Valles Caldera, also known as Jemez Caldera, is a 13.7-mile wide extinct volcanic caldera in the Jemez Mountains of northern New Mexico, near the town of Jemez Springs. The caldera was formed as the result of a spectacular volcanic eruption about 1.25 million years ago. The Valles Caldera National Preserve was established to protect this magnificent natural treasure. The area is full of scattered hot springs, streams, fumaroles, natural gases and volcanic domes. The highest point is Redondo Peak, a 11,253-foot high lava dome. The bottom of the caldera also has several grass valleys such as Valle Grande, the largest and the only one accessible by a paved road. Visitors can enjoy miles of ranch roads, livestock trails and game trails. There is a network of trails designated for horse riding.
