Tolay Lake Regional Park is located about 8 miles southeast of downtown Petaluma, bordered by hills between the Petaluma River and Sonoma. The park will open daily beginning Oct. 27, 2018, after having been open weekends only while its master plan was developed. 

At 3,400 acres, Tolay Lake is the largest of Sonoma County's regional parks. It is named for the seasonal lake that forms in the valley between its hillsides. The park also 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 trails for hiking, mountain biking and horseback riding and is the site of the annual Tolay Fall Festival each October. 


Tolay Lake Regional Park offers more than 11 miles of trails across mostly open grasslands. When the park opens permanently, visitors will have new access to its southern acreage via an extension of the West Ridge Trail. 

Cultural and Natural History

The park is known for its significant Native American and ranching histories. It also provides habitat for a variety of wildlife, especially golden eagles, burrowing owls and other birds of prey.  

Permit Program

A day-use permit program has allowed the public to visit the park on weekends for the past decade. Beginning Oct. 27, 2018, the park will open daily and permits are no longer required.
