What steep little climbs, and such clear, cool water. A lovely waterfall and a charming village.
Pop into Anna’s grocery shop when you arrive; there are lots of products to discover.

A lovely walk that must be particularly pleasant in summer, as the path winds its way up through the forest and follows the stream.

A lovely walk through the woods along the river. We did this trail in very hot weather, so it was lovely to be in the shade of the trees. There are some good climbs to tackle, offering stunning views
Very well signposted
