Thing to Do
Hike the Cerro Abrigo Loop
NPS/Raelyn Toya
This 7.2-mile (11.6 km) loop gently ascends a lava dome and then contours around it, offering unparalleled views of much of the eastern half of the caldera. The loop may be hiked in either direction, although counterclockwise is strongly recommended. Excellent opportunities abound for elk and other wildlife sightings.
