My plan is to fly into Perpignan 1st week of Sept, hop over a small pass into Spain then down to Barcelona to visit a friend then fly back.
The whole trip is though the Catalunya region, even though it is spread over 2 countries. The food is really great, less fussy and simpler than typical French meals which is a good reason to eat out.
The direct route is quite short so I expect to do some exploring around.
The only issues at the moment are the heat and forest fires.
