When you think of the biggest indoor water parks, tropical locations or amusement hubs may come to mind—but Germany is home to the largest one! Just 45 miles south of Berlin, housed in a former airship hangar, is Tropical Islands, the world’s biggest indoor water park. Open year-round, this tropical oasis offers a warm retreat no matter the season.
Why Tropical Islands Stands Out
Tropical Islands isn’t just large—it’s a paradise packed with adventure and relaxation. Covering an area big enough for eight football fields, this massive water park offers something for everyone. From thrilling waterslides to tranquil lagoons, both families and adults can enjoy a tropical experience indoors.
For kids, there’s the Tropino Club, featuring waterslides, climbing nets, and remote-controlled pirate ships. There’s also a huge playground and ball pit to keep younger visitors entertained for hours. Meanwhile, adults can unwind in the park’s Balinese-inspired lagoon or relax in one of the luxurious saunas.

Germany’s Tallest Waterslide Tower
Thrill-seekers flock to the 88-foot-tall waterslide tower, which is the tallest in Germany. This exhilarating feature at the biggest indoor water park in the world includes five thrilling slides, like the Double Racer for those who want to add a little competition to their fun. It’s a must-visit for families and adventure enthusiasts alike.
A Year-Round Tropical Experience at the World’s Biggest Indoor Water Park
No matter when you visit, Tropical Islands’ Tropical Sea offers a warm escape. The water, heated to a tropical temperature, lets guests swim under a transparent roof that brings in natural sunlight. Combined, the lagoon and sea cover an area as large as three Olympic-sized swimming pools, providing plenty of space to relax and play.
Beyond the water attractions, Tropical Islands houses the world’s largest indoor rainforest, featuring over 50,000 plants. This lush, natural environment gives visitors the feeling of being deep in a tropical jungle, all within the comforts of the indoor park.
Adult Relaxation at the Biggest Indoor Water Park in the World
While the park is family-friendly, adults seeking relaxation will also find plenty of options. Tropical Islands offers a full-service spa with various treatments designed to rejuvenate the body and mind. Additionally, visitors can venture outside to Amazonia, an outdoor area with pools and sunbathing spots, open year-round. For the best experience, it’s recommended during the warmer months.
Stay Overnight in a Tropical Paradise
Why limit your visit to a single day when you can spend the night at the biggest indoor water park?
Tropical Islands offers a range of accommodations, from themed lodges to tents set up on real sand, all designed to give visitors the full tropical experience. Comfortable bedding, unique decor, and stunning surroundings ensure a memorable stay.
Whether you’re planning a family trip, a romantic getaway, or just a day of fun, Germany’s Tropical Islands, the biggest indoor water park in the world, provides the perfect combination of adventure and relaxation.
