Ranger Programs

A ranger plays guitar to open an evening program in front of an audience at the outdoor amphitheater. The dunes are silhouetted under a sky with clouds and stars.
Images and videos are shown on a large screen during evening programs at Great Sand Dunes' outdoor amphitheater. Programs begin at dusk, and last about 30-40 minutes. They are usually followed by a laser-guided constellation tour when it's completely dark.
