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 totally enjoyed our stay! Great location to see both the Tetons and Yellowstone. Our cabin was basic but did the job. Shower facilities were clean and had great hot water... perfect for after a long day hiking. We went to the restaurant at the lodge and the breakfast was great!!! Tasty biscuits and gravy!
We'll definitely be back.

Sites were not level and sewer hook up pipe was too high to allow for proper drainage.

What a gem of a place to stay. The campground was very clean and welcoming. The staff was fantastic - meeting people and sharing stories from all over the world and Yellowstone! Would definitely stay there again!

Cabin is cozy and clean! Bathrooms and showers areas are clean. Could use some warm water in the dishwashing station, but overall, satisfied.

This was by far the worst campground I have been in for some time. Campsites are extremely tight and if you are a tent camper like me, your head while sleeping is only feet from someone’s vehicle or the road. Campsite staff was rude and unhelpful. The campground is very confusing. We helped multiple people find their way back to their sites. There are roads everywhere and lots and lots of dust. I will never camp here again. I recommend closing this campground.

Very friendly and helpful. The sewer connection was very tall and hard to use. Nice location to both parks.

We were very pleased with our cabin at Flagg Ranch! It was the perfect amount of space for us and held heat really well. The campground grounds and restrooms were kept very clean. And the location was perfect.

We stayed at a cabin site that held a 30ft rv. We didn’t use the cabin, we stayed in our RV. There was no discount from my senior park pass for a cabin, so we just paid it because we couldn’t get reservations anywhere else. It’s located way north of anything to do in Grand Tetons but it’s on the main road. There is a gas/diesel station there and a nice little store. It’s close to the hot springs but we found out two things about that. 1. A long hike crossing a small river up to your thigh. 2. Has bad bacteria that invades your body through skin sores and eyes.
