Canyons form when a river or creek runs along a weekness in the earth and erodes a deep chasm in the ground.
Canyoning is the sport of exploring these environmental marvels. Canyons tend to form unique little rainforest-like ecosystems with an abundance of ferns and little creatures to keep you entertained.
Technically, canyoning involves swimming, crawling, scrambling and abseiling down waterfalls and creeks with huge cliffs on each side of you. Canyoning is the ultimate combination of outdoor rock sports, lots of abseiling, scrambling and climbing, and crawling like in caving.
Canyoning is one of the harder sports to describe, you have to go out and experience it for yourself; photos cannot do these places justice.
