We are planning a road trip to retire our rusty motorhome to our land in spain, we want to use the trip to visit as many ancient stones/caves/art as humanly possible in 7 days, before flying home from barcelona, if you were to do this where would you recommend along the way, kind of in a north to south direction, i used to have the megalithic european but sold it during hard times, sad days long gone thankfully, but due to lack of book i will need towns or location details please so i can plan the best route before we go, thanks in advance :)
