Deer Mountain has it all when it comes to winter fun, skating, skiing, tubing and more. Deer Mountain is the only resort in South Dakota with a snow skate park. Deer Mountain Ski Area will maintain a ‘snow skate only’ park in its base area. The park is a series of boxes, rails, and tracks which riders slide across and balance on while executing tricks. Snow skates are skateboard-like decks with a hard plastic base that slides directly on the snow. The base has grooves, or channels, that help keep the snow skate going straight.
