Small cabin - double bunk, small 3-drawer dresser, and table/chairs. No electricity, but there is a small battery powered lantern. Outside had fire ring and picnic table and a small porch that spans the front of the cabin. Not too far to restrooms / showers/ dishwasher station. Road noise was a lot less than I expected based in location. Would stay here again. Note: Cabin to the left while facing door is really close. If needing space for more than 4 or need two cabins, these would be great options!

Easy checkin at Main Lodge. Small end spot. Backing best although if picnic table was moved slightly might be a good pullthrough for smaller camper. No hookups at this particular spot, but beautiful views of the Tetons. Not too far to walk to restrooms/ showers/ dishwasher station. Bear box included for food. Fire ring with cooking grate.

Great place to stay. Very close to the south entrance of Yellowstone NP. Cabin was clean and stayed cool during the day for a good nights sleep. The only reason I did not give 5 stars is paper towel dispensers in the bathroom's were not filled and the fire rings need some work.
