Welcome to Sugarloaf Ridge State Park
Sugarloaf Ridge State Park contains the headwaters of Sonoma Creek. It runs through gorge and canyon, across the meadow floor, beneath scenic rock outcroppings, and is surrounded by redwoods and ferns. With 47 family-sized campsites and 25 miles of hiking trails, it is the perfect place to spend time outdoors!
