Everyone working there was very kind and helpful and the cabins were incredibly clean. If you're visiting both parks, it's a GREAT location. The main lodge and cabins were still closed for the season when we visited, but Leeks Marina has a great pizza place just a few miles away and Jackson Lodge is a quick drive as well. There is a small store and gas pumps on site as well as laundry. Bathrooms were very nice for a campground.

We really really loved this campground. I imagine it could get a little tight in the summer as we stayed end of may and was not bad but did snow and the main roads in yellowstone closed a day or so but you can not beat the location between tetons and yellowstone.

Headwaters is beautiful. We drove to the Grand Tetons and saw so much wildlife. The campground is neat and clean. Highly recommend!

This campground is more or less centrally located between Yellowstone and GTNP-it's still a 3 hour drive to Mammoth Hot Springs and 2 hours to Jackson, but if you're planning to be in the area for a week or more, it's centrally located. The staff is friendly, the bathrooms are some of the cleanest campground bathrooms I've ever been in and the showers have HOT water-yay! My biggest complaint is the cost of electricity-$50/night :-( Does it Really cost that much for electricity in the area??? All in all, it is a great campground and the nearby gas station did not price gouge.

Nicely spaced sites. It was nice to have campfires. This campground was a great location for visiting the Grand Tetons as well as Yellowstone. The bathrooms were horrible! We arrived on a Wednesday and the bathrooms were dirty. On Saturday, I stopped in the office, which was closed at 8:45 a.m., so I left a note asking for the bathrooms to be cleaned. The men's bathroom was out of soap in all the dispensers. Women's bathroom had two toilet that were full of paper towels, the showers were dirty, hair in drains, floor had mud.... really disgusting. After writing to management, they were cleaned sub-par, in my opinion. I did not experience this problem when I stayed at Headwater a few years ago.

Great campsite in the Grand Tetons park. Also close to the Yellowstone entrance. Perfect place to stay when visiting both parks.
