Capulin Volcano National Monument in northeastern New Mexico is one of the few places in the world where people can walk into a volcano.
A road spirals up the inactive volcano to the summit, where two self-guiding trails begin. One trail leads to a vent at the bottom of the crater; the other, longer trail follows the crater rim. From the highest point on the rim trail, more than 8,000 feet above sea level, one can see three states, as well as stunning views of the Sangre de Cristo Mountains to the west and the Cimarron Cut-Off of the Santa Fe Trail to the southeast.

Capulin Volcano, in New Mexico, allows visitors to hike inside a volcano.
During the late 1800s, wagon trains heading for Fort Union passed by the volcano. About ten miles from Capulin Volcano is the Folsom Man site, where human remains and projectile points were first found in association with extinct animals.
Capulin Volcano is part of a field of volcanism that began about eight million years ago. Recent studies indicate that Capulin Volcano is approximately 59,000 years old.
During its last eruption, cinders, ash, and other rock debris spewed out and fell back upon the vent, piling up to form a cone-shaped mound rising more than 1,000 feet high -- one of the largest and most symmetrically shaped cinder cones in the United States.
