The President’s Slide and Rushmore Tramway (203 Cemetery Rd., 605/666-4478, www.rushmorealpineslide.com , Memorial Day–Labor Day daily, closed in off-season, adult $8–10, child $3) is a short but enjoyable ride. The lift is located right in Keystone  and climbs the ridge of a nearby mountain.
The chairlift ride to the top of the mountain is a relaxing and quiet ride. On the way up, watch the faces of the folks enjoying the alpine slide down the hill. The alpine slide looks much like a sled on very small wheels.
There are two tracks to choose from on the trip down. One is for the slowpokes, many of whom look terrified as they ride their brakes down the hill; the other is for the racers who zoom down the hill with a look of sheer manic bliss on their faces.
This is a ride for all ages, but not necessarily for the timid at heart. At the top, there are several boardwalk viewing decks from which there are distant views of Mount Rushmore , and lofty views of the town of Keystone just below. The rock and flower gardens at the top are beautifully done and a casual grill serves brats, burgers, and chicken sandwiches priced around $4.50–6.
Beer is available also, though it would likely not be a good idea to imbibe heavily and then alpine slide down the hill. After enjoying the gardens and the views, slide or ride the chairlift down; the choice is yours.
