About This Route
The Narrows, Zion's premier slot canyon hike, involves wading upstream 9-16 miles round-trip through the Virgin River from Temple of Sinawava shuttle stop, with walls towering 1,000 feet and water depths varying from ankle to chest-high. This top-down adventure through hanging gardens and submerged boulders attracts thousands, but NPS records show flash floods cause most fatalities here.
Safety Considerations
Flash floods strike without warning, even from distant rain; check forecasts at Zion Visitor Center and heed 'Do Not Hike' signs. River flow over 150 cfs is hazardous per NPS gauges. Hypothermia risks in spring (water 40-50F); wear neoprene socks. Footwear must prevent slips on algae-covered rocks. Maintain 25-yard groups in narrows for voice contact. Wildlife like rattlesnakes inhabit dry sections; keep distance. Dehydration sneaks up in 90F+ heat; drink 1 gallon daily. Leave No Trace: urinate in river, bury solids 6 inches deep. Not for beginners; bottom-up from Chamberlain Ranch requires permit.
Essential Gear
Essential: NRS HydroSkin neoprene socks and Chaco Z/Cloud sandals or Five Ten water shoes for traction. Rent drysuit from Zion Outfitters if water exceeds 40F. Pack Gregory 3D Hydro 20L waterproof daypack, Katadyn Hiker Pro water filter, REI first aid kit, headlamp with extra batteries, and whistle. Include energy gels (GU Roctane) and electrolyte tabs (Nuun).
Emergency Tips
Flash flood: head to high ground immediately, avoid bends. Injury: stabilize in shallow water, signal upstream hikers. Hypothermia: remove wet layers, huddle for warmth, seek ranger evac via shuttle radio.
