Friends of Trione-Annadel is the official nonprofit fundraising partner for Trione-Annadel State Park via a cooperative contract with California State Parks.

Friends of Trione-Annadel was created in September 2017 in response to the increasing maintenance needs of a highly used recreational area. Trione-Annadel State Park has over 45 miles of official trails and hosts 12-13,000 people per month of all types - hikers, mountain bikers, runners, equestrians, bird watchers, and more.

To support the preservation and maintenance of this unique natural resource, Friends of Trione-Annadel was formed with the intent to protect park resources and deliver a high-quality visitor experience. Friends of Trione-Annadel will raise funds, foster partnerships, and orchestrate projects on behalf of Trione-Annadel State Park. Approved by the California Secretary of State in September 2017, we are an independent 501(c)(3) nonprofit (EIN 82-2686083).

Trione-Annadel State Park does not benefit from Measure M, which solely supports regional and city parks. The park is funded and operated by the California State Park system, which faces increasing budget pressure. Unlike most state parks, which collect a user fee for public access, our community enjoys free access to Trione-Annadel State Park via several open trailheads. Only a small percentage of park users contribute funds to support the park.

Join us! Every donation makes an impact. Friends of Trione-Annadel is a 501(c)3 nonprofit organization run by a dedicated volunteer board of directors. Please help us preserve all the good nature in Trione-Annadel today. Donate or mail your tax-deductible donation to: PO Box 1011, Kenwood, CA 95452.
