Great campground between Yellowstone and the Grand Tetons. Appreciated that tent spots were fairly separate from RV sites.

Overall we had a good experience. The bathrooms were the best of any campground I’ve stayed at. The two things that could have been better:
1. Fewer mosquitos (not much that can be done about that, unfortunately)
2. Less dusty - it would have been nicer if the roads in the campground were paved.

Right in the Grand Teton and just 30 minutes from Yellowstone. Location! Campground is rustic and minimal. Bathroom are clean. Full hookups. Price is high for bare bones camping.

Conveniently located between the two parks. Decent cell service. Full hookup and laundry. Small convenience store with gas station across the street. Propane filling.

The tent campsites were too close together and overpriced! We payed for one night but didn't even stay. We left and went to another campground. Susan at the lodge was very helpful with telling us about remote places to see and hike. She gets 5 stars! *****

This location was perfect for what we needed! Although the bed was not comfortable whatsoever (which I expected) I loved the cabin. We forgot to take a few things into the park with us, and the general store had a great selection to help us get by. We wanted to visit both Yellowstone and Teton and this location was perfect. It is maybe two miles to the Yellowstone entrance and at the top of Grand Teton NP, so we got the best of both worlds. We arrived late and it was still easy to check in with no hastle.
