Sign up for Volunteer Training -- Class of Spring 2015

California State Parks will be recruiting new volunteers with a love of nature, enthusiasm, and an interest in developing their knowledge of the outdoors to join the Portola-Castle Rock volunteer team. If you would enjoy interacting with park visitors and have a minimum of 6 hours per month to give, become a volunteer! Training takes place Saturdays  from March to April. Attendance at all (four) sessions is necessary; with an additional optional two days in April to hike the parks with staff to get to know the trails and infrastructure. For registration information, please send a short email to:

With the help of the Portola and Castle Rock Foundation, California State Parks has established a volunteer program for both Castle Rock and Portola Redwoods State Parks. Volunteers are quickly proving themselves to be vital to sustaining the livelihood of these parks. In 2013, the first year of the new program, the volunteers in Portola Redwoods State Park and Castle Rock State Park donated over 1600 hours. Their presence has been felt on the trails, in the Portola Visitor Center and around the rocks at Castle Rock.

Castle Rock State Park is a rock climbing, hiking, and backpacking open space park. Portola Redwoods State Park is traditional camping and hiking park.

Those that apply will be asked to include a one or two paragraph short biography to introduce yourself and why you are interested in becoming a volunteer in either Portola Redwoods or Castle Rock State Park (or both). Accepted registrants will receive confirmation that they are registered, and before the training itself, will be interviewed. Interviews are ideally done in person, but may also be done over the phone.
