Join Sugarloaf docent Susan Perkins in a geology hike to learn about more 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.

Meet at the White Barn parking lot. Tickets are $10 for general audiences, $5 for youth (12-17 year olds; must be accompanied by a parent or legal guardian), students, Sugarloaf Members, Sugarloaf or RFO volunteers, and free for children under 12. 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. Heavy rains cancel. Parking fees apply.
