The "Heilbronner Weg" between Rappensee- and Kemptner Hütte is the oldest and most famous ridgeway in the Northern Limestone Alps. It leads in above 2500 meters high over the main ridge of the Allgäu Alps. Narrow rock paths, ladders, bridges, rope-secured sections and breathtaking views give the "Heilbronner Weg" its unique character.

The route takes you around the perimeter of Manhattan island in New York. You can start anywhere on the perimeter. On the west side of Manhattan you can follow the Hudson walkway all the way, then loop along the tip of downtown by Battery Park walkway and past the Staten Island ferry stop, this then connects with the East river walkway which takes you all the way up the East side. Then run all the way up to 125th on the east side, cut into Adam Clayton Powell and run north until it dead ends. Take a left on 155th and pick up the Harlem River Drive bike/pedestrian path (on your right).
