Welcome to Sugarloaf Ridge State Park

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. With 47 family sized campsites and 25 miles of hiking trails, it is the perfect place to spend time outdoors with your family!

Camping:  We have 44 campsites open, both reservable and first-come, first-serve in our lovely creekside campground.  And our Glamping sites opened April 1st – reservations available and booking fast!  For first-come-first-served sites call at 10 am.  Call ahead, these sites fill fast.

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.

Mushroom Hike @ Sugarloaf Ridge State Park
Jan 23 @ 10:00 am – 12:00 pm

Enjoy some fungi fun with local expert, George Riner. Fungi are masters of opportunity. Even after a fire, the spores are in the air and find an environment where the local fungal species – i.e. competition – have been greatly reduced. These may show themselves in ways you may not imagine.

Be prepared for two miles of leisurely walking and chatting over moderate and possibly muddy terrain. Tickets are $10 for adults and $5 for minors. Meet outside the Visitor Center ten minutes prior to the event start time. Please wear appropriate clothing and bring a reusable drink container so your little ones can enjoy hot cocoa after the walk. Heavy rains cancel; parking fees apply.
