Warm lake, not crowded
Went here deliberately because it is not extremely busy and has a warm lake for swimming, boating, tubing. Canoing that is very near the campground. Fantastic restaurant in Genora, ND about 5 miles away. Went in late July and flies were somewhat bothersome. But lake was so refreshing and this would make a perfect 1-2 day stop between many locations in MT and ND. 27 miles to Canadian Border. Went swimming every day I was there except one day when it was cool. 150 miles to Theodore Roosevelt National Park which was also great.
