This campground was our favorite so far on our 2 year journey. We were at site #27 that overlooked the lake. It was very secluded and all the camp sites were well spaced. It was a very busy weekend (Green River Rendevous) so we were only able to reserve 1 night. We were hoping to obtain a FCFS site the next day but there were none available. Went to the Museum of Mountain Men for one day of Rendevous & it was awesome.

Utile pour passer une nuit avant d’aller dans le parc. Comme il n’y a pas de service (Hors toilettes sèches), difficile de donner des étoiles. Faut environs 30-40 minutes pour arriver au lac

The restrooms were some of the cleanest I have ever experienced in a campground. Campground very clean. Great location, just 3 miles from the East entrance of Yellowstone.

3-mile site 19 was perfect, surrounded by wild roses and other plants and of course pines. We did fly fish the North Fork of the Shoshone with some success and visit Pahaska Tepee for an indoor lunch on a hot day. No 5G internet service while off the grid.
