Good for a short visit

The Blue Zoo is a compact aquarium that's worth a visit for an hour or two. While a bit run down and can get overcrowded, crowds move pretty quickly through its exhibits.

It's main feature is the plexiglas tunnel that guides visitors underneath its huge reef tank, which provides close-up views of snaggle-toothed sharks, a huge sea turtle, and hundreds of fish. A moving track helps keep the crowds moving through.

Added bonus: most of the exhibit explanations are bilingual.
