Guide to Hiking in Sonoma County

Armstrong State Natural Reserve

Comprising 1,768 square miles and stretching for 55 miles along the Pacific Ocean, Sonoma County is big. This gorgeous region is also an ecological paradise containing countless microclimates and an immense diversity of species.

So, in a county this huge, stunning, and varied … how do you even begin to figure out where to go for a hike? It’s easy with this guide. 

Sonoma County State Parks

The 11 California State Parks located in Sonoma County cover an extraordinary diversity of geographical terrain that reflects the county’s beauty. Our state parks overlook the Pacific Ocean and include many beaches, and they are home to rivers and lakes, mountains and valleys, redwood forests and pygmy forests—and even vineyards.

Some state parks not only offer opportunities to explore the beauties of nature, they also tackle history. If you want to learn more about California’s exciting and colorful past in a fun way, just visit Petaluma Adobe, Sonoma, Fort Ross, or Jack London state historic parks—and prepare to be amazed.

These parks also offer a wide range of activities, including hiking, biking, and horseback riding. Whether you’re looking for flat, short ‘n easy trails or extreme, let’s-tough-it-to-the-top punishment, you’ll find it in one of Sonoma County’s state parks. Want to hike in and spend the night, enjoy a lakeside picnic, and wander through a redwood grove? Yep. All that and so much more.

Sonoma County Regional Parks

Sonoma County’s thriving regional park system consists of more than 50 parks—including trails and open spaces—and encompasses nearly 60,000 acres. Parks run the length and breadth of the county, stretching from Bodega Bay in the south to The Sea Ranch and Gualala in the far north, and from the Pacific Ocean in the west to Sonoma Valley on the county’s eastern edge. The newest regional parks are Taylor Mountain (2013) and North Sonoma Mountain (2015).

Regional Park trails cover a vast terrain, and not just in miles. No matter your experience and hiking level, you’ll find a hike that’s perfect for you!

There are Regional Park trails for history-lovers, geology mavens, birdwatchers, autumn leaf-peepers, spring wildflower fans, and wildlife lovers. Some trails lead to lakes where you can fish, swim, or rent a kayak, while other trails lead to softball fields, ocean beaches, and dog parks. There are also trails geared to families with young children, and to people with accessibility needs.

Tip: If you want to just hike one way on the rugged trails in the state and regional parks in the Sonoma Valley, hop on the Sugar Shuttle, a six-passenger van with routes between North Sonoma Mountain Regional Park, Jack London State Historic Park, Sugarloaf Ridge State Park, and Hood Mountain Regional Park. The shuttle makes hourly loops the second weekend of each month, and every weekend in May and September, with service on one of the routes each weekend. Experienced hikers can park their vehicle at the trail’s end and take the shuttle to the starting trailhead. The suggested donation is $10 per person; reservations recommended. Learn more about the Sugar Shuttle

Guided Hiking Tour Companies

If you’re new to the county or just want to explore different terrain with a knowledgeable guide, consider a guided hiking tour with a company that specializes in hiking and walking tours. These companies offer standard tours, but will usually be happy to create a tour to match your interests.
