Zion National Park now pulls close to five million visitors a year — double its 2005 numbers — and it shows, especially on headline hikes like The Narrows, where wading through that famous river canyon means sharing the water with a constant stream of fellow travellers. But less than an hour west sits an alternative with the same red rock drama and a fraction of the foot traffic: Red Cliffs National Conservation Area.

Red Cliffs covers about 45,000 acres of sandstone cliffs, slot canyons and slickrock, laced with more than 100 miles of trails. It's run by the Bureau of Land Management rather than the National Park Service, which means no entrance-gate queues, no mandatory shuttle system and no rangers or visitor centres — just raw desert you explore on your own terms. Entry costs a modest $5 per car per day.

The signature hike is Red Reef, a three-mile out-and-back that starts innocently at a picnic area before threading into a narrowing slot canyon. Expect light scrambling, one fixed rope around a small waterfall, and a few chest-deep pools — you can turn back if the water gets too much, but push past that first waterfall and you'll likely have the canyon to yourself. It's widely considered an ideal first slot canyon for beginners.

Beyond Red Reef, the variety is impressive for such a compact area. A 7.5-mile slickrock loop passes 17 well-preserved Jurassic theropod tracks on the Dino Cliffs Trail. Snow Canyon State Park, inside the larger Red Cliffs Desert Reserve, offers petrified sand dunes and a one-mile Lava Flow Trail with three explorable lava tubes — bring a headlamp. A short hike from the Sand Cove trailhead reaches a small but pretty 10-foot arch above the Virgin River, and the Anasazi Valley (Tempi'po'op) Trail leads to Puebloan ruins. For a bigger outing, the Red Mountain Trail climbs into an 18,700-acre Wilderness to an overlook above Snow Canyon and the St. George valley.

Overnight options are simple but appealing: Red Cliffs Campground has 11 shaded sites within walking distance of Red Reef for $15 a night (bookable six months out), while the primitive Sand Cove group campground — free with a permit, 4WD access only — puts you right by the ruins trail. St. George is 15 minutes away for food and post-hike beers; Silver Reef Brewing Co. does pizzas, wings and solid lagers alongside its barrel-aged specials.

Wildlife adds another reason to slow down: keep an eye out for Gila monsters and the area's rare desert tortoises. Go between fall and spring for mild temperatures — summer desert heat here is no joke. For anyone who loves Zion's scenery but not its crowds, Red Cliffs delivers the slot canyons, scrambling and solitude in one easy-to-reach package.
