I've stayed at Flagg Ranch/Headwaters Lodge many times. It's a great location right between the North exit of Grand Teton and the South entrance to Yellowstone. The rooms are very comfortable and clean. The staff is always accommodating. The small store and gas station makes it easy to acquire forgotten necessities, ice and fuel. The restaurant attached to this facility is quite good - we've eaten breakfast and dinner there. There are many trails on the property which made for nice evening strolls. I return to Headwaters almost every year and have never been disappointed.

We stayed at Headwaters Cabins and it was nice and peaceful but expensive. We paid $350 a night for a small cabin. It’s only two miles from Yellowstone Park South Entrance is only open about 5 months from May to the end of September. This place has a gift shop, restaurant and a gas station. The restaurant was also pricey and the service is slow but the staff is nice and most of the workers are young kids who are there for the summer and live on site. If you want to stay near the park then stay at Headwaters Cabins.

Great family friendly lodge! We were there with our 10 and 12 year old kids. The pros: location is between Yellowstone and Grand Teton so it could be the sole home base for both parks; the rooms are up to date and have a fridge and microwave; the rocking chairs on the outside porch were wonderful to relax and chat; we really enjoyed the food at the restaurant; the kids were able to play outside and explore the area; there was a nice short hike down to Snake River; clean and comfortable. The cons: there's no air conditioning and there were big temperature differences between day and night so it was tricky getting to a comfortable temperature (we would open the windows during the day, it was warm when we went to sleep, then we had to close the windows sometimes after going to sleep because of being cold in the room); the area of the Lodge is expansive and this meant that it was a bit of a walk to get to the restaurant and store; it was farther to get to main attractions in Grand Teton than we thought, but still felt like a great location, just need to plan for some driving time between places. Overall, we all really enjoyed our stay there and would definitely go back! Rustic feel with lots of amenities.

The standard of rooms was what we expected after going through Glazier park. There just aren’t 4 star hotel in these areas so our expectations were not high. The cabins were fine, resturant ok ,but they have got to do something with the bartender Ed! He is not happy working there and was so awful to our group of 6 (ages 87-63) that we were stunned because no one in the hospitality industry has ever been so rude to us for no reason. He threw the menus at us, telling us we had to be seated by the resturant host next door and had to order food and drink and that he was closing at 9:30pm. When we asked if we could eat an ice cream bar he said that was “outside” food and when we asked about the parfait in the glass display he said that was “take-out food” and we could have none in his bar which was part of the lodge with no separating doors under the same roof. We just started laughing at his attitude and he came back to the table and told us, “it is end of the season and I can’t deal with you so do whatever you want.” All we wanted to do was watch the last 15 minutes of the NFL game. My 87 year old dad’s only request. It takes one thing to ruin a 3 night stay and his name was ED. Hopeful he has found another place to work that would make him a nicer person. (Only a family of 4 was in bar at 8:30pm and no one else came in so not busy.)

Outdated! WiFi ONLY in the lodge. Overpriced! I spent last night in Cooke City with nicer, more modern accommodations for 1/2 the price. I guess when your passing through, you have to pay to play. I would give it 1 star but the staff has been excellent.
