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

Very nice campground. People were quiet at night and were pretty respectful. The only complaint is the dust. The roads and campsites were very dusty and it got everywhere. We stayed in site 319 and had 3 roads go by our site so there was always a constant stream of vehicles. Otherwise it was very nice and the staff was polite.

Great little cabin, clean, sturdy, warm, bed was a little on the firm side, and showers weren't the best but overall a great spot on our trip.

Wonderful stay! I stayed in a cabin and they really had everything I needed! I brought my own pillow and sheets, but they had a lantern in the room, wifi on the campground, laundry machines, dish washing station, etc. The camp store, restaurant, and gift shop in the lodge about 200 meters away was also very convenient! The cabin was very clean and the campground was very quiet.

Very friendly staff. Nice central location between the two parks. There is a general store across from the campground which allowed us to fuel up and get coffees.
You forfeit privacy for the convenience, as the sites are very close together. We lucked out with our site, it had more grass and trees than other sites which our pups appreciated. I will say that although the sites were too close together for my taste, this park felt like a nature wonderland compared to the two parks we stayed at within Yellowstone!

Overall a great RV campground. Has a small but nice lodge that serves breakfast, lunch and dinner. The Rv area is well shaded and bathhouse's are located close. The cost per night ($150) is high considering it's all gravel roads/parking pads, which makes it very dusty when people drive by even at 5mph. For the cost a road watering truck should be possible or blacktop main driveways. The staff is very courteous and accommodating early arrival. Location is excellent to visit Grand Tetons to the south and Yellowstone to the north. Has a small store and gas station by lodge again expect to pay for convivence ($4.50 for small bag of ice, etc). We enjoyed our stay with the exception of the dust problem, which could be fixed and should be for the price you pay.

We stayed for 7 nights at Flagg Ranch. The campground is in a beautiful area with the Snake River nearby. The restrooms and showers were well taken care of and clean. The staff was friendly and helpful. The only issue was that the roads were very dusty.

Larger clean, well organized campground. Very close to prime fishing locations and Grand Teton National Park and Southern Yellowstone Park. Restuarant on site is amazing as is gift shop and small general store. Gas station has diesel fuel and reasonable prices. All RV sites are level

Very, very dusty! They need so much gravel brought in!!

Lots of trees with good space between spots, so that's nice.

ZERO t-mobile cell service. Camp wifi was spotty at best.

Lodge had gift shop, bar, restaurant and small convenience store with gas pumps ( gas was expensive).
