Tanjung Api Nature Reserve

Tanjung Api Nature Reserve is a protected coastal nature reserve located near Ampana Kota in Tojo Una-Una Regency, Central Sulawesi, Indonesia. It is notable for a natural phenomenon where flammable natural gas escapes from the ground and can be ignited to produce an eternal flame on the beach and shallow sea. The reserve protects coastal forest, beach and lowland ecosystems and is managed as a Cagar Alam for conservation and geological uniqueness.

Visitors can expect a coastal nature reserve landscape with sandy beach, shallow coastal waters, and lowland coastal forest. The main feature is natural gas seepage points on the beach where gas emerges from the sand and can be lit to create small flames. The area is largely natural and undeveloped, with forest vegetation, beach shoreline, and views toward the Gulf of Tomini. Access is typically via a short walk from the nearby village and beach area.
