When do Valles Caldera's summer hours end?
From Memorial Day weekend to Labor Day weekend each year, Valles Caldera National Preserve observes summer hours. During this time, the main entrance is open to vehicular traffic from 8:00 am to 6:00 pm daily. Beginning Tuesday, September 8, 2026, Valles Caldera will return to its regular hours of 9:00 am to 5:00 pm.
As a reminder, the park is open to pedestrian and bicycle/e-bike traffic from dawn to dusk every day of the year. For this purpose, there are pedestrian gates available at Sulphur Creek Trailhead, Redondo Creek Trailhead, Banco Bonito Trailhead, the main entrance, Rincon Trailhead, Rabbit Mountain Trailhead, and South Valle Grande Trailhead. We invite you to experience the absolute magic of Valles Caldera before or after hours. Once you've tried it, you may never want to visit from 9-5 ever again.
