New Entry Access Completed at Olompali State Historic Park
The new entry access to Olompali State Historic Park (SHP) has been completed by the California Department of Transportation (CalTrans). As of July 21, 2014 all traffic to Olompali will need to enter from Atherton/Redwood Blvd. Directional signage from both northbound lanes and southbound lanes off Highway 101 are in place. Access to Olompali SHP is no longer available by exiting directly off Highway 101.
This project is part of the overall CalTrans highway construction improvements and the permanent new realignment to the entrance of Olompali SHP. At this time, we do not anticipate any traffic issues for visitors, and permanent directional signage to the park has been completed and is in place.
The park overlooks the Petaluma River and San Pablo Bay from the east-facing slopes of 1,558 foot Mount Burdell.
The name "olompali" comes from the Miwok language and may be translated as "southern village" or "southern people." The Coast Miwok inhabited at least one site within the area of the present-day park continuously from as early as 6,000 BC, until the early 1850s.
Olompali contains "kitchen rock," a large boulder used as a mortar in which early people ground acorns and seeds into a fine flour for food preparation. Many women would gather near such grinding rocks to prepare food and socialize.
The park is accessible from both the Northbound and Southbound lanes of Highway 101. Exit at Atherton Blvd. and follow posted directional signs to the park.
The park has hiking and horseback riding trails and a shaded picnic area. Please be aware that no dogs or bikes are allowed on the park trails. The park day use fee is currently $8.00 per vehicle. Credit card only.
The visitor center is usually staffed by a volunteer on Saturday afternoons, Noon-3pm.
A project is underway to build several structures representative of a Coast Miwok village. The village will be used as an interpretive and educational site. Visitors to the park can see two kotchas (houses), one made from redwood bark and another made with bundles of native tule reeds. There is also a nicely labeled native plant garden.
