Los Trancos Open Space Preserve

Los Trancos Open Space Preserve is a 274-acre (1.11 km2) open space preserve, located in San Mateo and Santa Clara Counties, California, near Los Altos Hills, California.

The preserve's acreage was purchased by state senator Louis Oneal in the early 1900s, who raised horses there.

The preserve was acquired by the Midpeninsula Regional Open Space District in 1976.

Additionally, a 1.5-mile (2.4 km) trail follows the main break caused by the 1906 San Francisco earthquake.

This trail includes several interpretive stations that point out various quake-caused features and phenomenon.
