This route is a unique take for the Mid South of the USA.  It is based on the infinity loops typically run on volcanos in the Pacific Northwest or in other parts of the world.  To have such a possible route in this part of the country is rare.  The infinity loop is shaped after the infinity symbol looking much like a figure eight. It involves an up and over of a mountain from one side to the other.  A complete circumnavigation of the mountain, and then repeat the up and over in the opposite direction.

The Virgentaler Sonnseitenweg is, as the name suggests, made for sun worshippers. There is hardly any other long-distance hiking trail that can guarantee you as much sunshine as this one. As part of the hike, you'll roam through several valleys of the Nationalpark Hohe Tauern Osttirol, among which is the sunny village of Virgen.

Croatian Hiking Trail (HPO) is the longest and most popular hiking trail in Croatia. It was envisioned and opened by Croatian Mountaineering Association (HPS) in year 2000 during the 125 year anniversary of organized mountaineering in Croatia.
