol of the island's interior.
It is a better choice for travellers who want a slow nature stop than for anyone expecting polished theme-park infrastructure. Go for the streams, shade, and forest atmosphere, and keep your expectations grounded in conservation rather than spectacle.
