The Fiery Furnace; my favorite part of Arches National Park. Entry permits are required. To acquire a permit you pay a small fee and watch a short video while you learn how not to disturb the fragile environment in the Fiery Furnace. Ranger-guided tours are available and recommended for those who have not been here before. It's easy to get lost. Click here to view a 360° QuickTime panorama from this spot.
