The largest concentration of Ancestral Puebloan sites is at Chapin Mesa, where you'll see the densely clustered Far View Site and the large Spruce Tree House , the most accessible of sites, with a paved half-mile round-trip path.
If you want to see Cliff Palace or Balcony House , the only way is through an hour-long ranger-led tour booked in advance at the visitor center ($3). These tours are extremely popular; go early in the morning or a day in advance to book. Balcony House requires climbing a 32ft and 60ft ladder – those with medical problems should skip it.
