Lake Linow

Lake Linow is a volcanic crater lake located in Lahendong village, Tomohon Selatan, Tomohon City, North Sulawesi, Indonesia. Known for its color-changing water that shifts between green, blue and brownish hues due to high sulfur content and sunlight reflection, the lake lies in a geothermal area surrounded by hills and vegetation. It is notable for its natural sulfur emissions, birdlife, and scenic landscape, making it a popular nature attraction near Manado.

Visitors can expect a small volcanic lake with distinct sulfur-tinged water that changes color with light and chemical composition, surrounded by forested hills and geothermal vents. The site has designated viewing decks and lakeside paths for sightseeing and photography. The sulfur smell is noticeable near the shore. Facilities are basic with food stalls and seating areas. Swimming and boating are not permitted due to high sulfur content.

Lake Linow is a volcanic crater lake formed by volcanic activity associated with Mount Mahawu in the Lahendong geothermal field. The area is part of an active geothermal system that has been used for geothermal energy development in North Sulawesi.

The name Linow comes from the Minahasan language meaning a place where water gathers. The lake is located in the Minahasa region and is regarded locally as a natural landmark within the Lahendong area.
