The Fiery Furnace is a small but concentrated maze of colorful sandstone fins and narrow slot canyons. This surreal geologic labyrinth earns its name from the deep red and orange glow of the sandstone fins that, when lit by the setting sun, resemble a 'fiery furnace'.

Visitors must obtain a permit or join a ranger-led tour to enter the Fiery Furnace
