Aquariums

Aquariums aren’t just places to see fish and marine animals—they’ve become immersive spaces featuring underwater tunnels, interactive experiences, never-before-seen species, and dedicated areas for education and research. Sleep under the sea, dine with sharks, or walk through Europe’s longest underwater tunnel in Valencia. Visiting a wildlife park or a traditional zoo is always an exciting and memorable experience. Getting up close to animals that you would never see otherwise (unless you were willing to risk your life) is a thrill. But perhaps the most awe-inspiring encounters happen when the animal's natural environment is water. That’s exactly what modern aquariums deliver. At Reserving, we want you to discover the best aquariums across the UK, Europe, and the world. Because who knows—your next trip to the beach, the mountains, or even a city break might include a visit to one of these marine wonderlands. We help you buy discounted tickets at the best prices and provide all the info you need: whether advance booking is required, the best nearby hotels, and what else to do in the destination city. Let us help you plan your perfect escape.

Why Visit an Aquarium?

We already mentioned one of the best reasons: to explore, learn about, and admire some of the most incredible marine creatures on Earth. These animals live in environments so different from our own—out of sight but always present. Observing them can spark respect for nature, environmental awareness, and a commitment to sustainability. That’s why aquariums are a fantastic experience for families with children. And of course, there’s the fun factor. Today’s aquariums are far more than giant fish tanks for freshwater or saltwater species. They’re full-fledged water-themed adventure parks—with interactive rooms, jaw-dropping tunnels, sci-fi-level visual displays, and even the chance to sleep under the ocean. That’s why you shouldn’t miss out on the great deals available through Reserving. Don’t wait until the last minute—tickets go fast!

Top Aquariums in the UK

The UK is home to some of the best aquariums in Europe. Sea Life London Aquarium is an iconic destination right in the heart of the capital, where visitors can walk beneath shark-infested waters. In Scotland, Deep Sea World offers an awe-inspiring underwater tunnel experience. The National Marine Aquarium in Plymouth is the largest in the UK and focuses on conservation and education. For something different, explore the Blue Reef Aquarium locations, including Tynemouth and Portsmouth.

Each of these attractions makes for a great family day out—and Reserving can help you find discounted tickets and nearby accommodation.

Europe’s Best Aquariums

Heading beyond the UK, some of Europe’s most outstanding aquariums are just a short trip away. The Biarritz Aquarium in France, near the Spanish border, is a must-visit. In Portugal, the Lisbon Oceanarium offers an unforgettable experience—and with Reserving, you can book a city tour that includes Belem and entry to the aquarium. Other European highlights include the world-famous Genoa Aquarium in Italy, the Nausicaá National Sea Centre in Boulogne-sur-Mer (Northern France), Sea Life Paris, and Aquaworld in Crete.

The Best Aquariums Around the World

This section could be called “The Best Aquariums Outside Europe,” since many of the world’s top aquatic centers are in Europe—but there are still countless other spectacular options across the globe worth exploring on your next holiday.

In the US, Miami Seaquarium and legendary spots like the Monterey Bay Aquarium and the Georgia Aquarium are top-tier destinations. In Asia, visit the massive Churaumi Aquarium in Okinawa (Japan), the futuristic Lotte World Aquarium in Seoul (South Korea), or the S.E.A. Aquarium in Singapore. China’s Shanghai Ocean Aquarium also offers an incredible experience.

Heading to South Africa? Don’t miss uShaka Marine World, which spans over 16 hectares. In Mexico, the Interactive Aquarium of Cancún is a family favorite, and if you’re in Australia, the Cairns Aquarium is so spectacular that you’ll want to stay for lunch.
