Sugarloaf Ridge
State Park

"Team Sugarloaf" operates Sugarloaf Ridge,
including the campground. Five nonprofit organizations formed a unique partnership that has worked tirelessly to keep our park open.  

Partners are: Sonoma Ecology Center; United Camps, Conferences and Retreats; Valley of the Moon Natural History Association; Sonoma County Trails Council; and Valley of the Moon Observatory Association.  

With expertise in campground operations, ecological restoration, astronomy, trails management, and volunteer recruiting and training, Team Sugarloaf is creating new opportunities for Sugarloaf Ridge and its visitors.  Visit sugarloafpark.org for more information.

Come to stargaze and camp at Sugarloaf Ridge!
