Black Hole of White Canyon

Best for: Swimmers
Distance: 5 miles
The Black Hole is the flume of our thrill-ride hikes—a slot canyon that must be swum. It’s deep and dark and filled with cold water year-round, requiring a wetsuit even when temperatures are broiling far above. After a short hike, you plunge into the muddy stream and swim down (many spots are wadeable depending on the season) for two miles, peering up at the sheer sandstone walls towering hundreds of feet above. You can also check out the markers of the raw power of the Colorado Plateau’s flash floods in the canyon: Look up and you will see dead trees wedged in the slot as far as 50 feet above you, where torrential water once carried them. At times that debris has blocked the canyon, sometimes requiring ropes and a lot of forethought to navigate precariously piled logjams.
Those floods are an ever present danger in this peaceful spot—in the 1990s a teenage girl was swept to her death down here. But keep an eye on the weather, and you can simply bob downstream, relax, and enjoy the craftsmanship of the rushing water that carved out this enchanted canyon. Some canyoneers even bring a little inflatable ducky children’s pool toy along to use as a kickboard heading downstream.
Thrill Factor: You must be able and willing to swim and wear a wetsuit even in the summer (a short-sleeve one will work when it’s full summer). There are no real technical obstacles to navigate in the canyon, but it’s not a bad idea to have at least a small rope in case you don’t feel comfortable downclimbing. Also, floods can change things—in 2003, they created new technical obstacles that have since shifted away. Once you are in, you are fully committed—there’s no escape route—so analyze weather reports before you attempt it and be aware that storms far upstream cause flash floods.
Take It Easy: If you want your first taste of Utah slot canyons, try the nine-mile loop up and down Little Wild Horse and Bell Canyons in the San Rafael Swell, not too far from White Canyon. They offer up the real slot experience with no technical obstacles or swims.
