Sugarloaf Through the Ages

Redwoods hike at Sugarloaf Ridge Park
Sat, February 15, 2025, 10:00 am - 12:00 pm

Join Sugarloaf docents Jim Sickles and Susan Perkins in a geology hike to learn about the geological formations that give Sugarloaf Ridge State Park its namesake, how soil composition influences native flora to thrive, and take a lightning-fast journey (in geological terms) through the history of the area, from the time California was underwater to today’s volcanic caldera remains.

Tickets are $10 general, $5 for students, youth, Sugarloaf members, Sugarloaf volunteers, and free for children under 12. Meet at the main parking lot. Wear layers, appropriate footwear for muddy/slippery trails, bring at least a quart of water, and if desired, a snack, binoculars, and/or a camera. We invite you to bring a reusable drink container so your little ones can enjoy hot cocoa after the walk, if desired. Parking fees apply.

Ease of access: The main parking lot has one van- designed parking spot and one accessible vault toilet. Canyon Trail has two trailheads, with the upper trailhead about ½-mile from the main parking lot, on Adobe Canyon Rd. Canyon is a steep trail with about 120 built-in steps and a descent of approximately 450ft to the detour of Sonoma Creek Falls. Skipping the detour, Canyon Trail continues as a fairly flat trail adjacent to Sonoma Creek with two narrow wooden bridges and about 13 steps uphill to the lower Canyon trailhead on Adobe Canyon Rd. A few yards uphill, across the road, the lower Pony Gate trailhead continues uphill for over a mile, including a water crossing with a board and approximately 450 ft elevation gain until it reaches the upper Pony Gate trailhead(s), either across from the Upper Canyon trailhead or by the entrance kiosk, ¼-mile from the main parking lot.
