Equinox comes from the Latin words for equal night. As autumn begins, please join Sonoma Ecology Center naturalists on an exploration through the Calabazas Creek Open Space Preserve.

This is the first year since the Nunns Fire that guided hikes led by SEC staff have been allowed. The preserve is only accessible to the public on guided outings and is known for its stunning vistas, open meadows, waterfalls, and oak woodlands. Calabazas Creek provides hikers with a multitude of microclimates as well as a rigorous hike. Bring along friends and family, and a picnic lunch to enjoy with us!

The Calabazas Creek Open Space Preserve was protected by Ag + Open Space in October of 2004 for recreation and preservation of its natural resources, including the stretch of Calabazas Creek that cascades down the canyon. The 1,290-acre property, overlooking the Valley of the Moon, is one of the most exquisite natural sites in Sonoma Valley, containing a wide array of habitats.

This is a strenuous hike with substantial elevation gain on established trails. Please bring water and lunch, and be prepared for that day’s weather. There is a shallow water crossing. The hike will go on in light rain, but heavy rain will cancel the outing. 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.

REGISTER TODAY! Reservations are required online by 5pm on Wednesday, Sept. 18. Directions and day-of contact information will be emailed upon registration. For more information or questions, contact Tony Passantino at (707) 996-0712, ext. 124 or
