Lake Nunungan

Lake Nunungan is a high-elevation natural freshwater lake in the municipality of Nunungan, Lanao del Norte, Mindanao, Philippines. Located within the Mount Inayawan Range, it is the largest of Nunungan's three lakes along with Lake Gadongan and Lake Daan. Surrounded by forested mountains and rolling highland terrain, the lake is noted for its clear waters, scenic setting, and biodiversity, and serves as a key natural attraction in the interior of Lanao del Norte.

Visitors can expect a remote mountain lake surrounded by forested slopes and grassland within the Mount Inayawan Range. The setting is largely undeveloped with clear freshwater, quiet shoreline areas, and views of surrounding peaks. Access involves mountain roads and trails. Activities are nature-based, including sightseeing, photography, and trekking around the lake area. Facilities are minimal, and the environment is natural and tranquil.

The lake is part of the cultural landscape of Nunungan, known locally as the land of three lakes, and holds importance for the Maranao communities in the area as a source of livelihood and traditional significance.
