Description : This small primitive campground is nestled in a thick mixed conifer forest approximately ¼ mile below Castle Lake. There are 6 sites with tables, fire rings and vault toilets. Bring your own water. 3-night limit. No fee. No reservations. Not recommended for large vehicle or trailers. Usually opens around the end of May depending on when the snow melts, and usually is closed by snow around the first of November. Features : Visitors may walk or drive the short distance to the lake. Castle Lake is a pristine glacial cirque lake with granite cliffs and clear water, one of the most popular attractions in the Mt. Shasta area. Hiking, swimming, fishing, and flat-water kayaking are favorite activities here. There are a few hiking trails to explore including the short and easy Shoreline Trail on the west side of the lake.

Special note about Castle Lake

Please be aware that Castle Lake is partially situated on private property.  The traditional trail to Heart Lake and Little Castle Lake leaves the east end of the parking area and ascends to the divide above the east side of the lake. It begins on public land in section 24 of T39N R5W but immediately crosses the boundary of section 19 of T39N R4W. This entire section of land (about 640 acres) is privately owned property and posted as such. There is no legal access across this section to these lakes. Please be respectful and avoid trespassing. However, the west shore of the lake is public and features a short trail with easy access to the water.
