Sugarloaf Ridge
Overview
Sugarloaf Ridge State Park offers a rugged and immersive escape in the heart of Sonoma County. Spanning nearly 4,000 acres, this park provides a dramatic contrast to the manicured vineyards found in the valleys below. It features a diverse landscape ranging from chaparral-covered ridges to lush redwood groves along the headwaters of Sonoma Creek. Visitors come here to disconnect and experience a classic California wilderness that feels remarkably remote despite its proximity to major wine regions.
Location & Surroundings
Tucked into the Mayacamas Mountains between Santa Rosa and Kenwood, the park serves as a natural gateway to both the Sonoma and Napa Valleys. The surroundings are characterized by steep canyons and the towering Bald Mountain, which offers panoramic views of the San Francisco Bay and the Sierra Nevada peaks on clear days. The transition from the valley floor to high ridges creates a unique microclimate that stays comfortably cool under the ancient oak canopy.
Amenities & Park Features
This is a rustic destination, so RVers should prepare for a true dry camping experience. There are no utility hookups available at the sites, making it best suited for self-contained rigs. The campground provides essential comforts including potable water, flush toilets, and token-operated showers. Each individual site features a picnic table and a fire ring. A standout feature of the park is the Robert Ferguson Observatory, which houses several powerful telescopes and hosts regular public star parties.
Nearby Attractions & Things to Do
Outdoor enthusiasts will find over 25 miles of multi-use trails for hiking, mountain biking, and horseback riding. A popular short trek leads to the seasonal 25-foot Sonoma Creek Waterfall, which is particularly impressive after spring rains. Beyond the park boundaries, travelers can explore the world-class tasting rooms of Kenwood and Glen Ellen. For a mix of culture and history, the city of Santa Rosa is a short drive away, offering the Charles M. Schulz Museum and historic rail districts.
Who This Park Is Best For
Sugarloaf Ridge is best suited for travelers seeking a quiet, nature-focused retreat rather than a luxury resort experience. Due to the winding access roads and specific site dimensions, it is most comfortable for small RVs and camper vans under 27 feet. It is a premier choice for astronomy buffs and serious hikers who want direct trail access from their campsite. If your travel style favors dark night skies and morning birdsong over modern digital amenities, this park is an ideal fit.

I am always torn to write a review to a place I want to keep to myself but here we are. A small "private" waterfalls in Sugarloaf Ridge State Park. Note that there is a parking/entry fee of 10 dollars which is totally worth it. Come relax and connect to nature!

Smashin State Park. Really beautiful setting. Lovely wee valley with deer and turkeys wandering around. Great staff and wee shop. Lovely. Only meant to stay a night, stayed 3 nights. Oh, and the observatory up the road a bit is fantastic. Saw Venus.

Absolutely gorgeous State Park with camping areas, great trails, gathering areas, and fabulous nature all around. We did a guided nature tour on one of the easier trails and had a great experience. I highly recommend! A++

Great location! We’ve stayed here about 8 times in the past. Only complaint is that the restrooms and showers don’t seem to be cleaned very often and frequently lack in something like soap or paper towels. Note: Stayed in Site 3. Big and somewhat private site. However, the pad isn’t level with a good amount of decline.

An amazing network of trails of all levels can be found at Sugarloaf Ridge State Park, as well as informational trails that are great for kids. You can pick up a list of trails and rough map at the entrance. We meandered creekside, and looped Hillside Trail to meadow trail, all with amazing scenery. Very clean and well-maintained park, with plenty of rangers. Loads of great picnic areas as well. Can’t wait to return and try more hikes.
