D.O.C. has offered the widest variety of activities at Denali Park since 1995. Our mission is to enable greater access to more fun adventures for all skill levels at affordable prices. Choose from 2-hour, half-day and full-day whitewater and mild-water rafting trips, the more challenging inflatable kayak tour, a bike tour or bike rental, and kayak and canoe rentals on Otto Lake. We also have a campground and cabin rentals 10 minutes north of the park entrance. Group discounts & youth prices.
