Who We Are

Created in 1972, Midpen is an independent special district that has preserved nearly 65,000 acres of public land and manages 26 open space preserves. Midpen’s boundary extends from San Carlos to Los Gatos and to the Pacific Ocean from south of Pacifica to the Santa Cruz County line.

Midpen’s purpose is to create a regional greenbelt of unspoiled public open space lands in order to permanently protect the area’s natural resources and to provide for public use and enjoyment.

Our Preserves

Preserves include redwood, oak, and fir forests, chaparral-covered hillsides, riparian corridors, grasslands, and wetlands along the San Francisco Bay. Ranging from 55 to over 18,000 acres, 25 preserves are open to the public free of charge, 365 days a year. Visitors will find over 240 miles of trails, ranging from easy to challenging terrain.
