I read that one of the most beautiful villages in Madeira was Ribeira da Janela, by the same river, but with an altitude of more than 500 meters.
Well, I didn't visit, didn't see its camping park( the only one in Madeira, they say) only crossed the river's mouth at sea level, when travelling from Seixal to Porto Moniz. Next time...
It's remarkable the contrast between the old road that follows the north side of the island and the modern one.
Seixal provides good sights but it is a pity that, for security reasons, most sections of the old road are closed to traffic.
