This park is in a beautiful, remote area. Be sure to pack everything you need, because there is no store nearby. The cabin was nice and had a good air conditioner. Bathrooms were well kept and cleaned regularly!
Beware of the swimming area, though: Our group all got multiple cuts on their feet and some had pieces of shell imbedded in feet while swimming. Water shoes are a must!! Being South Dakota, it was also crazy windy for part of our stay. Also, the drinking water tasted bad and did not agree with my stomach. I would bring plenty of drinking water, and a night light if you're using the cabins.
