Explore Prague’s mesmerizing Jellyfish World with over 30 species, a Guinness-record spherical aquarium, and a refreshing lemonade—perfect for curious travelers.

If you’re in Prague and looking for a unique, visually captivating experience that’s different from traditional museums or zoo visits, The World of Jellyfish might catch your eye. This attraction offers a chance to explore the mysterious world of jellyfish through a series of aquariums, including the world’s largest spherical tank.
What we like most about this experience is the impressive scale of the spherical aquarium, which Guinness World Records has officially recognized. Its giant size makes it a striking centerpiece and offers mesmerizing views that are perfect for photography or simply marveling at these delicate creatures.
However, some visitors have noted that the entire experience can be quite brief—around 10 to 15 minutes— and, surprisingly, the variety of jellyfish isn’t overly extensive, with some reviews mentioning that many are quite small or that not all are active. So, if you’re after a long, immersive tour, this might not fully satisfy your curiosity, but it’s a solid stop for a quick, visually stunning outing.
This tour suits travelers with a curious mind, an interest in marine life, or those seeking a quick, Instagram-worthy experience. It’s also a nice addition if you’re exploring Prague’s more unusual attractions and want to take a break in a modern, engaging environment.

The World of Jellyfish is conveniently situated on the roof of the Arkady Pankrac shopping mall, making it easy to combine with a shopping trip or other nearby sights. The entry point is straightforward—just exchange your voucher at the ticket counter. The site is wheelchair accessible, which is a plus for visitors with mobility needs.
Your ticket, priced at $16 per person, grants you entry into the complex — a space spanning over 700 square meters— and comes with a free lemonade to enjoy after or during your visit. The experience isn’t a guided tour, so you’re free to explore at your own pace, but be aware that it doesn’t include skip-the-line privileges. Therefore, arriving at your scheduled time is advisable to avoid waiting.
The star of the show is undoubtedly the world’s largest spherical aquarium. It’s a jaw-dropping structure where you can see jellyfish swimming in their glowing, delicate forms against a carefully curated audiovisual backdrop. Many visitors describe it as a captivating sight, especially with the video mapping and special effects that enhance the experience.
While the spherical tank offers excellent photo opportunities, some reviews mention that the entire walk-through is quite brief. A reviewer noted it only takes about 10-15 minutes to see everything, which might feel a bit rushed if you’re expecting a lengthy exploration.
Beyond the giant sphere, there are 38 aquariums in total, housing over 30 species of jellyfish. The tanks vary in size, some small and others more spacious, featuring different species with intriguing shapes and movements. The aquariums are designed to provide a close-up view of these creatures, and the audiovisual effects make it more engaging—especially for children or those new to marine life.
The experience garners mixed reviews. Many appreciate the stunning views and the novelty of the spherical tank, but several feel that the overall tour is too brief for the price. One traveler pointed out that “it takes only 10-15 minutes to walk around the entire jellyfish world,” adding that “it’s not worth making a special trip here.” Others mentioned that the small size and limited activity of the jellyfish might disappoint those expecting a more dynamic display.
One reviewer expressed that “it would be good if more jellyfish were alive,” suggesting that not all tanks showcase lively or large specimens at the time of visit. Still, the audiovisual effects, including the video mapping, are praised for adding a wow factor to the visit.

Considering the price, this experience is decent value for a short, visually striking attraction, especially if you’re fascinated by marine life or looking for something offbeat. However, if you’re expecting a detailed, in-depth aquarium tour, you might find it slightly underwhelming.
The main appeal lies in the spectacular spherical aquarium and the audiovisual effects, which can be very captivating, especially for children or those seeking a quick visual fix. But if you’re a dedicated marine enthusiast or prefer longer visits, you might find this experience a bit limited.

This tour is best suited for travelers who want a brief, visually engaging experience that’s easy to fit into a day of sightseeing. It’s ideal if you’re nearby shopping or exploring Prague’s modern attractions. Families with children will likely enjoy the colorful tanks and effects, while couples seeking a quick photo opportunity will find it worthwhile.
It’s also a good choice if you’re curious about Guinness World Records or want a different kind of aquarium experience without the long queues or hefty price tags.

The World of Jellyfish in Prague offers a unique, compact peek into the delicate beauty of these ocean creatures, highlighted by the record-breaking spherical tank. While the visit is short and some might find it somewhat limited in scope, the stunning visuals and audiovisual effects make it a memorable stop—especially for photography lovers or those interested in marine life.
At just $16, including a free lemonade, it’s a reasonable outing for a quick dose of the mesmerizing world beneath the waves. However, if you’re after a more detailed or longer experience, you might want to allocate extra time or look for other nearby attractions to complement your trip.
Overall, it presents good value for a fun, quick diversion in Prague and offers a visually compelling taste of the mysterious jellyfish universe.
