Underi
Island Historic maritime fort island near Alibag, Maharashtra
An offshore fort near the Konkan coast, Underi is approached by boat from Alibaug; visitors come for short coastal excursions, fort ruins and views of shipping lanes.
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.
