The island is spread over 2 sq km in length and half-a-km in width. The tea stalls (reminiscent of rural Kerala), a temple, kavu and church are the main attractions. An ancient Parasurama temple, on the banks of the Karamana River, is nearby.
Edayar Island can be reached by ferries. Alternatively one can also opt for a narrow iron bridge near Thiruvallam to walk into the island. Trivandrum International Airport is the nearest airport.
