Campsites at Sugarloaf Ridge State Park are open.  

Due to COVID-19, campsites rules and procedures in place designed to keep visitors and staff safe, and social distancing protocols are still enforced throughout the park. Here’s how camping will be different at Sugarloaf Campground:

  1. The following sites remain closed: 8, 13, 17, 35, 38.
  2. Only two cars per site, with one family group and no outside visitors, are allowed.
  3. Each site will have its own portable toilet (porta potty) for the exclusive use of that site. The toilets will be cleaned upon campsite turnover.
  4. We encourage visitors in self-contained RVs to make use of their own facilities rather than the park facilities.
  5. Some flush toilet facilities and showers remain open and our staff cleans them 3-4 times per day.
  6. We recommend bringing your own soap along with cleaning supplies such as wipes.
  7. The tent rental program is open our staff will disinfect tents between each use.

Reservations for Sugarloaf campsites may be made 48 hours in advance here.

Reserve a tent here

For same-day first-come-first-served reservations, please call the park at 10am on the day you want to arrive at 707-833-6084 or 5712.

We are providing additional cleaning services free of charge. However, we are asking for a $10 donation per day—only from those that are able—to cover our additional cleaning and porta potty costs.

We ask all park visitors to adhere to the Sonoma County health ordinance guidelines, which require the use of masks or face coverings when unable to keep a minimum distance of six feet from others not in your immediate household.

Anyone with coronavirus symptoms (commonly a fever, dry cough, or shortness of breath) should not come. Those with reservations may cancel with no penalty. Read more about coronavirus symptoms.

Sugarloaf is open for day use.

Sugarloaf Ridge State Park is now open for day-use parking and camping. The restrooms are open and are being disinfected 3-4 times per day.

The visitors center,  picnic area, and the campground remain closed.

To reduce interactions at our park, please purchase your day pass or annual pass online before you arrive.

Social Distancing and Face Covering Information

Park visitors must comply with social distancing, hygiene, and face-covering requirements:

  • Stay at least 6 feet from others who are not part of your household.
  • Carry a face covering at all times. Coverings must be worn outdoors when you cannot stay 6 feet from others, such as when passing others on a trail.
  • Do not visit a park if you have any symptoms of Covid-19: fever, cough, sore throat, shortness of breath, unusual headaches, severe fatigue, chills, gastrointestinal symptoms, and lost sense of smell or taste.
  • Do not use group facilities.
  • Do not use drinking fountains. Bring your own water.
  • Pack out your litter to reduce the amount of trash parks staff and visitors may come into contact with. 
  • Cover coughs or sneezes with a tissue and pack out your tissue for disposal at home.


When parking, please observe social distancing protocols. If the park becomes too crowded, we may temporarily close access. Please come early or later in the day if you want to be sure of entry.

The practice of Forest Therapy has been shown to improve health and well-being.

Have you heard about Shinrin-yoku or Forest bathing? Here is an opportunity to take a walk and experience the practice for yourself. Learn techniques to maximize the health benefits and stress reducing qualities of this walking practice. Shinrin-yoku originated in Japan and is gaining popularity in the United States for its documented Health benefits.

Sugarloaf Ridge State Park hosts a Forest Therapy Series as part of its ParksRx Program the 4th Saturday of each month. These walks are led by certified ANFT (Association of Nature and Forest Therapy) practitioners. See http://www.natureandforesttherapy.org/ for more info about this practice.

Here at Sugarloaf Ridge State Park, we see many families throughout the year and many wish they had planned to stay longer than a weekend.
