Canyoneering is the act of travelling through a canyon.
What it is
Canyoneering usually involves descending a canyon, and often requires a variety of techniques and skills, including hiking, scrambling, climbing, rappelling, jumping, and/or swimming.
A typical canyoneering trip may consist of:
- The approach: hiking up or along a fairly well-established trail then branching off the main trail to descend into a drainage via a smaller, more difficult trail (the drop in). These trails are often very steep.
- The descent: hiking downstream in a drainage, usually without any established trail. This usually requires scrambling over and around rocks, trees, and other natural features. Class 3 canyons and higher also involve the mandatory use of rope to rappel down waterfalls and other steep drop offs. There are often other special challenges as well.
- The exit: reaching and then following a trail (often well-established) back to a vehicle
Like other hikes, canyoneering involves the inherent risks of outdoor activities. These include:
- Remoteness (no one nearby to give or find help should something happen)
- Exposure (heat, cold, etc)
- Water and food availability
Canyoneering also involves additional challenges and risks beyond normal hiking -- these usually occur during the descent phase when the canyoneer is within a drainage. The ACA rating system attempts to communicate the major types of challenges and risks present in a particular canyon. Perhaps the most important differences for an experienced hiker just starting canyoneering are
- Inability to reverse: Many jumps, slides, climbs, and rappels are irreversible. Once a canyoneer has passed one of these obstacles, he cannot return the way he came if he encounters a more difficult obstacle further down canyon.
- Rope work: In addition to needing the appropriate skill and gear to descend vertical drops, a canyoneering group must also know how to anchor and retrieve the ropes used for descent because most canyoneering trips are one-way down the canyon. Furthermore, canyoneers must be sufficiently familiar with these skills to perform them well even when cold and exhausted.
- Water: In addition to hypothermia concerns in all canyons with water, class C canyons present special challenges and make most other challenges more difficult.
- More dangerous locations: Flash floods are a substantial danger in most canyons, and there are usually other dangers associated with the nature of the terrain such as falling rocks and uneven terrain.
- Time management: Simply being able to perform certain tasks (like constructing an anchor or rappelling a drop) is not enough; these tasks must be performed in a timely manner to avoid exposure to a number of other risks. For instance, in a canyon like Cerberus with around 30 rappels, if each rappel took an extra 5 minutes for each of 6 people in a group, the length of the canyon would more than double.
- Flash floods: While flash floods can be dangerous outside of canyoneering, being in narrow slots with few or no escape options increases the risk due to flash floods substantially in most canyons.
