Named the Gateway Trail because it offers access to the forest from town, the shared-use trail is open to mountain bikers, hikers, runners, dog walkers, and equestrians. The Trailhead and parking lot are nine-tenths of a mile past the Mount Shasta High School on the right of Everett Memorial Highway.

The system curves up the lower flank of Mount Shasta through open brush fields and conifer plantations and offering superb views of the Eddys, Castle Crags, Black Butte, and Mount Shasta. The Gateway Trail interconnects with other trails and roads providing about 10 miles of single-track and 10 miles of dirt roads for one to five hours of riding depending on route selection and ability.

Greenhorn Park is one of the most beautiful and well used recreation areas in all of Siskiyou County. The newly signed trails offer hours of great mountain bike riding. Host to the Humbug Hurry-Up and many other local sporting events, Greenhorn is sure to have what you are looking for in outdoor recreation.
