Mountain Lake


Mountain Lake is a natural lake on the southern border of the Presidio. It is an important place for both nature and history.

In 1776, Captain Juan Bautista de Anza's scouting party camped here before establishing the military outpost that would become the Presidio. Later the lake was a water source for the growing city of San Francisco. Mountain Lake's fresh waters have also long made life possible for plants, birds, and other wildlife.
Today, Mountain Lake is a peaceful oasis and popular visitor destination. It is also a living laboratory for restoration and is being brought back to health with the participation of the community.
