About Mccain Cabin
Overview
McCain Guard Station is a rustic cabin that is popular year-round. In summer, hikers and horseback riders frequent the cabin, and snowmobile enthusiasts make use of the cabin throughout the winter. Several trails are nearby, and the open meadows offer gentle sledding for younger riders. Winter access in by snowmobile only on a groomed trail.
Constructed in 1933 by the Civilian Conservation Corps (CCC), the cabin welcomes guests to experience the rustic getaway with impressive scenery.
Recreation
Numerous creeks and the Little Greys River meander through the area, offering fishing opportunities. Hiking, biking, horseback riding and off-road vehicle trails are also in the vicinity. This includes Big Springs Trail and the 9-mile Bailey Creek Trail along a portion of the designated Wild and Scenic Snake River Headwaters. Motorbikes are allowed on nearby Telephone Pass trail from 7/1-9/10.
Facilities
The nonelectric two-room dwelling fits six overnight guests and no additional guests may camp outside. A vault toilet, picnic table and fire ring are located outside behind the cabin.

No water is available, and dishes, pots, pans and utensils are not provided. Recommended items to bring include drinking water, garbage bags, dish soap, dish towels, toilet paper, a flashlight, sleeping bags and pillows and cleaning products such as bleach or disinfectant.
Natural Features
Nestled in a mountain valley at 6,900 feet in elevation, the cabin is perched near a creek that flows into Little Greys River. Pines line the hillsides, but no trees are near enough to offer natural shade to the cabin complex. Deer, moose, elk, eagles and sandhill cranes are among the wildlife likely to be seen. An abundance of wildflowers color the landscape in summer. The Bridger-Teton National Forest offers more than 3.4 million acres of public lands for outdoor recreation. With its pristine watersheds, abundant wildlife and immense wildlands, the forest comprises a large part of the Greater Yellowstone Ecosystem, the largest intact ecosystem in the lower 48 states.
Nearby Attractions
