Hayfork Campground (Group Only)
Hayfork Group Campground is a group only site located 49 miles northeast of Boise, Idaho, along scenic State Highway 21. The historic Idaho City is just 12 miles south of the campground. Visitors enjoy fishing in Mores Creek and exploring local trails. Natural Features: The campground is situated at the foot of a ponderosa pine-forested hillside along State Highway 21, at an elevation of 5,100 feet. The campsite, however, is in an open area with limited shade. Wildlife and summer wildflowers are abundant in the surrounding area. Recreation: Mores Creek runs between the highway and the campground, offering cutthroat and rainbow trout fishing. Numerous trails are in the area, providing ample opportunities for hiking, biking, horseback riding and off-road vehicle riding. In the winter, the area becomes a playground for back country skiers and snowmobiles.
