Fodor's Expert Review Fiery Furnace Walk

Join a park ranger on a 2½-hour scramble through a labyrinth of rock fins and narrow sandstone canyons. You'll see arches and other eye-popping formations that can't be viewed from the road. You should be very fit and not afraid of heights or confined spaces for this moderately strenuous experience. Wear sturdy hiking shoes, sunscreen, and a hat, and bring at least a liter of water. Guided walks into The Fiery Furnace are offered mid-April through September, usually a few times a day (hours vary), and leave from the Fiery Furnace Viewpoint, about 15 miles from the park visitor center. Tickets must be reserved ahead ( www.recreation.gov) and are available beginning six months in advance and up to four days before the day of the tour. Children under five are not allowed. Book early as the program usually fills months prior to each walk.
