We appreciate your patience as we improve your experience for seasons to come and cannot wait to welcome you this summer!

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.  

Number of accommodations: 165

We had a great time at Headwaters - Flagg Ranch. Wish we would have stayed longer!

Fantastic campsite! We stayed in a camper cabin and it was great. Loved the fire pit and picnic table at each site! I also appreciate the laundry room (though we didn’t use it) as well as the bathrooms (always clean and stocked!) I would recommend this site to anyone, I loved it. It’s so close to two great national parks! I will absolutely be coming back in the future.

Awesome little campsite between Yellowstone and Grant Tetons. The lodge was also pretty nice with a convenience store, gift shop, and restaurant. The campground was clean and had free WiFi. We were towards the back and the WiFi was occasionally spotty, but it worked and it was a welcomed amenity. Overall had a great time there!

The campground was nice with the spaces, trees and scenery. Hookup was easy and accessible. The bathhouses were not kept up very well compared to other campgrounds we had stayed at. They needed to be cleaned and attended to. That was the main drawback.

Lovely site, but not really a good choice for a 34 ft RV. About 4-6 inches space on either side of the RV. The removal of 1 small tree on site 106 would make the difference between a difficult and time consuming parking and an easy in and out.

Nice and friendly staff. Clean cabins. Great place to stay for visiting both National parks in one go! Can’t wait to do it again!

We were only there 2 nights so we didn't really get to explore the campground so this review is based on the layout, bathrooms, etc. For the size of the campground, there isn't enough bathrooms or showers. Campsites are basically right on top of each other. So close we could hear the the people snoring in the site next to us. Pricey when compared to area campgrounds. Not sure I will stay again. Clean though and the store is nice.

The campground is in a beautiful area with all the things you need. It is very well kept. The bear boxes are clean and quite large! The bathrooms were clean and the showers were some of the best campground bathrooms I’ve encountered. I would 100% return to this campground.
