San Antonio Cabin often housed cowboys when the preserve was privately-owned and operating as a ranch.
About 1.2 million years ago, a spectacular volcanic eruption created a 14-mile-wide circular depression in the earth now known as Valles Caldera. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams. The area also preserves the homeland of ancestral native peoples and embraces a rich ranching history.
On Friday, July 25, 2025, Valles Caldera National Preserve turns 25. To celebrate this public land milestone, we invite everyone to three days of special programs and evening hours in their national preserve.
