The Vizhinjam Rock Cut Cave is about 17 km from Thiruvananthapuram city. It is a historic spot which was left unnoticed for long time. Vizhinjam Rock Cut Cave basically constitutes the rock cut sculptures of the 18th century in the cave temple at Vizhinjam. The granite cave here encloses a one-celled shrine with a loose sculpture of Vinandhara Dakshinamurthi. The outer wall of the cave depicts half-complete reliefs of the Hindu God Shiva with Goddess Parvathi. Another nearby tourist attraction is the Marine Aquarium at Vizhinjam which houses the world's rarest and most exotic species of invertebrates and fishes.
