The Römerkanal-Wanderweg follows the historic route of the Roman aqueduct that once supplied water from the Eifel region to the city of Cologne (Colonia Claudia Ara Agrippinensium). The route runs approximately 120 km from Nettersheim to Cologne and is characterized by a generally gentle gradient, reflecting the engineering requirements of a gravity-fed water system.
The route begins in Nettersheim, near the source region of the Roman aqueduct, and follows the marked Römerkanal-Wanderweg through a mix of forest trails, gravel paths, and occasional paved sections. It passes through rural areas, small villages, and open landscapes before reaching the urban environment of Cologne. The finish is defined in central Cologne (e.g., Cologne Cathedral / Dom area), representing the historical endpoint of the aqueduct.
The route is not a continuous technical trail but consists of rolling terrain with frequent small climbs and descents. Total elevation gain is approximately 1,100 m. Navigation is generally straightforward, as the trail is well marked, but a GPX track is recommended for accuracy and consistency.
This route is notable for its historical significance, following one of the longest Roman aqueducts north of the Alps, and for its runnable profile, making it suitable for long-distance efforts.
