I'd love to start at Portugal, then proceed to Gibraltar and follow the coast of the Mediterranean all the way around until I end up in Morocco. I'd stop in ports along the way to sample the cuisine of Portugal, Spain, France, Italy, the Balkans, Greece, Turkey, Israel, and as many Mid East and North African ports as I could safely enter. This would take months to complete.
Then, I'd plan my northern Europe coastal tour that starts again in Portugal, but goes in the opposite direction, ending (weather permitting) in northern Norway.
