The Narrows (Bottom-Up)

The Narrows is the slot-canyon section of the Virgin River in Zion National Park — a 16 km gorge where the river has cut 300 m deep into the Navajo Sandstone, narrowing to less than 10 m wide in places. There is no trail; the river itself is the route, and most of the hike is spent wading, occasionally swimming, upstream over slippery rounded cobbles. The bottom-up day hike from the Temple of Sinawava to Big Spring and back is the standard way to experience the canyon, and the only way without a permit.

The hike starts at the Temple of Sinawava shuttle stop at the end of Zion Canyon Scenic Drive. The first 1.6 km is the paved Riverside Walk; the river hike proper begins where the path ends and the canyon walls close in. Wading depth varies with season and water level — typically knee-deep with occasional waist-deep pools — and the going is slow on the river-rounded cobbles underfoot. The famous "Wall Street" section, where the canyon narrows to its tightest, comes at 5 km in; the legal turnaround for permit-free day hikers is Big Spring at 8 km, marked by a side-canyon waterfall on the right. The return is the same route. Most strong hikers complete the round trip in 6 to 8 hours; less experienced waders take 9 or 10.

The Narrows is unique because of the river. Outfitters in Springdale (Zion Outfitter, Zion Adventures) rent the essential gear: closed-toe canyoneering boots, neoprene socks, a wading stick — count on $30–50 per day, well worth it. Flash flood risk is real and the canyon can close on short notice when storms are forecast upstream; check with park rangers before starting. Best season is mid-summer (June–September), when water flow is lowest and temperatures highest; water temperature stays around 10–13 °C year-round. In spring (April–June) the snowmelt-swollen river closes the canyon entirely. The Top-Down Narrows (a 26 km point-to-point starting at Chamberlain's Ranch) requires a separate permit.
