Lake Lanao is the largest lake in Mindanao and the second largest lake in the Philippines, located in Lanao del Sur with Marawi City on its northern shore. Formed by volcanic damming, it is recognized as one of the world's ancient lakes. The lake feeds the Agus River and supports hydroelectric power generation. Surrounded by rolling hills and Maranao communities, it is culturally central to the Maranao people and offers scenic views and tranquil waters.

Visitors can expect a large freshwater lake surrounded by gentle hills and lakeside communities, with Marawi City along the northern shore. The shoreline offers open views of calm waters, distant mountains, and small fishing boats. Areas around the lake provide viewpoints for sightseeing and photography. Visitors can observe daily lakeside life, take short boat rides where available, and view the outlet toward the Agus River. The environment is generally tranquil and rural.

Lake Lanao is an ancient lake estimated to be millions of years old, formed by the damming of a river by volcanic activity and lava flows. It has long supported settlements around its shores and later became important for hydroelectric power generation through the Agus River system, which drains the lake toward Iligan Bay.

The lake is central to Maranao culture and identity. The name Maranao translates to People of the Lake, and Ranao means lake in the local language. The lake and its surroundings are integral to traditional livelihoods, folklore, and community life of the Maranao people in Lanao del Sur.
