I’ve never been to Spain, closest was southern France. I spent 5 weeks in ‘72 and another 5 weeks in ‘76. Traveled all over, and a bit into northern Italy, in the Alps. A beautiful trip is along the Chateau de Loire and especially Chenonceau castle. and Chambord. The gardens at Chenonceau are just beautiful.
Sadly, never been. I have been invited, often, to the region of Provence, Aix-en-Provence to be specific, by some friends of ours. I gather that its also rather besieged these days.
The Loire is another trip, for sure.
