High Quality Content by WIKIPEDIA articles! Snowcat skiing is off-trail, downhill skiing that is accessed by a snowcat, not a ski lift. Snowcat skiing is essentially about skiing in a natural -- albeit highly selected -- environment without the effort or gear compromise required for hiking into these areas as in ski touring or ski mountaineering. The service is less expensive than heliskiing and is more environmental friendly than heliskiing as some of the snowcats run Bio Diesel for fuel.
