If you've got a thing for fish, it's worth making the trip to Monaco just to come here. The museum is probably the best aquarium in Europe, with 90 seawater tanks and a display of living coral. There's also a display on the work of the late, great Jacques Cousteau, as well as other ocean explorers.
If you're unlucky enough to hit Monaco on one of those 65 rainy days, this is the perfect place to console yourself.
