Canyoning combines hiking, climbing, rappelling, swimming, and navigating through narrow canyons carved by water, creating one of the most exciting adventure sports in the outdoors. However, the same features that make canyoning thrilling also create significant risks. Participants may face foot entrapment in fast-moving water, where a trapped foot can lead to drowning. Rope-related incidents, including improper rigging, equipment failure, and rappelling errors, can result in serious injury or death. Powerful waterfalls and recirculating pools, often called “hydraulics” or “keepers,” can trap swimmers underwater. Cold water exposure and prolonged immersion can lead to hypothermia, even in warm weather. Wet suits are essential, but have hidden dangers.  Flash floods, falling rocks, slippery surfaces, exhaustion, and limited access to emergency rescue further increase the danger. 

In this fascinating episode, Dr. Benny Chen explores the unique hazards of canyoning and the essential skills, preparation, and decision-making required to safely enjoy this challenging sport.
