Crater Rim Trail

The Crater Rim Trail circles the top of Capulin Volcano, a nearly perfect cinder cone that last erupted approximately 800 years ago and stands as one of the most accessible volcanic features in North America. The loop begins at the summit parking area, reached via a spectacular 2-mile road that spirals around the cone, and follows the rim through scattered scrub oak and pinon pine while delivering panoramic views across the volcanic field of northeastern New Mexico. On clear days the vista extends across four states: New Mexico, Colorado, Texas, and Oklahoma. The crater itself plunges 415 feet below the rim and measures roughly a quarter mile across, its interior walls streaked with dark basalt flows and orange oxidized cinders. The geological youth of the volcano is striking; the cinder deposits are so fresh that rainfall percolates directly through them rather than running off, creating the arid conditions visible on the slopes. Interpretive signs along the rim explain the formation of cinder cones, lava tubes, and the broader Raton-Clayton Volcanic Field surrounding the monument. Mule deer frequently graze the lower slopes, and golden eagles hunt the thermals rising from the sun-warmed cinders. The trail is short enough that most visitors combine it with the Crater Vent Trail in a single visit.
