You've heard of mountain biking, but treetop biking? Yes, you totally read that right. Au Diable Vert's unique VéloVolant activity lets you pedal your way down cables suspended between trees at its mountain resort in the beautiful town of Sutton, Quebec.While Quebec's stunning parks offer up lots of biking experiences, none truly measure up to the adventure of soaring in the tree canopy of the province's deciduous forests.Au Diable Vert also promises views of waterfalls and the Green Mountains of Vermont.
