Sindhudurg Fort

Built by Shivaji and dating from 1664, this monstrous fort lies on an offshore island and can be reached by frequent ferries (adult/child ₹90/50, 8am to 5.30pm), which depart with a minimum 20 people from Malvan’s harbour. It’s not as impressive as Janjira up the coast, and today lies mostly in ruins, but it remains a powerful presence. You can explore its ramparts and the coastal views are impressive. Boat operators allow you one hour on the island.
