Busan Aquarium, Public aquarium at Haeundae Beach, South Korea.

Busan Aquarium is a three-level facility housing around 40 distinct sections where visitors encounter hundreds of marine species. The spaces are divided into different habitat zones designed to recreate the natural conditions of various ocean environments.

Busan Aquarium opened on 7 November 2001 as a joint project between Living and Leisure Australia and the local government, the first major tourism undertaking under South Korea's Private Investment Promotion of Infrastructure Law. It was rebranded Sea Life Busan Aquarium on 1 July 2014 after LLA was acquired by Merlin Entertainments. Since 5 February 2010 it has held a sister-building tie-up with Aqua World.

The aquarium's name changed on 1 July 2014, when it was rebranded Sea Life Busan Aquarium after its operator was acquired by Merlin Entertainments, the world's second-largest attraction operator. Its Korean name remains simply Busan Aquarium. Since 5 February 2010 it has held a sister-building tie-up with Aqua World.

The best time to visit is in the morning when the facility is less crowded and animals are most active. Plan to spend at least two to three hours to explore the different sections at a comfortable pace.

The 80-metre underwater tunnel runs through the main tank, which holds 3,000,000 litres of water. The tank is also visible through acrylic windows, so visitors can see the same animals from two angles. The tunnel is the longest part of the route through the aquarium's 40 exhibits.
