Once upon a time we sailed Panama-Galapagos-Peru-Chile-Juan Fernandez-Easter-Pitcairn-FP.
The sail from the Galapagos all the way to Valparaiso is against the current and the light wind
, so it is a bit of a study in masochism. But I'd do it again. Despite the negatives upthread we enjoyed Peru, although it is not the easiest/most welcoming. From Arica down to Valpo we found a warm welcome every place we stopped.
And it gives you a nice sail from the Chilean coast out to the islands.
It is certainly 'against the grain' to sail down that coast, sort of like sailing up the US Pacific coast. And there are good reasons for most people not doing it that way. But if you don't mind the extra work
and the contrary nature of the route
then it can be quite nice.
