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

It was great! Had to modify dates and the online system worked well. Checked in late and the Staff at
the Lodge were very polite and helpful.
CG was
great and bathrooms were clean and warm.
Rhis is a place to be a base while exploring Grand Teton and Jackson. Close
together but flat and plenty of room for reasoanably sized rigs. NOT for these giant tractor
teailer sized trailers with nine slides

Easy to locate. Easy check in and out. Clean bathroom and shower. Portable water available. Free WiFi available by bathroom, check in area and the lobby of the lodge nearby. The campground is at a perfect location to visit both YellowStone and Grand Teton National Parks if one cannot find suitable campsite inside either parks. We stay at a tent site. It is flat, easy to set up a tent. At the RV site, there are electric hook up that can accommodate level 2 EV charger. A big plus for EV owner.

Great location if you are visiting both Yellowstone and Grand Teton. Spots were close together however still nice. Only complaint was the barking dogs. It was hard to enjoy peaceful fires at night with barking dogs in the campers around us and outside at people's campsites.

Quiet, flat and clean. Spaces are little closer together but for Rv, vans, cab overs it’s no biggie. Sites are all level or near level. Clean bathrooms, and clean showers included in site fees.

The overall setting and staff are 5 stars. I’ve stayed here multiple times, and would definitely stay again.

I gave it three stars for a few reasons I see as places for easy improvements.

1 - we stayed in cabin 101 not realizing it faces the dumpsters, check-in area and main flow of all incoming traffic, which over a weekend is constant. That all devalues it. People staying there do not get the same peace and value as those in other cabins and it should be a discounted price during weekends and peak times.

Additionally, since there was no apparent campground host, guess where everyone arriving late goes? That’s right! Cabin 101!!! We were interrupted 4 separate times in one evening by people needing my to know basic campground wayfinding because signage is so minimal and there are no hosts up front in that spot.

Lastly, the hooks in Cabin 101 and in the closest bathroom all appeared to be ripped off. I hate that guests can’t keep things nice! But having those makes a big difference in functionality.

Place a host prominently up front by check in. Place user-friendly signage. Fix simple things like hooks in cabins and bathrooms. Give guests in 101 a slight discount since that stay is definitely not the same value as others.
