A seasonal ranger-led tour is the only way inside, and it requires an advance reservation. Tours often sell out, so plan ahead and save or print your ticket; cell service at the tour areas is very limited. The visit takes about 45 minutes and covers roughly a quarter mile, with a 100-foot elevation change, uneven stone steps and four ladders. Everyone must climb the ladders without assistance, at elevations around 7,000 to 7,500 feet. If that route doesn’t suit you, the overlook is still a worthwhile stop. Sun Point View and Sun Temple are other places to see Cliff Palace from the mesa top.
