This Ancestral Puebloan ruin is the most accessible of the archaeological sites, although the half-mile round-trip access track is still a moderately steep climb. Spruce Tree House was once home to 60 or 80 people and its construction began around AD 1210. Like other sites, the old walls and houses have been stabilized.

During winter, there are free ranger-led guided tours at 10am, 1pm and 3:30pm.
