Surprise rapid is a technical Class IV drop with a complex boulder garden that demands precise maneuvering between sharp, closely-spaced rocks. Paddlers must navigate a tight entry line that quickly transitions into a series of powerful diagonal hydraulics and pour-overs, with minimal margin for error and significant consequences for missed lines. The rapid's namesake is its deceptive complexity, which can catch even experienced boaters off-guard if they do not scout and choose their route carefully.
