About
Overview
Hayden Flat Campground is located 31 miles west of Weaverville, CA along CA Highway 299 at an elevation of 1200'. Located on the Wild and Scenic portion of the Trinity River, this campground is a wonderful place to camp when enjoying all the river has to offer. The upper loop of the campground has been converted into 3 group sites.
Recreation
The Trinity River offers fun-filled hours of fishing, swimming, floating, rafting, kayaking and boating. River access is available at this location for boats that can be carried by hand. Nearby tributaries to the Trinity River offer beautiful spots to swim and spend the day.
Generally, Pigeon Point to Big Flat is too dangerous for tuber and family canoeists. Boating is no advisted from Cedar Flat to Grays Falls except for expert boaters. Several commercial guides operate on the Trinity River under Forest Service Special Use permits. They provide quality guided raft and white water instruction and can be found on the Shasta-Trinity NF website.
**Please note that the Trinity River is subject to periodic changes in flow conditions from releases from Lewiston Dam. Current flows (CFS) can be obtained by calling (530) 246-7594.
