Canyoneering is an activity that involves hiking as well as rappelling, downclimbing, route finding, rope work, and swimming in cold water to allow you to see much more remote and secluded scenery than you could by simply hiking. Zion National Park is considered a mecca for canyoneering with several world-famous canyons like the Zion Narrows and the Subway, as well as countless obscure and remote canyons. These routes are not suitable for hikers who have no technical canyoneering experience.
A canyoneering permit is required for any canyoneering route that requires the use of descending gear or ropes. Reservations for the well-known canyons can be made online and you must pick up your actual permit at the Wilderness Desk the day before or the day of your hike. A lottery system is in place for Subway and Mystery Canyon permits due to their epic popularity. Detailed permit info can be found on the NPS website.
You need a climbing harness and a rappel device (ATC-type device or better yet, a canyoneering-specific device like the Petzl Pirana or Imlay Canyon Gear Critr3) and you must know how to use them for rappelling.
You need canyoneering rope long enough for the longest rappel. Static canyoneering rope is prefered to dynamic climbing rope. (Note: general-purpose rope that you find at the hardware store is absolutely NOT acceptable.) You typically bring double the length of the longest rappel since you pull and take your rope with you.
Inspect all anchors before you rappel off of them. While rappel stations in the popular canyons are usually in good shape, they are not officially maintained by NPS staff. Bolts and webbing are replaced by white knights in the canyoneering community. You should bring webbing and a few rapid links and be knowledgeable to clean up any anchor that looks like it's in bad shape. Your safety is your responsibility.
Be prepared to get wet and cold. Most canyons have sections of water, often in dark corridors that don't get much direct sunlight. Bring drybags to protect all of your camera gear, electronics, and anything else that needs to stay dry. Canyons like Keyhole Canyon and Pine Creek have perpetually cold swims, so you will want a wetsuit even on a hot day in summer.
Be prepared to deal with random obstacles. Many canyons have short drops that require careful downclimbing, chimneying, and/or stemming. Good upper-body strength and some climbing experience are very useful. Random logs and debris will need to be evaluated and navigated.
Flash floods are a real danger and have killed several people over the years. Pay attention to the weather forecast and cancel your canyon plans if there is a threat of rain. Your safety is your responsibility.
You cannot hire a guide to take you through the technical canyons of Zion National Park; commercial guiding is prohibited. Outfitters in the area do offer canyoneering training classes and they also lead canyoneering adventures in public lands outside of NPS. Most outfitters also rent canyoneering gear (harnesses, wetsuits, footwear, drybags, etc.), but typically not rope.
Do not poach any canyon that you do not have a permit for. Rangers can and do ask to see your canyoneering permit, especially in popular canyons like the Subway.
Strenuous semi-technical canyoneering.
The Subway "top-down" route is a classic canyoneering hike through the Left Fork of North Creek, involving several short rappels, a few downclimbs, and several cold swims. The highlight of the day is the half-mile section of canyon known as The Subway with its famuous tubular sandstone formations. This strenuous hike is well worth the effort!
Strenuous semi-technical canyoneering.
Orderville Canyon is the amazing little sister to the famous Zion Narrows and is a great semi-technical canyoneering adventure for beginning canyoneers and experienced hikers. Aside from being a long and strenuous hike through a wet canyon, there are many obstacles to downclimb, two short rappels, and multiple swims. The canyon ends in the Zion Narrows.
Short technical canyoneering.
Keyhole Canyon barely shows up on a topo map, but it is a beautiful little subterranean slot that offers up some amazing other-worldly slot canyon scenery. This route takes roughly two hours to complete and involves 2-3 short rappels, and as such, it is quite a popular route for beginning canyoneers. Full technical gear is required and wetsuits are recommended.
Fairly strenous technical canyoneering route.
Pine Creek is one of the most popular technical canyoneering routes in Zion National Park and exemplifies the beauty of subterranean slot canyons. With several stunning rappels, the magical arch formations the Cathedral, many downclimbs and cold swims in dark corridors, and the intimidating 100-ft free rappel into the grotto, Pine Creek is a classic.
Fairly strenuous technical canyoneering.
Mystery Canyon is a deep and beautiful hanging canyon and is one of the most coveted canyoneering adventures in Zion National Park, featuring a steep and intimidating entrance, numerous rappels in dark sculpted narrows, and two big-wall rappels near the end that really get your attention. The grand finale is the rappel down Mystery Falls into the Zion Narrows.
Fairly strenuous technical canyoneering.
Echo Canyon is the large canyon complex located above Weeping Rock. Most hikers catch only a few glimpses of the slot canyon sections as they hike the Observation Point Trail/East Rim Trail, but the middle section of Echo Canyon is a great technical canyon involving several short rappels, downclimbs, and swims through cold water in subterranean scenery.
Strenuous canyoneering route.
Spry Canyon is a large drainage that starts in the Upper East Canyon under Deertrap Mountain and makes its way down to Lower Pine Creek. A descent of Spry Canyon is a fun canyoneering adventure through beautiful and rugged scenery, but several awkward rappels and difficult downclimbs make this a more serious affair than some of the other popular Zion canyoneering routes.
Strenuous technical canyoneering.
Behunin Canyon is a majestic hanging canyon that cuts through the White Cliff formations down into the Emerald Pools pantheon. Hikers along the West Rim Trail can get a glimpse down into the impressive canyon. A descent of Behunin Canyon involves several big-wall rappels that make this a more serious and intimidating affair than some of the more popular canyoneering routes.
Strenuous technical canyoneering route.
Misery Canyon is a technical canyon that skirts the eastern border of Zion National Park and the approach hike starts from Checkerboard Mesa Canyon within the NPS boundary. While Misery isn't too technically difficult, it is a physically demanding slot canyon that ends in the beautiful Barracks section of the East Fork and requires a long and brutal uphill exit hike.
