Headwaters Campground at Flagg Ranch is a well-maintained facility conveniently located between Yellowstone and Grand Teton, making it an ideal base for exploring both parks. Visitors appreciated the clean amenities, friendly staff, and additional features like a gas station, store, and free showers. However, some campers noted high prices at the store and close proximity of sites, which could lead to noise and lack of privacy. Overall, many expressed a desire to return due to the campground's positive aspects.

You don't want to stay here if you are a senior. They have the billing setup so as to cut your discount in half. They charge you $50 per night for electricity and $50 a night for camping. They don't have to give you a discount on the electricity so they charge $50 for it when there is no way to use more than $5 for one day. It's a scam. Tried to alert Recreation.gov but no one cares enough to do anything about it.

Our family really enjoyed tent camping at Flagg Ranch. The facilities were nice for a campground and the staff did a nice job keeping the bathrooms clean. The campground was generally quiet with minimal traffic rolling past our site. The location of the campground was perfectly situated between Yellowstone and the Grand Tetons. The only knock, and this is a minor thing, is that the campground roads were a little dusty. But is is a campground, so what do you expect. It didn’t detract from the experience, just something to be aware of if you leave things out to dry. Overall, we were very pleased and would certainly recommend and return in the future.

The location between grand Teton Park, and Yellowstone was outstanding. Being along the snake river was awesome. Quite a few mosquitoes due to the time of the year I would highly recommend the horseback riding, the guides for fun and very knowledgeable about the surrounding. Nice trees in between sites with full hookups but the road are little dusty. The bathrooms were clean and plentiful. The store had a good supply of necessities and the restaurant meal was excellent. We had a mechanical issue, and the maintenance person was extremely helpful in assisting us. I would recommend Headwaters
