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.

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

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.

This is a hard sided camping vehicle site only, so not for tents, which we somehow had not realized. The hosts were very nice and helped us find another option
