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.

Parking

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.

Events

We have resumed small 12 person social distanced events starting on June 27.   Please see our calendar for details.

CANCELED: RFO Public Star Party @ Robert Ferguson Observatory
Aug 15 @ 8:00 pm – 11:00 pm

The Robert Ferguson Observatory (RFO) is open to the public at least once a month, usually on a Saturday near the time of the New Moon.

Star Parties: Presentations on astronomical topics are given in the classroom throughout the course of the evening. Starting at dusk, the Observatory’s three main telescopes are open for your viewing. Docents set up additional telescopes in front of the building. Friendly and knowledgeable docents are available to answer your questions.

FAQs:

  1. Map and Directions
  2. When to arrive: We keep the observatory open as long as there are visitors, but you must arrive within 3 hours after start time to ensure that we remain open for you. Summer Star Parties begin with tours and presentations until it’s dark enough for observing.
  3. Bring warm clothing, even in summer—observing is done outdoors.
  4. There is a short walk from the parking area to the Observatory and you may wish to bring a small flashlight.
  5. White Light: No white lights should be used after dark; the observatory is a red-light-only area to protect everyone’s night vision. We will supply red cellophane to cover flashlights. Please note:
    ◦ Bring a SMALL flashlight (large camp lanterns, light sticks, etc., cannot be adequately covered by red cellophane).
    ◦ Cell phones or cell-phone flashlights are acceptable but must be covered in red cellophane. (No cell service at the observatory).
    ◦ Some head lamps are difficult to cover with red cellophane. Once covered, head lamps should be worn around the neck or used pointing down as they are usually very bright at eye level.
    ◦ Red flashlights are available for $5 at the observatory.
  6. Alcohol is prohibited on Observatory grounds.
  7. The Observatory is not open to the public except for scheduled events.

Classroom presentations are always offered on Star Party nights even if the weather is poor. For current conditions call the observatory at (707)833-6979.
