The Colorado National Monument is open 24 hours a day. There isn’t an official trail curfew, but you still need a valid park pass even at night. While the National Park Service permits nighttime hiking, it encourages visitors to explore between dawn and dusk because trail navigation and emergency response become much more difficult after sunset.

Why Daylight Is Safer—And Why Night Hiking Is Worth It

The good news? You can legally hike the Monument's trails after dark, but there are a few important safety considerations that every visitor should know. Many monument trails cross uneven slickrock, loose gravel, steep drop-offs, and remote canyons where route finding becomes far more challenging in the dark. Cell service can also be unreliable in parts of the park, making preparation essential.

Still, experienced hikers are rewarded with cooler evening temperatures, outstanding stargazing thanks to low light pollution, and the chance to hear or spot wildlife that's most active after sunset.

If you don’t have a quality head lamp with extra batteries, don’t hike the monument at night. Relying on your phone to light the way won’t cut it. Make sure you have offline trail maps before you enter the park, and you’ll need just as much water at night as you would during the day. You might be an extra layer. You can always leave it in the car if it’s still too warm when you head out.
