Sweet spot: March, April, May. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know

- Bastogne's snow recalls the Bulge exactly as the veterans described it; Luxembourg's Christmas market glitters across the Pétrusse gorge.
