Valles Caldera National Preserve

Jemez Springs, New MexicoBortle 2 Best in Summer

Truly dark sky, with the zodiacal light clearly visible.

Valles Caldera is a massive volcanic crater, eleven miles across, in the Jemez Mountains of north-central New Mexico. The preserve is certified by DarkSky International and the bowl of the caldera creates a natural amphitheater that reduces horizon light even further. At 8,500 feet elevation, the air is thin and transparent. Elk herds graze the meadow floor, and on clear nights the Milky Way reflects in the small ponds scattered across the valley.
