This Arizona Waterfall Only Appears a Few Days a Year

For most of the year, there’s nothing to see at Sycamore Falls. No trickle. No mist. Not so much as a hint that the tucked-away canyon in northern Arizona hides one of the most striking waterfalls in the Southwest. Then, after a storm or during peak snowmelt, the landscape changes overnight. Water suddenly pours over the basalt cliffs, plunging into the glassy, almost perfectly circular pool below. Days, sometimes a day, later, the cascade disappears just as quickly.

Hidden within Kaibab National Forest between Flagstaff and tiny Williams, Sycamore Falls is one of Arizona’s most fleeting natural wonders. Its elusive nature, combined with proximity to marquee destinations like the Grand Canyon, less than two hours away, explains why it’s so often and easily overlooked—and why catching it at peak flow feels like a not-so-small victory.

When timing aligns, typically during spring snowmelt or shortly after heavy rain in the summer monsoon season, the payoff is spectacular. The main waterfall tumbles 70 feet over a wide ledge, the streaked rock columns providing dramatic contrast against the fast-moving water. Nearby, two smaller seasonal falls also come to life, creating an impressive, unexpected cluster of cascades in an otherwise quiet slice of forest. In winter and early spring, conditions can be even more striking: During weather extremes, the falls may freeze, forming thick icicles and sculptural ice against the cliff face.

Despite how remote this area feels, Sycamore Falls is relatively easy to reach. From Phoenix, it’s less than a three-hour drive; from Flagstaff, under an hour; and from Williams, closer to 30 minutes. Once you get off I-40, the final stretch follows a rough, washboard forest road. In optimal conditions, most vehicles can make it, but high clearance is strongly recommended—especially in winter and after storms, when washouts, flooding, or snow accumulation are possible.

The unpredictability is part of the experience. During one attempt in January (I’ve been to Sycamore Falls four times), we got within a couple miles of the trailhead before hitting an impassable wall of snow and having to turn around. While the U.S. Forest Service maintains the road, winter upkeep is more limited, and conditions can change quickly. On a February trip timed right after a storm, we arrived one day early and found a dry waterfall. Checking recent reports on AllTrails is one of the best ways to gauge whether the falls are flowing and current road access.

Once you arrive, the hike to Sycamore Falls is fairly short, but it demands attention. The trail traces the canyon rim, and there are no guardrails. While the falls sit within a national forest, no permits are required and parking is free.

Pair your adventure with a visit to Williams, home to the historic Grand Canyon Railway and drive-thru wildlife park Bearizona. Or, base yourself in Flagstaff, a college town known for its robust craft beer scene, easy access to Arizona’s high country, and the Lowell Observatory (where Pluto was discovered). If you really want to immerse in nature, Backland Luxury Nature Resort offers luxury glamping tented suites 10 minutes from Sycamore Falls.
