Rising to over 8,700 feet, northeastern New Mexico’s Sierra Grande Peak is a geologically unique landscape borne of a violent past. Sierra Grande is an extinct shield volcano and offers opportunities for hiking, mountain biking, wildlife viewing, photography and studying geology. If you are looking for a new area of New Mexico to explore, if you enjoy vast open expanses, and if you enjoy a long hike with a steady modest incline, then Sierra Grande is the adventure for you.
