Summit Saturday: Calabazas Creek Open Space Preserve (formerly called the Hidden Gem Hike)

If you’re drawn to dramatic landscapes and hidden corners of Sonoma Valley, this hike is for you. Join Sonoma Ecology Center for a guided, moderately strenuous exploration of Calabazas Creek Open Space Preserve, a 1,290-acre protected gem nestled in the Mayacamas Mountains and shaped by both time and fire. This special outing, in partnership with Sonoma County Regional Parks and the Sonoma County Agricultural Preservation and Open Space District, offers a rare chance to traverse a preserve still closed to regular public access.
