The UK leg includes the Dorset and East Devon Coast (Jurassic Coast) on the way to Portsmouth, but this requires a longer detour.

Climatic Conditions and Route Aesthetics

Depart Davos at 1,560 m altitude; expect alpine weather with potential snow until May. Descending towards Basel, the climate warms.
