It's easy to overlook this three-track flume ride hidden on the far red slope of Mt. Gushmore. Yet if you have the courage to carry your tube all the way up to the top, you'll eventually come upon three twisting, turning flumes—even one that's in the dark (keep in mind the tunnel slide is for single riders only, while the open slides are for one- or two-passenger tubes). Once you're in, it's way more fun than scary. Still, guests who are pregnant or who have heart, neck,
or back problems should skip it. For people with disabilities: Guests using wheelchairs must transfer to inner tubes. It's worth riding both an open slide and the tunnel slide, but remember that the tunnel slide is only for single riders.
