Varkala Aquarium has a decent collection of fishes in a number of large sized that can be viewed from a walkway that spirals upwards. One can find a number of species including Karimeen, Pirahnas, Eels etc. The aquarium also has a 3D theatre where information about more species of fishes is given using the 3D technology. The aquarium is a perfect attraction to see over a day-long picnic.
