This trail can be done as a loop, however, a shuttle to the top proves to be a quick fun ride (7.5 miles from top to Ketchum). First 4.5 miles are single track dirt taking you through forest and then out to a bench with a natural slalom course through the sage. The trail will dump you out into a neigborhood above Sun Valley with 3 miles back to Ketchum on the the rollerblade/bike paths. The single track is smooth and fast.
How to get there:
From Ketchum, ride towards and past Sun Valley and continue north east for a few miles until you hit the first major dirt road that heads east. Take the dirt for a mile or so until you hit the corral on the south side of the road. The trail starts west of the corral.
