Sungai Wain Protection Forest

Sungai Wain Protection Forest is a large lowland rainforest reserve on the outskirts of Balikpapan, valued for its role in protecting water sources and preserving East Kalimantan’s biodiversity. Visitors come for guided walks through primary and secondary forest, chances to spot birds, macaques, and, occasionally, orangutans, and a quieter alternative to the city. It suits travelers interested in nature, conservation, and tropical forest ecosystems rather than conventional sightseeing.
