Volunteer: 9/2025 - 12/2025 - Docents Needed! Sunset Moonrise Hike SupportWe are requesting at least 2 docents/sweeps that can hike at a reasonable pace to help folks get up the hill at Coyote Valley for our first Sunset Moonrise Hike Series!
Bonus points - a beautiful view to enhance your meaningful time. Sign up for one or all! Please note the times have changes for October, November, and December hikes. Program Description for the Public Take an unforgettable evening adventure on a guided 4-mile Arrowhead Loop Trail at Coyote Valley Open Space Preserve. We will leave when the light is golden and the grasslands are alive with birdsong. As we ascend toward the ridge, this gentle climb offers sweeping views of the Coyote Valley and surrounding foothills. Once we reach the top, settle in to watch nature’s double feature: the sun sinking below the Santa Cruz Mountains in one direction, and the moon rising over the Diablo Range in the other. The transition from day to night is quiet and magical here. After dark, we begin our descent under the moonlight. With headlamps or flashlights in hand, we will follow the trail down through oak woodlands and open meadows. It’s peaceful, a little thrilling, and a completely different way to experience a familiar landscape. Bring water, layers, a flashlight or headlamp and maybe a thermos of something warm. Times will vary on this hike series so check our calendar for departure times. Program: Interpretive Docents We are requesting at least 2 docents/sweeps that can hike at a reasonable pace to help folks get up the hill at Coyote Valley for our first Sunset Moonrise Hike Series!

Volunteer: 2025 Trail Patrols in Open Space Authority PreservesWe welcome Open Space Authority Volunteers to respond to this request for ongoing support in our preserves. Trail Patrol Volunteers serve as agency ambassadors, greeting all members of the public in our preserves. Volunteers should complete these activities between the hours of sunrise and sunset in one of three preserves: Sierra Vista OSP, Coyote Valley OSP, and Rancho Cañada del Oro OSP. Please wear an Open Space Authority branded volunteer shirt, a name tag, and appropriate footwear. The goal is to engage other guests and improve their experience, we do not need volunteers to enforce rules. Rather, please report activities that are outside the guidelines for visitation in your hours reports so that staff will be able to review and respond appropriately. For staff contacts and guidelines on engagement, please see the Volunteer Resource Guide linked on the Volunteer Resource Page in the sidebar menu. Trail Patrol volunteers should not go to Máyyan Òoyákma Open Space Preserve to complete patrols, as we have a distinct volunteer role in that preserve to support this function, called 'Preserve Steward support at Máyyan Òoyákma'. If you are interested in supporting that effort, please contact Teri Rogoway. Please note that trail patrol opportunities expire on a yearly basis, this one will expire on Dec. 31 2025.
