About Headwaters Campground at Flagg Ranch

Availability will go live on Recreation.gov on a 6-month rolling basis for RV sites, Tent sites, and Camper Cabins.   Located in the John D. Rockefeller, Jr. Memorial Parkway, directly between Grand Teton and Yellowstone National Parks and just minutes from both, Headwaters Campground offers the perfect basecamp for exploration. Situated in a spectacular wooded setting with rolling hills and Teton mountain views, this campground is the perfect place to unwind and unplug, as there is limited cellular or internet service. Commune with nature and spot bear, moose, mule deer, and more as you stroll along nearby Polecat Creek. For avid anglers, the Snake River offers plentiful cutthroat trout, brook trout, and whitefish. While none of Headwater’s campsites are on the river, all are within walking distance.    The campground offers 34 tent sites, 97 full-hookup and pull-through RV sites, and 40 Camper Cabins, and is open from June to October. Visitors are encouraged to plan ahead and book early.

Summary

AI generated

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.

I stayed down the road a few miles and hardly a mosquito. Headwaters must have imported them. It was horrific and everyone at the campground was covered head to toe at every minute. Hundreds of campsites, hundreds of people being attacked because there is absolutely no concern to spray the area to make the paying customers happy. It's dusty as well, but I'd take 20x the dust if they would get rid of the mosquitos. The 2 stars is for the closeness to the South entrance of Yellowstone.

Wonderful base camp for Yellowstone. South Entrance is just 2 mi away. Situated on the Snake River in Lodge Pole Pines. We had site 304 and it was fine, but wished we would have gotten one on the back side, (500s and 600s) with more trees and opening onto the meadows down to the river. Sites are closer together than it looks like on recreation.gov. Definitely prepare for mosquitos, but this can change each season and time of year of course. Wonderful walk/bike down closed road to Pole Cat Creek and Huckleberry Springs. Just beautiful! Only complaint and this is because we were on a two week road trip and needed the laundry amenity. Highway robbery at 5.25 a wash load and 3.25 a dry! Quarter machine was broken and front desk at the lodge didn't have quarters either. Did a nice horse back ride as well. The little and bigger cabins look great, many with wonderful views. Lodge has a restaurant and bar, we didn't use but look cute. Gas station with wood, ice, and everything else you might need. Would stay again.

We stayed almost a week. It was fantastic. This was our second trip to the Tetons and stayed at Flagg Ranch CG. I wouldn’t stay anywhere else.

Wonderful base camp for Yellowstone. South Entrance is just 2 mi away. Situated on the Snake River in Lodge Pole Pines. We had site 304 and it was fine, but wished we would have gotten one on the back side, (500s and 600s) with more trees and opening onto the meadows down to the river. Sites are closer together than it looks like on recreation.gov. Definitely prepare for mosquitos, but this can change each season and time of year of course. Wonderful walk/bike down closed road to Pole Cat Creek and Huckleberry Springs. Just beautiful! Only complaint and this is because we were on a two week road trip and needed the laundry amenity.
