Several North Bay California State Parks continue to be closed due to impacts associated with the LNU Fire Complex. The parks are Trione-Annadel, Sugarloaf Ridge, Robert Louis Stevenson State Parks and the Bale Grist Mill, Sonoma, Jack London and Petaluma Adobe State Historic Parks. It is imperative that the public stay out of closed areas as safety hazards exist such as burned trees and damaged facilities. Park staff are actively assessing field conditions, and park rangers are patrolling closed parks. The park will open as soon as it is safe and normal park operations are in place. Unauthorized access is strictly prohibited in closed areas, it is unlawful to enter areas that have a District Superintendent's closure order (see below).

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 at times by redwoods and ferns. 

A 25-foot waterfall flows after the winter rains. There is a self-guided nature trail along Sonoma Creek that starts near the picnic area.  Dogs must be on a leash under your control at all times. Dogs are not allowed on trails. Dogs must be in a tent, camper or enclosed vehicle during the night.

Within the oak woodland and chaparral, the park has 25 miles of trails for hiking and horseback riding. 

Deer, gray foxes, the occasional bobcat and coyote can be seen in the park. In spring, wildflowers provide a colorful palette across the green hills. 

On a clear day, visitors can see views of the Sierra Nevada and the Golden Gate bridge from the 2729-foot summit of Bald Mountain. 

The non-profit Valley of the Moon Observatory Association provides year-round astronomy education and interpretation programs at the Robert Ferguson Observatory within Sugarloaf Ridge State Park.  Program fees vary, some are free with the payment of the park's Day Use Fee. There are three telescopes and the New Generation 40-inch Telescope Project at the Ferguson Observatory which will be one of the largest telescopes dedicated for public viewing. 

The park is about one hour away from San Francisco and seven miles east of Santa Rosa.
