This is the Portuguese interior at its most rugged: rolling hills that merge into one another, woodland, quiet villages and very little traffic. Plenty of views, hardly any people. Vinhais lets you go quietly, but that doesn’t last long.
The day revolves around one steep climb: more than 350 metres up in about 4 kilometres. After that you descend for most of the afternoon, and you’ll feel it in your knees and toes. It’s a long, tough day, so the main thing is to find your own pace.
Segirei is small, and there’s no accommodation listed in or near the village. So arrange something in advance, or choose somewhere earlier or further on.
