Headwaters Campground at Flagg Ranch

We like the location, full hookups, and helpful staff. Dusty or muddy roads could be improved in campground. Better ventilation in shower houses would improve user experience and reduce maintenance.

In the heart of Grand Teton National Park!!! What else needs to be said!

Such an amazing experience! Perfect location and great facilities.

I did not have a reservation and they were able to accomadate me with a tenting spot. However, because I am a light sleeper, the #114 campsite was unsatisfactory due to its location within 100ft of a noisy Rt 191. The campgrounds were very clean and the staff was friendly. I ended up using their showering and laundry facilties, thanked the staff for the service and found a dispersed camping site, Grassy Lake road (NPS.GOV) campsite, within a mile of the Flagg ranch campground. I slept well at the confluence of Pole cat creek and the Snake river.

Spent two nights at the Headwaters Campground at Flagg Ranch. Enjoyed walks around the campground and two evening meals at the Sheffield's restaurant in the lodge. Our main objective was relaxation, so we did not take any extended hikes or other activities. Restrooms were clean and the campground was pleasant.

Glamping at its finest! Our campsite was walking distance to the bathrooms, the general store, and the BAR... that was an unexpected treat as a first-timer here! I love the Tetons so much, and camping at Flagg Ranch made it so convenient and comfortable. I would absolutely camp here again!

The campground sites were nicely spaced and we appreciated that the area was rustic and not paved everywhere. On site services like fuel and a few grocery items was appreciated for our adventuress both into the Tetons and Yellowstone as we used Headwaters as a base for both National Parks. Unfortunately there was a camper a few sites down from us who chose to pull out a large chainsaw at 9pm and proceeded to cut down a dead tree for firewood right in the campground! UGH . Apparently there are not onsite camp hosts or anyone watching out for this "illegal" behavior .. It is in the rules and regulations of this park that this is unlawful behavior. I called 911 and reported this and the incident was forwarded to dispatch. Sad .. the offensive campers were from Texas.. guess they think this kind of behavior was ok. They were not happy that I reported them . They were not in that site a day or 2 later . Otherwise the campground had nice hiking trails where we could walk to the nearby river for a lovely couple of evenings. The shower house was kept clean. The price per night certainly was high.. but I guess thats the way things are for Yellowstone camping these days

I was in site 523 for 8 days. It had broken tree cover (partially obscured Starlink) and I had 2 Bars (5g) on Verizon. The 30A electrical Outlet worked fine. The Dump tube on the site is like 18" above the ground, which put it above the bottom of my black tank rendering it unusable without making a big mess. There is no separate Dump on site at Flagg Ranch, but they are the same company as Colter Bay Campground, which does have a dump you can use for free. It was a pretty campground, but the sites are fairly close together. Most folks make camp fires, which made my RV smell like smoke if I had a window open in the evening. The gas station has a few groceries, but you will need to drive to Colter Bay if you want a full grocery store. There is an on site restaurant which was above average.
Great access to both Yellowstone and Teton, although you will be driving a fair bit to either one.

We really enjoyed eating at the Headwaters restaurant. We were waited on by Radesh(?) from Romania for the second year in a row. He’s very friendly and good at his job.

Bathhouse was clean, had hot water and good water pressure. Sites were level. Staff was great. We booked on short notice and they were accommodating!
