The KAT Walk (Kitzbüheler Alpen Trail) - the "Long-Distance Walking Trail with Comfort" - travels over six stages across the Kitzbühel Alps and into a fascinating diverse Alpine world. From Hopfgarten, over gentle grassy hills, well-marked routes and always with wonderful panoramic views, 108 kilometres leads us to St. Ulrich in the Pillersee Valley.

Upplandsleded is a 450km hiking trail in Sweden.  The ~113km section between Östfora (Siggefora) and Härjarö is separate from the rest of the trail.

The Black Loop at Bear Run Nature Reserve, rated difficult by the Western Pennsylvania Conservancy (WPC), runs through pines, rhododendrons, maples and oaks, crosses and parallels creeks, and consists mostly of technical, rocky paths with some soft conifer-covered ground, wide double track and large boulder gardens in places. The fist seven miles travels on the parking lot side of the reserve (beginning at the parking lot trail head), while the final (and rockiest) four miles run across the road (Rt. 381), above the train tracks with views of the Lower Yough River.
