Beyond the incredible shopping and dining, Siam Paragon also hides this aquatic marvel. Nestled right beneath the bustling Siam Paragon, this isn't just any aquarium—it's one of Southeast Asia's largest, offering an immersive journey into the underwater world. You'll find everything from majestic sharks gliding overhead in the ocean tunnel to playful penguins in their icy habitat, and countless vibrant fish in between. It's a fantastic spot for all ages to get up close with marine life and learn a bit about our planet's fascinating oceans.
