I had the best experience at this site! It is right in between Grand Teton NP and Yellowstone NP. This is definitely the place to stay at if you plan on visiting one of the two or even both Parks! The campground is beautiful and extremely well maintained with many different campsite options to suit the needs of your stay. The bathrooms are very clean and the showers are super hot. The staff is absolutely wonderful! They were friendly, knowledgeable, and helpful which made me feel right at home. If I am ever back in the area this will without a doubt be the place I stay at!

We stayed in this campground in early May 2024 for four nights. There was still snow on the ground and one of the camp hosts dug out our fire pit and picnic table for us (thank you!). Lots of pine trees, birds, and pica (ground squirrels). This campground is only two miles from the South Yellowstone National Park entrance, so it is convenient for seeing the lower loop sites in Yellowstone. Hosts are very nice and helpful.

We loved this spot, located between Yellowstone and Grand Teton, it was perfect. We loved the cabin which was well-insulated and stayed much warmer than the freezing temperature outside at night. The bathrooms were well-lit, conveniently located, and had warm showers and a dishwashing station. Overall the campground felt welcoming and taken care of and we would love to stay again!

Large campground south of Yellowstone and north of Grand Teton. We used this campground to access the southern loop of Yellowstone since we could not get a site in Yellowstone. Sites were good size, spacing was fair, and mostly level. Full hookups, but the sewer hookups are very high, almost a foot off the ground. They have a side port that’s not quite as high, but the threads on mine were messed up. Got staff to help, and they got them fixed, but still high and had to “slinky” it out when dumping. Forest around the campground was burnt a few years ago, so it’s not appealing driving in. Finding the campground was a little difficult as there was very minimal signage driving in the complex. It’s across from the gas station. Gas prices here was darn near the cheapest the entire trip. We made sure to fill up! Staff checking in was helpful. Staff helping with the sewer issue was moody. The lodge next to the campground was really nice and they have great Wi-Fi open to the public 24/7. No t-mobile cell coverage. Would not say it was worth the $100 per night fee, but when it’s the only option, they can charge what they want.

Great check-in Host, Mary. Very kind and welcoming! Wish it wasn’t the last day for the park as we would have stayed longer.

Stayed for 3 days, location was good as it is between Teton and Yellowstone. Place is clean and personnel are helpful and friendly, though some of the RVs are using generators overnight and its quite loud. But overall experience was good!

This campground was in a very central location to see most sights in Yellowstone National Park and the Grand Tetons National Park. The facilities were very clean and modern, plenty of trees and the sites were separated nicely from other sites. The staff was very friendly and knowledgeable. We would definitely camp here again if in the area.
