Quick Info
What: Ancient Puebloan ruins and dramatic twin rock spires. Access: Guided tours only (May-September). Location: 20 miles west of Pagosa Springs. Duration: 2-3 hours for tour. Significance: Astronomical observatory site, Chaco outlier.
Chimney Rock National Monument protects one of the most dramatic archaeological sites in the Southwest. Twin rock spires rise 300 feet above a high mesa where Ancestral Puebloans built structures aligned with celestial events over 1,000 years ago. The site connects to the famous Chaco Canyon civilization and may have served as a distant outpost and astronomical observatory.
Unlike self-guided ruins, Chimney Rock requires joining a guided tour—a format that enhances understanding of what you're seeing. The tours interpret not just the structures but the landscape, astronomy, and culture that gave the site meaning.
Tour Options
Walking Tour
The standard experience. Guides lead groups along the mesa, explaining archaeological features, cultural significance, and astronomical alignments. Moderate walking on uneven terrain. Most visitors take this option.
Sunrise/Full Moon Tours
Special programs at significant astronomical times. Experience the site as the ancient inhabitants would have during celestial events. Limited availability—book well ahead.
Kiva Tour
Deeper exploration including interior access to reconstructed kiva. More intensive archaeological focus. Check schedule for availability.
The Archaeological Site
Great House: Multi-room structure on the high mesa, built in Chacoan style around 1076 CE. The architecture required significant labor and organization.
Twin Pinnacles: The dramatic rock spires define the site. Every 18.6 years, the moon rises between them—an event the ancient inhabitants clearly marked. This lunar standstill cycle may explain the site's location.
Lower Sites: Pit houses and smaller structures on the lower mesa show longer occupation and different building styles.
Chaco Connection: Architecture and artifacts link Chimney Rock to the Chaco civilization 90 miles south. The site may have been a pilgrimage destination or astronomical outpost.

Tips
Book tours in advance. Popular times and special programs fill up. Don't assume walk-up availability.
Bring water and sun protection. The mesa is exposed with no shade. Summer can be hot.
Wear sturdy shoes. The trail involves uneven surfaces and some climbing.
Arrive early. Check-in at the visitor center before tour departure. Late arrivals may miss their tour.
Consider special tours. Sunrise and full moon experiences add dimension that daytime visits can't match.
Frequently Asked Questions

Chimney Rock is smaller and less famous but offers more intimate tours and dramatic setting. Mesa Verde has cliff dwellings; Chimney Rock has the twin spires and astronomical significance.
Is it worth visiting?
Yes, especially if interested in archaeology or astronomy. The site's beauty and the guided interpretation make it memorable.
Good for kids?
Older children with interest in history will enjoy it. Younger kids may find the walking and talking challenging. Tour guides engage different ages.
What about the lunar standstill?
The major lunar standstill occurs every 18.6 years when the moon rises between the twin pinnacles. Special viewing events accompany this rare occurrence.
