I could leave this to someone who saw more forts or maybe just let India pick the ones they want to inscribe first, then get it inscribed, and finally visit. Well, I figured since I'm already at Goa I may as well do a short detour to Sindudurg Fort and tick this off - only that Sindudurg Fort is CLOSED!! One is supposed to supposed to get a boat tour from Malvan 8:00 AM to 5:30 PM daily but, no, this wasn't possible. The official website still talks about it being open too. I thus think someone will visit the forts near Mumbai and tell you more about the actual forts. Officially you take a tour when it starts, it then gives you ~1h fort time to explore before taking you back.

This "must-visit destination" doesn't seem very must-visit either so I don't feel sad about missing out. When I got to the Malvan beach (which is brown and dirty by the way) you can also do parasailing or jetsking to get closer - neither I wanted to do. The pictures I saw online just make out large walls around the island which is otherwise rocks.

By the way I did NOT hire a driver from Goa and instead went to Kudal by train and took an auto-rickshaw from there which means you'll get to Malvan in less than an hour. It also saves you tons of money. You can also combine this with the Dutch factory fort at Vengurla (currently tentative) if you want.
