Founded in 1976 by conservationist Romulus Whitaker, the Croc Bank is a leading reptile zoo and research centre focused on breeding and conserving India’s crocodiles, gharials, turtles, and snakes. Boardwalks around shaded ponds, interpretive signage, and trained educators make it an engaging, science-forward outing for families, students, and nature lovers.

Located on the East Coast Road between Chennai and Mahabalipuram (~40–45 km from MAA), the Croc Bank features close but safe views of mugger, saltwater crocodiles, gharials, and rare turtles, plus a small herpetology museum and scheduled keeper talks/feeding sessions (check timings). Expect good shade, basic cafés, and a clean, well-managed campus easy to pair with Mahabalipuram Shore Temple and ECR beaches for a full coastal day.
