About Sugarloaf Ridge State Park

Sugarloaf Ridge State Park offers stunning vistas, diverse wildlife, and excellent hiking trails in the heart of California's wine country.

Wilderness Landscape & Natural Heritage

Sugarloaf Ridge State Park is located in Sonoma County, California, and is renowned for its stunning views, particularly from Bald Mountain, which provides a panoramic outlook of the Napa Valley and on clear days, even the Sierra Nevada. Established to protect the area's rich ecology, the park features numerous trails that wind through oak woodlands, chaparral, and riparian habitats. The park is home to a variety of wildlife, including deer, foxes, and over 100 species of birds, making it a paradise for birdwatchers. The area was historically inhabited by the Wappo people, and remnants of their presence can still be observed in the park. Visitors can enjoy a range of recreational activities, including camping, hiking, and stargazing, taking advantage of the park's location away from major city lights, making it one of the best stargazing spots in the area.
