Canyoning (known in the U.S. as canyoneering) is a sport popular in several countries. It involves travelling down creeks or streams within a canyon by a variety of means including walking, scrambling, climbing, abseiling, swimming and "li_loing" (using an inflatable air mattress). It requires skills in navigation, ropework, climbing, avoiding hypothermia etc.
Typically what separates a canyon from any ordinary stream is the narrow passage created by erosion into bedrock, creating beautiful sculptured walls and spectacular waterfalls.
Canyoning can be treacherous. There are risks associated with scrambling down uneven, slippery surfaces and abseiling in wet, cold conditions. Several fatalities have occurred in this sport as a result of Switzerland in 1999. [1] (http://www.outsidemag.com/magazine/1199/199911hardway1.html)

Several sites contain information about canyons near Sydney:
The Grand Canyon is a colorful, steep-sided gorge, carved by the Colorado River, in northern Arizona.
The canyon, considered to be among the major natural wonders of the world, is largely contained in the Grand Canyon National Park - one of the first national parks in the United States.
The canyon was first seen by a European in 1540, García López de Cárdenas from Spain.
A canyon or gorge is a deep valley often carved from the Earth by a river.
Canyons are much more common in arid areas than in wetter areas because weathering has a lesser effect in arid zones.
The word canyon is generally used in the United States, while the word gorge is more common in Europe and Australasia, though it is also used in some parts of the United States and Canada.
