INS Chapal is a warship which has been converted into a museum and now open for visitors. You are shown a short film about the life on the voyage and you get to explore the entire width of the ship to get a glimpse of the voyager’s life. Alongside is the Karwar Aquarium which houses a wide variety of fish. I initially thought it would be nothing great but the sheer variety surprised me. Both these are just on the Tagore Beach, so you could couple a visit to these places along with the beach.
