Buena Vista Park, Public park with oak groves in Haight district, San Francisco, United States

Buena Vista Park is a public park on a steep hill rising to 575 feet (175 m) in the Haight-Ashbury and Buena Vista Heights neighborhoods, covering 38.3 acres (15.5 ha). It is bounded by Haight Street to the north and by Buena Vista Avenue West and East. The hill is made of sand and San Francisco chert from the Mesozoic era, and the paths use the slope to reach lookouts over the city, with a small lawn at the peak.

The park was established in 1867 as San Francisco's first public park on natural hilltop terrain. Over the decades, the land was developed with tennis courts, walking paths, and landscaping to create a recreational space for the growing city.

The park's name, Spanish for "good view," was adopted in 1894, replacing the original Hill Park. Along the west-side paths, gutters built by WPA workers use broken headstones from the city's Victorian cemeteries at Lone Mountain, moved to Colma in the the 1930s; a few inscriptions still face up and can be read.

The park is accessible from multiple entry points, with the main stairs beginning at Haight Street where most visitors enter. The trails are well-maintained throughout, but climbing to the summit requires effort due to the hilly terrain.

The northeast corner staircase has a large peace symbol of the Campaign for Nuclear Disarmament type planted in flowers. Farther south, a tennis court sits just inside the park at Duboce and Buena Vista East streets. The N Judah streetcar runs beneath the hill through the Sunset Tunnel.
