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.
Starting from a forested trailhead near the heart of the 2017 Nuns Fire footprint, this route leads you through open meadows, dense oak woodlands, and along year-round streams—punctuated by seasonal waterfalls and stunning ridge-top vistas. The trail winds through diverse microclimates with notable elevation gain and a shallow water crossing (conditions vary with rainfall), making it ideal for experienced hikers looking for a unique experience off the beaten path.

What to Bring:
— Sturdy hiking shoes
— Ample water and trail snacks
— Weather-appropriate layers and sun protection
— Trekking poles if preferred for uneven terrain
There is no charge for this outing, which is made possible by the voters of Sonoma County who fund the work of Ag + Open Space with a quarter-cent sales tax.
Space is limited and registration is required. Don’t miss this chance to experience one of Sonoma County’s most secluded and spectacular preserves in the heart of the Valley of the Moon.
