Shannon Campground

US Forest Service campground. Shannon Campground is small and tucked away along the upper reaches of Marijilda Creek, a pleasant little brook that winds through a setting of tall trees and green grass. Campsites are shaded under mature Engelmann spruce and Douglas-fir. Two three-sided wood shelters of the type originally developed in the Adirondack Mountains of New York add to the historic atmosphere of this campground. The Arcadia Trail, which leads down the mountain to Arcadia Campground, has been designated a National Recreation Trail. A one-mile spur leads from this trail to the top of Heliograph Peak, a vantage point with a history as well as a view. This 10,022-foot vantage point once served as a location for signal mirrors used to communicate messages during the Apache Wars of the late 1880s. Today you'll find a Forest Service lookout tower on the mountaintop as well as some of the most panoramic views in southeastern Arizona. Note: Vehicles (including trailers) longer than 22 feet are not recommended because of the difficulty of negotiating the switchbacks on AZ 366. Campground restrictions: Pack and saddle stock are not permitted in campground. Limit 2 vehicles and 10 persons per site. 14 day stay limit. Black bear area. Store and dispose of all food in bear-proof containers and trash bins, or keep it locked in your vehicle with windows all the way up. Not reservable through Recreation.gov, so plan on first-come, first-served; check with the ranger district for current conditions and fees.
