The Black Hills really do come alive in the winter. Smowmobiling, skiiing, snowboarding, snowshoeing, cross-country skiing and ice fishing are popular here. In fact, some roads in Custer State Park are closed to cars and trucks for the winter, opening the roads to all kinds of outdooor sports. And because the deciduous trees have lost their leaves, wildlife is easier to spot in the winter.
Mount Rushmore is a year-round national monument, and the four faces can be quite striking with a layer of snow.
Although a lot of places in Keystone close for the winter, you will have no trouble finding a place to stay, eat or shop. So if you're hesitant to visit the Black Hills in winter, don't be. It's a most wonderful time of the year.
