Lotte World Aquarium Hanoi marks Lotte World’s first project in Vietnam. It is a space that recreates the oceanic world, housing over 31,000 marine creatures.
At Lotte World Aquarium Hanoi, visitors can immerse themselves in the breathtaking beauty of the vast ocean. Spanning a total area of 9,094 m² and featuring 67 large display tanks, the aquarium is home to more than 31,000 marine creatures across over 400 species. The design draws inspiration from the legend of “Cá Ông” (the Whale God), the deity who protects fishermen at sea; the figure of Cá Ông serves as a symbolic guide for the journey of discovery within.

Visitors can explore a 650-meter-long route winding through various themed zones, such as the Peaceful Village, Ocean Walk, Blue Sea Exploration, and Ocean Plaza. The aquarium is home to Humboldt penguins, sand tiger sharks, sea lions, and Asian small-clawed otters, among others. Notably, two California sea lions made their debut here in May.
A Colorful World of Discovery
In addition to showcasing unique marine life, Lotte World Aquarium Hanoi boasts one of Southeast Asia’s largest curved acrylic tanks. Positioned overhead like a massive dome, it allows visitors to marvel at schools of fish swimming gracefully above them. The facility also features interactive zones where visitors can listen to the sounds of marine life, offering a closer connection to the creatures of the deep. In the “Whirlpool” zone, visitors can admire marine life from a 360-degree perspective. Following the designated route, guests will encounter the “Coral Garden” and “Shipwreck” zones—areas designed by Lotte World to offer diverse and engaging environments. Additionally, the aquarium hosts unique performances such as mermaid shows, magic acts, and interactive sessions with divers; these experiences leave a lasting impression, especially on children.
After a year of operation, Lotte World Aquarium Hanoi has also become a popular venue for special events. The aquarium is located on levels B1 and B2 of Lotte West Lake Hanoi shopping mall. Visitors can access the facility via two entrances: 683 Lac Long Quan or 272 Vo Chi Cong. The aquarium is situated to the left of the mall’s main entrance.
