WHY WE EXIST
Friends of Trione-Annadel was created in September 2017 in response to increasing maintenance needs of a highly used recreational area which continues to experience declining public funding.
Trione-Annadel State Park hosts 12-13,000 people per month of all types - hikers, mountain bikers, runners, equestrians, and more. The park has over 45 miles of official trails. Due to State budget cuts, the park relies heavily on volunteers to maintain the trails. Read more
PROJECTS & UPDATES
With support from many generous donors, Friends of Trione-Annadel has funded numerous projects benefiting the park. Recent projects included the installation of 17 new Kiosks (donated by the Trione family) throughout the park and the completion of repairs to the dam at Lake Ilsanjo.
Our goals for 2020-21 include supporting completion of approved trail work on Channel, Two Quarry, and Lawndale trails and educational opportunities for grammar school programs throughout Sonoma County.
