I quite like Gibraltar. When I was ten or so my family took a two month holiday driving around France and Spain and while staying in the south of Spain we visited Gibraltar. It’s a curious experience after two months in France and Spain driving across a border and finding yourself back in the UK, only with sunshine. We went up onto the rock, managed to avoid being attacked by the macaques and spent a couple of hours admiring the view. You can actually see Africa from Gibraltar.
