One of the biggest and busiest shipping ports of the region, Vizhinjam is a natural port located 2 km south of Kovalam. It is home to the Sagarika Vizhinjam Marine Aquarium, which uses the image pearl technique to create customised pearls from pearl cement.

While this is the top attraction of the aquarium, it is also a treasure house of marine wealth, home to a number of rare and exotic species of fish. You can observe schools of angelfish, clown fish, seahorses, box fish, cow fish, eels and wrasses protected in large tanks. Another tank, which imitates a reef, has many types of coral.

Sagarika Vizhinjam is open every day from 9:00 am to 5:00 pm, and charges a nominal entry fee.
