Oceanografic: Walk Beneath the Sharks at Europe's Largest Aquarium
Step inside Santiago Calatrava's blinding-white, sci-fi City of Arts and Sciences and into the Oceanografic, the biggest aquarium in Europe, where a glass tunnel puts sharks and rays gliding over your head and beluga whales, sea lions and a dolphin lagoon fill nine themed marine worlds. It is the single most photographed image of Valencia and the closest marquee sight to the cruise terminal, about 12-20 minutes by bus line 95 or a ~12-15 euro taxi. For a first-timer with one port day, this is the regret-if-you-miss-it stop.
