Tolay Lake Regional Park is located between the Petaluma River and the Sonoma Valley. This unique 1,769-acre property contains pristine farm and grasslands, ridges, a seasonal freshwater lake, ponds, wetlands, and many other natural resources. It provides habitat for several species of special status, including the burrowing owl, California red-legged frog, northwestern pond turtle, golden eagle, white tailed kite, horned lark, northern harrier, and the tricolor blackbird.
Park access is allowed through a day-use permit program, guided hikes, and the annual Tolay Fall Festival, which is held for two weeks each October.
A Tolay Lake Regional Park Master Plan is being prepared to provide a spectrum of outdoor recreation and environmental education opportunities and to protect sensitive habitats and cultural resources. The master planning process will take about two years.

Tolay Lake Regional Park Trails
Length:8.6 miles of trails
Tolay Lake Regional Park offers 8.6 miles of trails that may be accessed with a Day Use permit or on a guided hike. All trails originate from the Park Center complex, which includes picnic areas, a small pond and ranch infrastructure. Hikers may combine several trails to form a loop, or elect to take the popular out and back route to the Three Bridges Vista Point. This popular 5 mile hike follows the Causeway Trail across seasonal Tolay Lake and climbs through oak woodland to join the East Ridge Trail. The trail ends at the vista point, where breathtaking views encompass the 1,769 acre park and much of the San Pablo Bay; including the Richmond-San Rafael Bridge, Bay Bridge, and Highway 37 overpass. Other trail options include shorter trips along Tolay Creek and visits to several ponds. Most of the trails are through open grassland and offer limited shade, so hikers are advised to bring plenty of water and wear sun protection on their adventures.
Leashed dogs and equestrians are welcome on the trails. Please be advised that there is an active livestock operation within the park and park users may encounter cows while on the trail. Information regarding livestock, opening/closing of cattle gates, and much more is provided through the Day Use Permit orientations. Completion of a Day Use permit orientation is required before visiting the park with the following exceptions: attendance of the Tolay Fall Festival, and participation in a guided hike.

Cultural and Natural History
The exceptional cultural and historical value of the Tolay Lake Ranch is well documented. California State Parks Archeologist E. Breck Parkman noted, "Lake Tolay has a unique and perhaps nationally significant prehistoric archaeological history...” The stewardship of the property, ranging from Native Americans to pioneers to enterprising immigrants, is known to span over 8,000 years, and has preserved a unique natural and historical resource. A report prepared for California State Parks notes, "...the Ranch in its entirety possesses a high degree of integrity as a rural historic landscape because of the wide variety of landscape elements that are present." These natural history resources also provide the setting for a site that many consider unparalleled in the state of California for research and public educational activities in relation to Native American archeology, history, and culture.
The Tolay Lake site has been identified as an historic spiritual center for Native Americans from across California. Greg Sarris, Tribal Chairman of the Federated Indians of Graton Rancheria, tells of the rich tradition among his people, "the lake and surrounding area was highly sacred and was considered one of three areas in all of northern California where Indian doctors from different tribes convened for sacred ceremonies and the exchange of ritual objects and songs for the purpose of healing.'' Many of the charmstones found at Tolay Lake were made from rock materials not found in the immediate region, including rocks from Yosemite Valley and northeastern California. Tolay Lake has also been called "Charmstone Lake," because of the abundance of the charmstone artifacts found there. Greg Sarris further notes, "The charmstones collected at Tolay Lake, over 1,000 and still counting, some dating back 4,000 years, mark not only the most significant discovery of cultural material for my people, but no doubt for all native people in California. Nowhere in North America is there such a collection of charmstones."
In addition to an unparalleled glimpse at the pre-European history of California, Tolay Lake Ranch also tells the story of the settling and populating of this region and of California. It provides the opportunity to both study and exhibit the history of immigrant populations that played key roles in local and state history. The artifacts and buildings present on the property document the days of the Spanish settlers and Vaqueros, and the successive waves of Chinese, Irish, Portuguese, Italian, and Mexican immigrants. Over the past forty years, the site had been used for an annual pumpkin festival, drawing crowds of nearly 30,000 each year.
