Take a gravel road to Lily Lake off the southern end of Beartooth Hwy. It's easily accessible by 2wd and RV, but if you'd like to go towards Crazy Lakes (few more large spots there) more clearance is nice to have (some rocks and ruts). Camping spots start well ahead of the lake, some by the edge of forest, some more open but with beautiful views on Abasoka range on one side and Beartooth on the other. Primitive camping only. Watch fire restrictions, if allowed then there are some rock rings created already. I was there in September 2020 and the colours of autumn (aspens) were stunning with the high mountains in the distance. Loved it. Frequent grizzly area so nat'l forests warnings about proper food storage.

Very nice quiet campground.Located by the shore of large lake. I thimk there were 12 or so sites available, each has table, fire ring and bear box. Some are literally by the lake, others further away surrounded by trees. To get to the campground you need to drive some miles on gravel road. Deep into the forest, so no traffic noise, just some wood cutting in the morning ;) There will be two other campgrounds on the way before you reach this one, Cherry Creek (similar to this one but smaller) and a RV and campsite s with marina (forget the name). Campground is owned by the Forest Service, so check on the website if campground is open after season - there may be no access to the campground (barrier) if officially closed. I was there in mid September and it was full.
