Grayback
Grayback Campground is located 36 miles northeast of Boise, Idaho, just off scenic Highway 21. Historic Idaho City is just two miles north of the campground. Visitors enjoy fishing in Mores Creek and exploring the Grayback Gulch Trail.
The campground contains two group sites with picnic and serving tables, grills, campfire circles and paved site pads. Site A can accommodate up to 150 people and 20 vehicles, and site B can accommodate up to 100 people and 15 vehicles. Both sites can be reserved at the same time, for even larger groups.
Several single- and double-family campsites are available as well, each equipped with a picnic table, lantern post and campfire ring with grill. Vault toilets, drinking water and trash collection are provided throughout the campground. A campground host is located directly across the road.
