Underi at a Glance#
Address: Underi Island (near Alibag), Raigad district, Maharashtra, India
Hours: Open to the public (no formal hours)
Admission: Free (no formal ticketing for visiting the island/fort)
How to Get to Underi#
Boat from Alibag, Revdanda or Mandwa. From Mumbai, take the ferry to Mandwa or a road transfer to Alibag and then hire a local boat for a 20-40 minute trip (times vary with landing site and sea conditions). No formal docks or scheduled public services; arrange a private transfer and confirm conditions with the skipper.
Tips for Visiting Underi#
- Arrange a local boat from Revdanda, Alibag or Mandwa rather than attempting to approach independently-local skippers know the currents and safe landing spots.
- Visit at low tide if aiming for photographs of the fort's foundations; high tide can obscure sections of the shoreline.
- Combine a trip with nearby Khanderi (Kundvar) island to see the twin Maratha-era sea forts that once guarded Mumbai's approaches.
Best Time to Visit Underi#
Best visited in the dry winter months (November-February) when sea crossings from the mainland are most reliable.
