Aspen, CO - highest disc golf course in the world, and home of the "Kiss the Sky" tournament. Definitely one to make if you've got the time and $$ to travel to CO for a weekend, just for the fun of watching a putter go 1200 feet
From the course directory:
Description: Mountain top terrain at 11,212'. On ski trails, with one 1,500' hole; a bad throw and your disc is gone! Lift ticket/$15. Tremendous scenery. Basically open from May to Oct. Confirm with contact.
