Most sledding in Estes Park accompanies private or commercial lodging, meaning if you stay, you can play. Private rental houses might have a small hill in their yard or a lodge might sit on acres of undulating terrain perfectly suited to tubing. Although there's not a designated sledding area in Estes Park, there is one inside Rocky Mountain National Park at Hidden Valley. It makes for a great afternoon activity for families or those who are young at heart. Bring your own sled or tube, or rent one from a local outdoor gear or sporting goods store.
