Visit Chiang Mai Zoo Aquarium, the first aquarium center in Southeast Asia. The 16,000-square-meter attraction is made complete with a spacious exhibition building and is famous for its 133-meter underwater tunnel where freshwater and salt water tunnels meet. This is the place for nature enthusiasts to fully discover underwater charms and learn about aquatic lives. The aquarium is home to more than 20,000 fish over 250 species from around the world, including rain forests of Asia and Amazon jungle. The glass screens of exhibition are well-designed and made of acrylic to ensure safety and deliver an immersive experience as you observe the marine life. You can join fun activities such as scuba diving and snorkeling to get closer to the fish, and watch the feeding show. Apart from the aquarium, you can also discover other showcases with rare plants and exotic or even venomous animals!
