The famous Bill and Dave Hikes are back! Bill & Dave have retired, but we’re excited to continue in their footsteps by leading these wonderful hikes with the support of our volunteers and parks staff. Join us to check out favorite trails and parks, preview new parklands, learn about the local ecosystem and enjoy a day out in nature. These are moderate to strenuous hikes with longer mileage, so be sure to bring water, snacks or lunch and wear sturdy hiking shoes. Parking is $7 or free for Regional Parks members. For more information, contact hike leader Alexis Puerto-Holmes at

Join us for the series:

  • Saturday, Sept. 4 - North Sonoma Mountain Regional Park & Open Space Preserve - We'll hike about 10 miles roundtrip on the North Sonoma Mountain Ridge Trail to Deer Camp in adjacent Jack London State Historic Park, experiencing about a 1,700-foot elevation gain. We'll spend some time taking in the views of Bennett and Sonoma Valleys and surrounding peaks, discussing the natural features of the landscapes and appreciating the connectivity of the regional-state parks. 

  • Sunday, Nov. 28 - Tolay Lake Regional Park - We'll hike to the Three Bridges Vista Point via the Causeway and East Ridge Trails, returning on the Causeway, Pond and Historic Lakeville Road Trails. We'll cover about 8 miles total with minimal elevation gain (about 540 feet). We'll enjoy views of San Pablo Bay, the bay bridges, and the San Francisco skyline (if it's a clear day) and soak up the big-sky feeling of this special park. We'll discuss the park's natural features and cultural history and touch on future plans for Tolay Lake Regional Park, the largest of the regional parks. In keeping with the tradition of Bill and Dave's Hikes, this hike will happen rain or shine.
