The S-Turn rapid is a technical and powerful Class IV+ drop characterized by a sharp S-shaped navigation through constricted boulder gardens and powerful hydraulics. Paddlers must execute precise moves to thread between large, sharp rocks and avoid potentially dangerous holes, with the crux of the rapid involving a sharp left-right move that requires immediate route selection and strong boat control. The rapid demands advanced skills and presents significant consequences for missed lines, with potential for pin situations and violent recirculating features.
