Great small corps park to camp during cool weather. It is a very beautiful area to camp in with lots of hiking areas. Map Quest it before looking for it and it will save you anxiety and time. We camped here in a Travel Trailer.
Cold Brook Lake Corps of Engineers, just north of Hot Springs, SD. No reservations, $5 fee. No hookups. A few small shade trees. Pit toilets. Located near small reservoir with swimming beach. Many open sites mid week in June. Thirteen well separated sites, fairly level. Some deer flies. We would go there again. Evans Plunge, historic indoor and outdoor pools, is located in Hot Springs. We camped here in a Fifth Wheel.
