Located in Custer State Park, Legion Lake is quite a gem for only having a water surface of 9 acres and a 1/2 mile shoreline. It is absolutely astonishing to be able to glide through the still water and to be able to see the reflections of ponderosa pines and large rock walls. Campsites, fishing docks, cabins, a gift shop, and a restaurant lodge facilitate the area. A $15 Custer State Park entrance fee is required for each vehicle.
