The Narrows, Zion National Park
A five-card field guide to Zion's The Narrows, covering the river route, permit boundaries, flash-flood checks, and water-safety cautions before you step into the canyon.

A river walk through Zion's tightest canyon is unforgettable, but it is not a casual sidewalk hike. Use this five-card field guide to decide whether conditions, permits, route limits, and river hazards fit your day.

Card 1 — Why it matters. The Narrows is the narrowest section of Zion Canyon: the Virgin River becomes the route, sandstone walls rise about 1,000 feet above hikers, and in places the canyon is only about 20 to 30 feet wide. 1
Card 2 — The usual route. Most first-time visitors choose the bottom-up hike from the Temple of Sinawava; this option does not require a wilderness permit, and the legal upstream turnaround is Big Spring, making the full version about 9.4 miles out and back. 2
Card 3 — Know the line. The 16-mile top-down route requires a Zion wilderness permit, while bottom-up hikers may not continue above Big Spring or travel more than one-quarter mile into Orderville Canyon. 3 4
Card 4 — Floods decide the day. The park notes that at least 60% of the hike involves wading, walking, or sometimes swimming in the river, and flash floods can raise water levels within minutes or even seconds; if threatening weather is present, do not enter the narrow canyon. 5 Before leaving, check the official conditions page, the National Weather Service flash-flood potential, and USGS Virgin River flow; Zion closes The Narrows when flow is above 150 CFS or when a Flash Flood Warning is issued. 6
Card 5 — Treat the river as unsafe to drink. Zion warns visitors not to drink from park streams, not to submerge their head in the Virgin River, and to avoid contact with benthic cyanobacteria, which can attach to rocks, plants, and river edges and may produce toxins; children and pets need extra caution around affected water. 7
Quick planning notes
- Start early, move slower than your normal trail pace, and turn around before fatigue turns the river crossing into a problem.
- Check the official conditions page close to departure rather than relying on memory from a past trip. 6
- Do not treat a clear sky at the trailhead as enough information; storms upstream can still affect a slot canyon. 5
- The final card uses an official Zion water-safety context image; it is not a pet-access endorsement for The Narrows.
