Coast Dairies, Nature reserve in Santa Cruz County, US.

Coast Dairies is a state park in Santa Cruz County, California, near Davenport, managed as part of Wilder Ranch State Park to the south. It protects about 7,000 acres (2,800 ha) of coastal land and a seven-mile (11 km) stretch of Pacific shoreline. Its beaches — Sharktooth, Bonny Doon, Yellow Bank, Laguna Creek and Panther — are linked by the California Coastal Trail along the top of the bluff. The ocean-side land was donated to California State Parks in 2006 and remains undeveloped.

This land operated as dairy farms for many decades before The Trust for Public Land purchased it in 1998 to stop development. That purchase transformed the coastline into a protected public space instead of a private commercial area.

The inland tract bought by the Bureau of Land Management in 2014 became the Cotoni-Coast Dairies unit of the California Coastal National Monument, named for the Cotoni people. The name Coast Dairies recalls the dairy farms that worked this land for decades before The Trust for Public Land bought it in 1998.

You can reach several beaches including Sharktooth, Bonny Doon, and Panther by walking the California Coastal Trail along the bluffs. Wear sturdy shoes as the paths change depending on the season and ground conditions vary throughout the area.

The protected area maintains working agricultural zones while also functioning as part of the California Coastal National Monument. This dual role is uncommon and shows how farming and conservation can coexist in the same place.
