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!

Great News! The park is open for camping and hiking and recovering well from the Glass Fire!

Hiking:  Most trails are open and the flowers are in full bloom.  Goodspeed Trail, part of Brushy Peaks Trail, and all trails in the McCormick Addition remain closed due to the Glass fire. 

Park Day Use Hours: 6:00am-10:00pm

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!

Creek Camp at Sugarloaf Ridge State Park @ Sugarloaf Ridge State Park
Jun 21 @ 9:00 am – Jun 25 @ 3:00 pm

Join us for a week (or two!) of Creek camp exploration at Sugarloaf Ridge State Park. Traverse the headwaters of Sonoma Creek Watershed in this recreational and environmental education camp. Campers will spend the week as explorers, starting off the day with morning hikes on the park’s trails. As the day warms, we’ll stay close to water, exploring the creeks for insects and amphibians. Activities include investigating the properties of water, collecting and studying aquatic insects, learning about the wildlife and plants found in the park. Our camp days will also consist of plenty of games, hiking, and storytelling.

 

Creek Camp is run by Sonoma Ecology Center naturalist Jonny Ehlers. Jonny is a fourth-generation educator who began working with youth right out of high school in an after-school program in Sacramento. He later became an educator in West Sonoma County at a residential camp working with diverse populations and founded The Mycelium Project, an organization dedicated to helping kids and adults through hikes, and nature-based activities. 

 

*We look forward to joining together in person and engaging with youth once again, off-screen and in-nature. However, given the uncertainties of our public health guidelines, our camps will be continually evolving. We will abide but whatever our scientists and medical experts deem as safe for in-person meetings when the camps start this summer. At this time we are limiting the sign-ups for this camp to no more than 12 participants.

6/21 Creek Camp 8-12, 9-3pm

Sugarloaf’s PPPP (Personal Porta Potty Program)

 Each campsite has its own porta-potty which our dedicated campground Staff cleans between each set of campers.  “The feedback from campers has been overwhelmingly positive”, said campground manager Woody Woodbury. “They like the safety as well as the convenience of having a toilet near their site,” he continued.

  • Some Cool Finds During City Nature Challenge
    City Nature Challenge is an international event that takes place on the same weekend each year to encourage scientists and citizen scientists to document on the iNaturalist app any and all species they see in nature. Team Sugarloaf has participated in it for the past several years. Last year the pandemic interrupted a continuous run, and managers of Sonoma Ecology Center— which manages Sugarloaf—gave careful consideration to participating this year. “This year we decided to go whole hog with it,” says Dr. Dan Levitis, Community Science Coordinator. And they were rewarded with several incredible finds. In a remote northern part of the north side of Mt. Hood, a dozen naturalists spread out in teams to observe parts of the McCormick Addition of Sugarloaf Ridge State Park that burned in the 2020 Glass Fire.  “It burned quite hot last fall,” Dan says. “We found a lot of damage, but a ton of biodiversity coming back, including plants we hadn’t seen in a long time; fire followers, and some things that were not previously documented in the park.”… Read more »
  • Honoring Earth, Honoring Volunteers
    Sonoma Ecology Center and our illustrious, dedicated volunteers help us honor Earth every day, and we’d like to thank them for helping us take care of little patches of our planet right here in Sonoma Valley. In partnership with One Tree Planted and Simply Solar, volunteers and our restoration crew helped clear out invasive broom plants on Sonoma Creek. Scotch and French brooms were introduced in the 1800s and grow well here, so much so that they choke out native plants. When they die they create fire fuel ladders that are highly flammable.  Over at Nathanson Creek another great crew led by Sonoma Ecology Center’s “Earthling” teen volunteer group cleaned up trash and learned about pollinators, plants and ways to protect our planet. Our trail restoration work at Sugarloaf Ridge State Park continues with volunteers repairing steps and bridges, clearing debris, installing signs and generally taking care of the park’s trails. Large portions of Sugarloaf burned in 2020’s Glass Fire, and other portions — some overlapping — burned in the 2017 Sonoma Complex Fires. With… Read more »
  • A message from NEST student, Alexandra Huerta
    As someone who has always admired the grandeur of the outdoors and has an ever-present curiosity for exploring, understanding and preserving our natural world, studying environmental science just made sense. As a Southern California native, my summer days as a youth were full of salty hair, sun kissed skin and bare feet whenever possible. My pursuit of higher education took me to Penn State, where I was surrounded by an entirely new population of research driven, hard-working classmates. My time at Penn State not only offered me a well-rounded education, but it also gave me the opportunity to experience beautiful changing seasons, meet people from completely new and different walks of life, and taught me the value and importance of a sense of community. After graduating from Penn State, I moved back to California, eventually finding my way up the coast to Sonoma Valley. Sonoma has so much to offer us, teeming with natural beauty that we are able to appreciate all thanks to efforts from local conservation groups, local agriculture that provides us with farm fresh food… Read more »
