Come to the top of the mountain for a unique summertime adventure on snow. Yes, at Keystone there is real snow in the summer on top of Dercum Mountain. Ride the enclosed gondola lift to over 11,000 feet and get ready for fast-paced fun, slipping and sliding and spinning down carved runs on big inner tubes. Adventure Point Tubing is a great way to get your heart pumping, and it is entertaining for the whole family. This is the world’s highest snow-tubing hill, and, in the winter, you can ride it during the day or under the lights at night. In any season, it’s an adventure of a lifetime for kids and adults alike. Tubing sessions last one hour, and tickets are available in the River Run Village. Advance reservations are highly recommended.
