I have wanted to make this pilgrimage since I read “Canterbury Tales” in high school. I hope I can do it before I am too old to do it.
I walked it a few years ago, and I saw an 87 year old man walking it! It took him a bit longer than the rest of us, of course...but if people go slowly and carefully, even pretty elderly people can do it. I saw several people in their 70s, although the majority were probably in their 30s or 40s (not to mention the youth groups that come out to do part of it every summer).
Several people do die on the Camino every year, sometimes from heart attacks (there are several steep climbs) and sometimes from things like being hit by a car at one of the places where the Camino crosses a highway.
But it’s an unforgetable, important thing, and you should definitely make firm plans to do it.
