What is canyoneering? Well, it’s sort of like hiking on steroids. Canyoneering is traveling in canyons (usually narrow ones) using a variety of techniques that may include walking, route finding, problem solving, scrambling, climbing, jumping, rappelling, and/or swimming.
Here is a good explanatory video that gives you a flavor of what canyoneering is all about.
