Madeira is a mountainous island. This makes for vistas aplenty, some of them vertiginous. A walk we took the other day was along a cliff edge. 

It wasn’t right on the edge, and the path was generous, but it took most of my concentration to focus on the path ahead and not look too far out or down. The few times I did, though, I was rewarded with glimpses of blue sky, white waves and lush greenery.

Soon the trail turned inland, and we followed a steep old road down to the shore. The knees were a bit wobbly at the end, both from the height and the effort. But they made it.
