An elevated downhill transport system is provided with a cable system and appropriate towers to support the cable along a variable downhill course. A single cable only, being necessary, a cable trolley is also provided that prevents the carriage from accidently leaving the cable during any part of the descent. The system relies on no outside power except gravity for the descent. Ascent can be provided for by pre-existing ski lift equipment. The entire system is simple, inexpensive and transportable, lending itself to portable operation.
