Situated next to Mountain Lake where the southern edge of the Presidio meets the Richmond District, this park offers many different amenities. Dog lovers flock here for the dog run at the eastern end of the park. In the middle of the park are four full tennis courts, and nestled closer to the lakeshore is a half basketball court. Children enjoy the sand-floor playground at the 12th Avenue entrance that features slides, swings, and a multi-level play structure, while runners can make use of the built-in fitness circuit. New restrooms are available on-site. There is a covered picnic/card playing pavilion opposite the 9th Avenue entrance. A great meadow is a favorite place to spend the afternoon for a picnic or to rent for children’s birthday parties. Mountain Lake Park is owned by the San Francisco Recreation and Parks Department.
