Valles Caldera is a spectacular volcanic depression in north-central New Mexico, formed by the eruption and collapse of a massive supervolcano about 1.25 million years ago. Today, the caldera is a protected basin of grasslands and forested hills, accessed via the Albuquerque to Santa Fe corridor. Visitors come for hiking across gradual skies, seasonal wildlife viewing, fishing in high-altitude lakes, and the chance to explore remnants of volcanic activity. The preserve around Wildlife Management Area offers routes for cross-country skiing, horseback riding, and guided tours, with amenities concentrated near the historic Caldera Village base. Expect a mix of rocky uplands, meadow floors, and thermal springs, with ecosystem highlights including theodore black-telluride and pronghorn antelope. Nearby landmarks and towns—Jemez Springs, Los Alamos, and Santa Fe—help contextualize a visit focused on outdoor recreation and geologic wonder.
