This is a roughly 200 mile loop with 50K of vertical gain that circles a large portion of the Great Smoky Mountains National Park.  While it is the most visited National Park in the country, several of these trails see very little traffic, so there will be more solitude than one may expect.  There are several places to start/finish the loop including Sugarland Visitor Center, Townsend, Fontana Dam, Clingman's Dome, Smokemont Campground, & Big Creek Campground.  These are also the easiest crew access points, although crew could access other areas with a little hiking.

Fantastic round in the Bavarian mountains with great trails and a breathtaking view of the Austrian mountains and the Tegernsee.

The crossing of the north face of the Blaubergkopf is very steep and exposed in short passages; the rest of the tour is easy to run
