Since 1990, we’ve worked to increase appreciation and stewardship of Sonoma Valley’s natural heritage and create measurable benefits in areas of land, water, climate change and biodiversity. Supporting our work enables us to move us all towards a better future.

Who We Are

Sonoma Ecology Center works to address challenges related to water supply and quality, open space, rural character, biodiversity, energy, climate change, and a better quality of life for all residents.


We envision a future where people, land, water, and wildlife thrive.


Our mission is to work with our community to identify and lead actions that achieve and sustain ecological health in Sonoma Valley.

How can people, land, water, and wildlife thrive in a fire-adapted landscape?

Creekside Nature Hike @ Sugarloaf Ridge State Park

Every Saturday between Memorial Day and Labor Day, join us for a 1.4-mile nature hike along the Sonoma Creek. On the hike your leader will teach you about the plants, animals, and aquatic life of Sonoma Creek. This free hike starts outside the Visitor Center. Registration is not required. Parking fees apply.

Full Moon Hike @ Sugarloaf Ridge State Park | Kenwood | California | United States

Bring a flashlight and your sense of wonder as you explore the park after dark. This hike begins at the White Barn and heads up to Bald Mountain, where we will see the moon rise over the Mayacamas and the sun set over Sonoma Valley.

This route is a strenuous 6.5 miles with 1500+ of vertical and some steep sections (not recommended for children under 12). It leaves the White Barn parking lot at 6:30 p.m.

Tickets are $10 general, and $5 for youth (12-17 year olds; must be accompanied by an adult), students, Sugarloaf members, and Sugarloaf volunteers. Be at the meeting location at least 15 minutes prior to the start of the hike for a prompt departure. Bring at least a quart of water, snacks, your flashlight, and extra layers for the evening. Parking fees apply.

For more events at Sugarloaf, visit our calendar.


Volunteers play a crucial role at keeping Sugarloaf Ridge State Park open and accessible to all! Help Sugarloaf with trail restoration work by coming to our every-other-Thursday Volunteer Trail Crew. Activities include bridge and step construction, installing signs, clearing, lifting, carrying, and hiking.

Bring gloves, hat, and water that you can carry hands-free (i.e. bring a backpack). Wear long pants, boots or sturdy shoes and sunscreen. Long sleeves are suggested as poison oak is present. We have tools and trained crew leaders with tasks for all. Minors must be accompanied by a responsible adult. We will provide tools, and if allowed, lunch.

If you are a current Sugarloaf volunteer, log onto Better Impact to sign up. First-time volunteers are welcomed and encouraged to formally join our volunteer program if they’d like to support us more frequently. Start here to become a volunteer.

Sugarloaf Ridge State Park Community Works to Transform Sugarloaf into a More Accessible Space

The community at Sugarloaf, which comprises of staff, volunteers, and visitors understands that there is more to be done to make Sugarloaf a place that truly serves the diverse needs of those who frequent our park. Ongoing efforts to make Sugarloaf more accessible have been a collaborative endeavor between Sugarloaf staff and the community we serve. Using a grant from the National Environmental Education Foundation, Sugarloaf staff are working with Judy and Bonnie to assess the conditions of the park and create a plan on how we can make the park more accessible for hikers with limited mobility.
