Tipped to be one of the most visited attractions on the island, Underwater World Langkawi is an educational activity hub like no other. Home to a whopping 200 species that include marine and freshwater creatures, the Underwater World Langkawi is also the largest aquarium in the country. Ideally situated near the Zon Shopping Centre, this family-friendly venue boasts rockhopper penguins, harbour seals and the biggest freshwater fish in the world, the Arapaimas. Spending an afternoon in the underwater tunnel allows visitors to have close encounters with green turtles, sharks and countless other creatures including massive stingrays. The aquarium's various thematic zones, the Tropical Rainforest, Temperate and Sub-Antarctic enclosures are another reason to visit this larger than life enclosure.
