Can you imagine yourself hiking up a steep hill, reaching the top of a waterfall, then repelling down the face of a cliff and through the waterfall? Then you should go on a canyoneering trip.
Canyoneering (Canyoning) is a sport in which you explore canyons by hiking, scrambling, repelling, rafting, swimming and waterfall jumping. See Wikipedia for more.
To accomplish the repelling part, you need to know about ropes, carabiners and ASAPs. But if you are not a rock climber, you can still enjoy a canyoneering adventure by going with an experienced outfitter and letting them do the technical parts.
