The Alto trail is great, but strenuous, starting with a scramble up a cleft in the cliff. I love the view from the opposite trail near South Gap (also a strenuous climb). You look over Casa Rinconada at Pueblo Bonito and see them aligned with Alto on the horizon. Several other ruins are also visible east and west of Bonito. Beautiful.

While the area as a whole is an explorer’s delight, there is a hiking trail that embraces the entire culture of the park. The Pueblo Alto Trail has an overlook for Pueblo Bonito, the largest great house in the park. The trail also overlooks the other Chacoan buildings, takes you through Pueblo Alto and New Alto, brings you past famous Chacoan stairs built into the rocks and offers amazing panoramic views.

National Park Service Ranger Kayla Lanoue says the trail takes you through areas with the highest concentrations of cultural sites in the park.
