Kerala's monuments are highly accessible due to the state's robust infrastructure.
Visitors can reach various sites via four international airports: Trivandrum, Cochin, Calicut, and Kannur. The Southern Railway network runs the length of the state, connecting coastal forts and inland palaces. The Kerala State Road Transport Corporation (KSRTC) operates extensive bus routes, while modern highways connect major heritage zones. Uniquely, many monuments in the backwater regions (like the Krishnapuram Palace or Bolgatty Palace) can be accessed via inland waterways. The Kochi Water Metro is a modern addition, linking islands with historical significance via electric ferries.
