If you "jump in the triangle" on this hiking tour, you're doing it just right: in three stages, the circular tour leads through the Eifel spring triangle to the origins of the Ahr, Erft, Kyll and Urft rivers. Following the course of the rivers, the route leads through idyllic valleys and up to the "Eifel views" in the German-Belgian High Fens - Eifel Nature Park. Also worth seeing: archaeological monuments such as a double lime kiln or an ironworks, historic castle villages such as Kronenburg and Blankenheim or numerous Roman remains in Nettersheim.

• Stage 2: Blankenheim - Nettersheim | 26.0 km | 9 hours
• Stage 3: Nettersheim - Kronenburg | 25.0 km | 8 hours
