Red Reef Trail follows Quail Creek up a narrowing slickrock corridor at Red Cliffs Recreation Area, with the trail dipping in and out of the creek itself depending on where the easiest line is. You park at the same trailhead as Owens Loop, walk past the campground, and head upstream into the canyon. The payoff is a series of pothole pools at the head of the trail — a slickrock pour-over, a deep plunge pool, and the option to keep going (with rope assistance) into the upper canyon.
What "wading required" actually means
The trail crosses Quail Creek several times, and the first major crossing is about a third of a mile in. Whether you get wet depends on the season. In March or April after a wet winter, the creek runs strongly and at least one crossing will be calf-deep. In October it's usually rock-hops. In summer it's often dry on the surface. The "wading" framing is most accurate in spring, when families show up in sneakers and end up walking the rest of the trail with squelching feet.
The pools at the top
The trail's destination is a sequence of three pothole pools cut into the Navajo sandstone where the creek pours over a series of ledges. The lowest pool is wadeable in low water and swimmable in spring. The middle pool requires either climbing the slickrock pour-over or taking a steep bypass on the right. The upper pool requires actual scrambling and is where most family parties turn around. Beyond the upper pool, the trail continues into the Red Reef proper, which involves either rope work or a long bypass.
The slickrock corridor
What makes Red Reef worth the walk is the canyon itself — narrow Navajo sandstone walls, the creek doing its work across slickrock benches, a few cottonwoods clinging to the corners where the soil holds. The cliffs are tall enough that the canyon stays in shade for most of the morning, which makes it one of the few Washington County trails where summer mornings are genuinely comfortable. The shade ends at the upper pools where the canyon opens up; if you continue past that point, expect full sun.
The hard rules
You're inside the Red Cliffs National Conservation Area, which is desert tortoise habitat. Dogs must be leashed. Don't go off-trail except to step around a wet section. Don't collect anything. The BLM enforces these rules — rangers patrol the campground and trail in spring break weeks. The creek itself is also tortoise water in dry years; don't muddy the lower pools unnecessarily.
Spring is the season
Most St. George hikers have a specific Red Reef rotation: hit it in late March or early April when the creek is full, the pools are deep enough to swim, and the canyon is alive with wildflowers along the upper benches. A second window in October catches the fall color in the cottonwoods. Summer is too hot, deep winter sometimes ices over the upper pools.
Where it fits
Red Reef and Owens Loop are the two trails most St. George families do at Red Cliffs Recreation Area, often combined into a single morning — Owens for the slickrock warm-up, Red Reef for the creek and the pools. The trailhead is twenty minutes from downtown St. George and the parking lot fills up early on spring weekends. Cottonwood Forks branches off further upstream for parties wanting a longer day.
