Sugarloaf Volunteer Trail Crew @ Sugarloaf Ridge State Park
Feb 22 @ 9:00 am – 1:00 pm

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. a backpack). Wear long pants, boots or sturdy shoes and sunscreen. Long sleeves are recommended 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.
Not a Sugarloaf volunteer yet? RSVP to sugarloafvolunteer@sonomaecologycenter.org no later than the Sunday prior to the work day to ensure we have lunch for you.
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.

Join Certified CA Naturalist John Lynch and Sugarloaf staff Desi Harp on a 3 mile, 2.5 hour guided nature walk from creekside to hillside and back through the meadow.

Tickets are $15-$20 sliding scale for general audiences, $7.5 for youth (12-17 year olds) and students, Sugarloaf members, Sugarloaf volunteers, and free for children under 12. Meet at the Visitor Center. Wear appropriate clothing and footwear for two miles of leisurely walking and chatting over moderate and possibly muddy terrain.

Ease of access: The main parking lot has one van-designated parking spot and an accessible vault toilet. There is a paved road from the main lot to the Visitor Center. The Creekside Nature Trail is ADA-compliant compliant for 0.35 miles and then turns into a single-track trail that crosses a narrow cement bridge. Hillside Trail is a fire road with two hills and a water crossing with a board. Meadow is also a compacted gravel fire road. From its trail head to the bridge, although not ADA-compliant, it is a fairly flat trail passable by power chair and stroller.

Mushroom Hike at Sugarloaf (Sold Out) @ Sugarloaf Ridge State Park
Feb 24 @ 10:00 am – 1:00 pm

Explore the hidden world beneath our feet on this mushroom hike led by local mycologist George Riner. We’ll observe their growth, learn to identify different species by key traits, be mesmerized by the display of colors, shapes, textures, and discuss these remarkable organisms’ ecological roles, culinary delights, and even a touch of folklore.

Be prepared for two miles of leisurely walking and chatting over moderate and possibly muddy terrain. Please be aware this is not a foray; collection is permitted for this activity through a CA State Parks Scientific Research and Collecting permit. Tickets are $10-$15 sliding scale for the general public, $5 for students, youth, Sugarloaf members, Sugarloaf volunteers, and free for children under 12. You must have a ticket to attend.

We invite you to bring a reusable drink container so your little ones can enjoy hot cocoa after the walk, if desired. Heavy rains cancel; parking fees apply.

Ease of access: we’re unable to determine the ease of access for this hike as the route will be chosen day-of by the leader dependent on weather conditions and other logistics.

Habitat Hike: Chaparral @ Sugarloaf Ridge State Park
Feb 25 @ 9:00 am – 11:00 am

What is a habitat? Join CA Naturalist and Sugarloaf docent Marie Kay Hansen through the featured habitat, chaparral, to explore all it has to offer. Learn about the largest native plant community flora in California, characterized by rugged terrain and adaptive flora, during this 2-3 mile hike along Goodspeed Trail up to Pierson Rd and possibly past until the unnamed creek crossing. This hike is the first in our four-part ‘Habitats of Sugarloaf’ hike series. Other hikes will explore the oak woodland, meadow and redwood forest habitats.

Meet at the Goodspeed parking lot. Tickets are $10 for general admission, $5 for youth (12-17 year olds), students, Sugarloaf members, Sugarloaf volunteers, and free for children under 12. Wear layers, appropriate footwear for muddy and/or slippery trails, bring at least a quart of water, sun protection, and if desired, a snack. Heavy rain cancels. Parking fees apply.

Ease of access: Goodspeed Trail is an out-and-back, single-track dirt trail. The first several hundred feet is a rough foot trail down to Sonoma Creek. The next several hundred feet (including wooden bridges with handrails over two creeks) is mostly flat. The remainder of the route is mostly steep with steps and a rugged climb through serpentine chaparral.
