Kerala possesses one of the most connected transportation networks in India, necessitated by its dense, evenly distributed population. The state features four international airports: Thiruvananthapuram (TRV), Cochin (COK - the world's first fully solar-powered airport), Calicut (CCJ), and Kannur (CNN).
The road network is extensive, with National Highway 66 running parallel to the coast, connecting the state from north to south. Public transit is heavily reliant on the Kerala State Road Transport Corporation (KSRTC) buses and an extensive private bus network.
The Indian Railways network traverses the entire length of the state. In urban centers, the Kochi Metro provides modern rapid transit. Additionally, Kerala is pioneering inland water transport with the Kochi Water Metro, an integrated water transport system utilizing battery-operated electric boats.
