At 3,400 acres, Tolay Lake is the largest of Sonoma County’s regional parks. It’s named for the seasonal lake that forms in the valley between its hillsides.

The park includes Tolay Creek, extensive grasslands, and open ridges with views of San Pablo Bay, the San Francisco skyline, and Bay Area peaks

The park offers 11 miles of trails for hiking, mountain biking and horseback riding. It also provides habitat for a variety of wildlife, especially golden eagles, burrowing owls, and other birds of prey. Visitors may combine several trails to form looped routes or longer out-and-back excursions.

Grazing is an important conservation tool for land managers and visitors may encounter cattle grazing along trails. Cattle are not aggressive by nature. In many cases, cattle will keep to themselves and move out of your way when you approach. Livestock, like wild animals, should be treated with respect.
