Underwater World Pattaya is not just a typical aquarium; it’s an immersive marine habitat showcasing over 5,000 sea creatures across more than 200 species. The aquarium is thoughtfully designed into thematic zones, each replicating different aquatic ecosystems found around the world. This allows visitors to explore the diversity of marine life, from coral reefs teeming with colorful fish to the mysterious depths inhabited by giant freshwater species. Walk Through the Spectacular Acrylic Tunnel The crown jewel of Underwater World Pattaya is its spectacular 100-meter-long acrylic tunnel. This curved walkway plunges visitors into the heart of the ocean, providing a 360-degree panoramic view of marine life swimming all around. Walking through the tunnel feels like being inside a giant aquarium, where sharks, rays, and schools of exotic fish glide gracefully overhead and alongside you. The tunnel’s innovative design uses crystal-clear acrylic that is both durable and safe, ensuring visitors feel close to the sea creatures while remaining completely protected.
