Plan Your Visit

The most popular things to do at Sugarloaf Ridge State Park are hiking to the top of Bald Mountain, walking to the 25-foot seasonal waterfall on Sonoma Creek, camping in the creekside meadow and stargazing at the Robert Ferguson Observatory. The park also has picnic areas, a Visitor Center with a gift shop, horseback and bike routes, and a calendar of guided events. It is open 6 a.m. to 10 p.m. daily, and day use is $10 per vehicle.

Top Things to Do

• Climb Bald Mountain. 5.6 miles round trip to the 2,729-foot summit, with views reaching the Golden Gate Bridge on clear days (Bald Mountain).
• See the waterfall. A 2-mile loop through redwoods to a 25-foot fall that runs after winter rain (waterfall).
• Camp by Sonoma Creek. 47 family sites, a group camp and glamping tents, open year-round (camping).
• Look through a big telescope. Night and solar viewing at the Robert Ferguson Observatory on select weekends (observatory).
• Walk the solar system. The Planet Walk lays the planets out to scale along the Meadow Trail (hiking).
• Spring wildflowers. The operator says the displays run from early to late spring and into early summer (weather and seasons).

A One-Day Plan

1. Morning: arrive early, pay at the kiosk or pay station, and hike Bald Mountain before the heat, or the shorter Vista Trail Loop.
2. Midday: picnic in the main day-use area across the creek from the campground. It has tables and barbecues.
3. Afternoon: stop at the Visitor Center for maps and park history, then walk the Pony Gate-Canyon Loop to the waterfall in the shade of the canyon.
4. Evening: on an observatory viewing night, stay for the stars; check rfo.org for the schedule first.

Facilities

• Visitor Center by the creek near the campground entrance, with park history, information and a gift shop, open 9 a.m. to 5 p.m. Limited Wi-Fi works around the building.
• Picnic areas with tables and barbecues, plus an accessible vault restroom at the main day-use area.
• Restrooms and drinking water in the developed areas; showers in the campground bath house.
• Firewood for sale at the Visitor Center or from the camp host.

Pack the food and water you'll need; State Parks' brochure reminds hikers to carry drinking water.

Events and Programs

The park lists a regular calendar of guided programs: forest-bathing and yoga hikes, backpacking courses, workshops and solar observing. Upcoming events in fall 2026 included a Park RX forest-bathing walk on October 25, solar observing on November 7 and a yoga hike on November 21. School groups can arrange free day-use visits through the park office, with volunteer docents sometimes available.

Fishing

Trout fishing in Sonoma Creek is best in late spring and early summer, State Parks' brochure says, and the creek is not stocked. Seasons vary, so check current California fishing regulations; anglers 16 and older need a California fishing license.

Horseback Riding and Mountain Biking

Horses and bikes may use only designated, named trails, and some are posted closed to one or both. Bikes are limited to fire roads and service roads, with a 15 mph limit, and must yield to horses (trail rules).

Wildlife Watching

Look for deer, gray foxes and, now and then, a bobcat or coyote. Keep your distance, never feed wildlife, and store food at night to keep raccoons out of it.

Bringing a Dog

The campground welcomes dogs, the picnic area and on paved roads in the main park area, on a leash of six feet or shorter. They are not allowed on any trail, dirt road or backcountry area, which rules out every hike above (dog rules).
