Nagarjunakonda Island Museum preserves sculptures and reconstructed remains of the submerged Buddhist city that gave the reservoir its name. Boats leave from the mainland jetty for a half day on the island among stupas, inscriptions, and museum galleries. It is the strongest heritage stop at Nagarjuna Sagar and pairs with the dam viewpoint. Confirm boat schedules early; services can thin on quiet weekdays.
- Address: Nagarjunakonda Island, Nagarjuna Sagar Reservoir (boat from mainland jetty)
