Beautiful lake - looks like the Caribbean in Montana! Somewhat close to West Yellowstone for those visiting national parks. Odd campsites required reservations (even if you show up and there’s one open for the night, the sign says you still have to go to recreation.gov and reserve it) and Even sites are first come first serve. Small campground and relatively small parking lot but we went on Monday July 5th and it wasn’t busy! Excellent spot to kayak or use a small boat but it’s all BYO, no rentals anywhere nearby that we saw. Mostly families enjoying a laid back lake day. Picnic tables first come first serve for day use.
