Families with children will enjoy the snow play area at Paradise, north of the upper parking lot — at least five feet of snow are needed before it can open. It is usually open by mid-December; in 2007, opening day was Dec 22nd. The Snow Play area is the ONLY place in the park where sledding and sliding are permitted. Trees, tree wells, and cliffs make other areas dangerous. For everyone’s safety, use soft sliding devices flexible sleds, inner tubes, and saucers. No hard toboggans or runner sleds. Due to construction in the upper parking lot the marked trail to the snowplay area from the visitor center should be used on weekdays.
