Slot Canyon Atlas

AtlasSan Rafael Swell - Eastern Reef

Little Wild Horse Canyon

verified ACA 2A Extreme flood risk Goblin Valley / Hanksville, UT

The Swell's marquee non-technical slot: tight, sculpted sandstone narrows that you can walk through without rope, usually run as a loop with Bell Canyon.

Bell Canyon is the partner route and shares the same trailhead; the standard loop is about 8 mi total. The slot's accessibility is also its risk profile: the 2020 fatalities happened to an experienced group on a forecast that read clearer than the storm cell that actually hit. Watch the entire Eastern Reef forecast, not just the trailhead.
