Guide / Gear
GearA plain-English tour of the core canyoning equipment — what it does, why it differs from climbing gear, and what to rent before you buy.

Canyoning gear looks a lot like climbing gear from a distance, but almost every piece is subtly different, adapted for a world that is wet, abrasive and cold. Understanding why those differences exist makes you a safer, more comfortable canyoneer — and stops you turning up to a canyon with equipment that was designed for a dry crag and will quietly fail you in moving water.
Canyon water is often shockingly cold, even in high summer, because the deepest gorges never see the sun. A thick wetsuit — 5 mm or more, frequently paired with socks, gloves and a hood — is not a luxury but the single piece of gear that keeps a long day enjoyable and prevents the creeping fatigue of cold. Cold is not just uncomfortable; it slows your hands on the rope, dulls your judgement, and is the quiet cause behind a surprising share of canyon mishaps. Treat warmth as a safety system, not a comfort.
A canyon harness carries a reinforced seat protector, because dragging across wet rock on every rappel would shred a climbing harness in a season. The helmet guards against rockfall and the impacts of jumps. The descender is chosen to control a wet, often muddy rope — wet rope behaves very differently from the dry rope a climber knows, and the right device gives you the friction to descend smoothly.
Most canyoneers also carry a double cowstail — two short, shock-absorbing lanyards that let you clip safely into anchors, especially at the cramped, exposed stances where you change over from one rappel to the next. A whistle for signalling over the noise of water, a knife to deal with a jammed or entangled rope, and footwear with grippy, draining soles round out the personal kit. None of it is exotic, but every piece earns its place by solving a problem the canyon will eventually present.
Canyon ropes are semi-static — low-stretch, unlike the dynamic ropes used to catch climbing falls — and built to resist water. You carry a working rope sized to the longest rappel, plus a backup. Redundancy is not optional in a place where a stuck or cut rope can trap a whole team. Many parties also favour a specific releasable rigging system at the top of each drop, so a rope under load can be lowered or adjusted from above if someone gets stuck — a technique that has no real equivalent in ordinary climbing.
The canyon bag itself is purpose-built: a tough sack with holes in the base so it drains and does not become a dead weight full of water, worn so it hangs below you on rappels rather than pinning you to the rock. Inside, the discipline is to seal anything that must stay dry — first-aid kit, a layer for emergencies, food, phone — in a genuine dry bag, because in canyoning the question is never whether your pack will be submerged but how often. An emergency shelter or storm shrug and some high-energy food weigh almost nothing and matter enormously if a descent runs long or someone gets hurt.
Wet, gritty, sometimes muddy use is hard on equipment, so canyon kit needs more attention than dry-land gear. Rinse ropes and hardware in fresh water after abrasive or muddy descents, dry everything out of direct sun before storing it, and inspect ropes and slings for cuts, glazing and stiffness — wear that semi-static rope hides better than a fuzzy dynamic one. Retire anything safety-critical at the first real doubt. The cost of a new sling is trivial next to what it protects, and a canyon is the last place to discover that a worn anchor sling has finally given up.
