Lake Linow

Lake Linow is a striking volcanic lake located in Lahendong Village, South Tomohon Sub-District, near the city of Manado in North Sulawesi, Indonesia. The lake is renowned for its dramatic color changes—shifting from blue to green to brownish-yellow—due to the unique chemical composition and high sulfur content resulting from hydrothermal activity and past volcanic eruptions. The area is bordered by Mount Lokon and Mount Mahawu, providing a stunning natural backdrop and panoramic views for visitors.

The lake’s surface area is about 34 hectares, and its shores are dotted with hydrothermal vents that emit hot gases, contributing to the strong sulfuric odor often described as smelling like rotten eggs. While this scent can be intense, it is a natural byproduct of the lake’s volcanic origins. The name "Linow" comes from the Minahasa language, meaning "water gathering place". Despite its beauty, swimming or entering the water is strictly prohibited because of the high and dangerous sulfur levels.

Lake Linow in Minahasa, North Sulawesi, is a favored destination for birdwatchers due to its rich and diverse birdlife set against a dramatic volcanic landscape. The lake and its surrounding areas serve as habitat for a variety of both resident and migratory bird species, making it a vibrant spot for avian observation.

Some notable bird species commonly observed at Lake Linow and its vicinity include:

• Oriental Darter
