Hello, I will ask the same question about Gibraltar and the other ports of call on our cruise in May 2011. What inexpensive things are there to do in Gibraltar and the following ports we are visiting? Tenerife, Canary Islands; Gibraltar, UK Territory ;Alicante, Spain ;Barcelona, Spain ;Marseille, France ;Florence / Pisa (Livorno), Italy ;Rome (Civitavecchia), Italy. We like to walk wherever we can from the ship (if possible) & we prefer to go to nice sandy beaches & swim (not into snorkeling, just clean clear water swimming). Wherever we go at ports, we like to be SAFE and avoid potentially dangerous areas & situations. If we can't find a nearby swimming beach by walking or cheap taxi or bus ride, we then like to just walk to see the sights and get to know the area on foot. Any suggestions you might have & comments on the individual port is greatly appreciated! Thank You for your help!
