The Balcony House Tour in Mesa Verde National Park is a one-hour, ranger-guided experience that provides a chance to learn about a mid-sized cliff dwelling with 38 rooms and two kivas. This strenuous tour requires participants to descend a 130-step staircase, climb a 32-foot ladder to enter the site, navigate small ladders and uneven steps in the dwelling, crawl through an 18-inch wide by 12-foot long tunnel, and ascend a 60-foot open cliff face with uneven steps and then back down two 17-foot ladders. Reservations are required and can be made through Recreation.gov or by calling 1-877-444-6777, starting 14 days in advance. The tour begins at the Balcony House parking area on Cliff Palace Loop Road, which is accessible seasonally. It is not recommended for individuals with heart or respiratory issues, problems with heights and ladders, and children must be able to climb the ladders on their own.
