Fourmile Cabin

Custer Gallatin National Forest

Fourmile Cabin is open year-round and offers guests a rustic mountain retreat surrounded by majestic scenery. The cabin offers an electric cooking stove, lights, and a refrigerator. Guests will need to bring most of their own gear and supplies to ensure a comfortable stay.

The cabin is accessible by vehicle during warmer months, along a gravel county road. Late-season ice may require guests to snowshoe, hike or snowmobile up to 3.5 miles to the cabin. Guests arriving in winter should be prepared to snowmobile, ski or snowshoe up to 11 miles along the access road to the cabin. Guests are responsible for their own travel arrangements and safety.

The two-room cabin has an electric stove, lights and refrigerator. A wood-burning stove is provided for heat. Firewood is not available from June 1st through September 30th. Please bring firewood or gather from the forest during the summer season. Do no burn provided firewood for outdoor fires ever, as it is extremely difficult to replace. Firewood is available during winter months as long as supplies last.

The cabin can sleep up to four people on provided twin beds with mattresses. Other amenities include basic cookware and utensils, some cleaning supplies, a table with chairs, axe, maul, bucket and shovel.

There is a campfire ring and a vault toilet outside.

Water is not available at the cabin. Guests need to bring their own water supply or be prepared to treat water taken from an outside source. Garbage bags are needed to pack out trash, and guests are expected to clean the cabin before leaving.

Guests should also bring their own flashlight, bedding, cookware, dishes, utensils, newspaper, matches, toilet paper and first aid kit, among other necessities.
