"For anyone who believes that truly historic architecture doesn’t exist in the states, Mesa Verde National Park will make you think again. Still standing in the park are cliff dwellings built in 600 CE by the ancestral Pueblo people who once lived in the area. A transformative day trip, Mesa Verde is nearly two hours from Telluride but well worth the drive to see its 5,000 archeological sites, from Cliff Palace (a ranger will guide you on the hike up, which involves climbing ten-foot ladders) to Balcony House (which you’ll enter via a 12-foot tunnel)."
