A maze of closely spaced sandstone fins form narrow canyons that can be fun to explore. It's easy to get lost! The name comes from the colors of the rock, especially intense at sunrise and sunset. The shaded recesses are actually a cool place to be in summer. Rangers lead tours inside. If you go on your own, you'll need to obtain a permit and learn about how to visit without damaging the soft sandstone. Try to sign up in advance for either the tour or a self-guided walk. Both tours and permits have a fee.
