The Narrows from the Bottom Up

The Narrows from the Bottom Up is a strenuous 9.4-mile out-and-back from Temple of Sinawava to Big Spring and back. The first mile follows the mostly flat, paved Riverside Walk; at its end, stairs drop into the Virgin River, where the riverbed becomes the trail. The draw is the slot canyon itself: tall sandstone walls close in around the water as you walk upstream, and the experience keeps changing instead of building to one overlook. Choose this if you want hours of wading through a canyon, not a dry walk with a quick viewpoint.

Big Spring is the maximum bottom-up day-hike limit. It is 4.7 miles each way and 9.4 miles round trip; the saved route maps the outbound line once because you retrace it. The park lists 334 feet of elevation gain and a broad one-to-eight-hour estimate that includes shorter turnarounds; plan on roughly seven hours if you go all the way. Orderville Canyon joins about two miles upstream and is a common turnaround. You can explore only the first quarter-mile of that tributary; that side trip adds distance. For a shorter outing, walk Riverside Walk to the river-entry steps and return on the pavement.

During shuttle season, take the free Zion Canyon shuttle to the last stop, Temple of Sinawava (Stop 9), then follow Riverside Walk to the water-entry steps. Zion Canyon Scenic Drive is shuttle-only for most of the year; in the off-season, check whether it is open to private vehicles before planning to drive up. The trailhead area has restrooms and a water-filling station, but there are no bathrooms along the hike. Bring food for the full day. The bottom-up day hike to Big Spring does not require a wilderness permit; the separate, roughly 16-mile top-down trip does. Pets are not allowed.

Once you leave pavement, movement is slow: the bed is made of slippery, unstable boulders, while current and depth change from day to day. NPS says at least 60% of the hike is spent wading, with some stretches deep enough to require swimming. The 334-foot climb sounds modest, but the river and footwork make this much harder than the elevation number suggests. A walking stick and closed-toe footwear help with balance; colder seasons may make river gear useful. The river itself is the route, so do not expect a continuous dry path.

Upstream from Temple of Sinawava, the Virgin River cuts through Navajo Sandstone, forming the slot. At Temple, the river reaches softer Kayenta Formation, which erodes faster and helps widen the canyon at its mouth. That geology explains why the walk shifts from open Zion Canyon to a tight river corridor. Orderville's junction and the changing walls, seeps, springs, and rock shapes give you new things to notice along the way; there is no single best viewpoint. From inside the river, the water below the walls is the simplest way to show their scale in a photo.

Water level, temperature, and speed vary. Check the current flow and park alerts before entering: the Narrows closes when the Virgin River is above 150 cubic feet per second or during a National Weather Service Flash Flood Warning. Flash floods can happen even if the trailhead is dry. Do not drink the river water or submerge your head because of toxic cyanobacteria.
