Team Sugarloaf started in 2012 as a partnership of five non-profit organizations, led by Sonoma Ecology Center, dedicated to the natural resources of Sonoma Valley and to providing access to the natural haven of 3,900 acres provided by Sugarloaf Ridge State Park.
Today, Sugarloaf Ridge State Park is operated solely by Sonoma Ecology Center. While Sugarloaf is a California State Park, we do not receive operating support from the State. It is our supporters, visitors, and members that keep Sugarloaf Ridge State Park open to the public. If you haven’t already, please consider supporting the park with a donation.
