The Fiery Furnace is truly unique amongst the sights in Arches National Park. It is a exotic labyrinth of sandstone fins, towering rock walls, and narrow passages that offer a challenging yet rewarding hiking experience for adventurous visitors.

The history of Fiery Furnace dates back millions of years to the Jurassic period when the sandstone formations were first deposited in the area. Over time, the natural forces of erosion sculpted the rocks into the intricate maze that we see today. The name “Fiery Furnace” is believed to have been inspired by the glowing red color of the rocks at sunset, which resembles the flames of a furnace.


The best time to visit Fiery Furnace for capturing photos is during the late evening. If you wait until sunset you will find that the land between the horizon and the furnace casts shadows on the entire area. As such you need to get to the viewing overlook approximately 90 minutes prior to sunset and then keep a close eye on the creeping shadow line. The prime color (the “fire”) will only occur for about 10 minutes so time is short to capture your photos.
