From Lowest To Highest (FLTH, Germany Edition) connects the two aforementioned topographical features to one another via a nearly 1000KM long route. This route begins somewhere 70KM north of Hamburg, in the middle of nowhere at a flat, unassuming, fenced off patch of land marked as "Lowpoint of Germany". Don't expect anything but starting line thrills here, because the flatness itself is as uninspiring as it is obvious.

The trail uses existing routes to produce a long distance trail which roughly follows the boundary between Broxtowe Borough and Nottingham City.
