Padmadurg or Kasa fort built by Sambhaji maharaj to aide in attacking Murud Janjira is located further ahead in the sea from Murud Janjira and can be visited with the help of local boatmen. Kasa fort or Padmadurg fort is in ruins and is very rarely visited.

Padmadurg is one of the sea forts built by Sambhaji maharaj in 1676 in order to control the activities in Arabian sea. It is located in the northwest direction of the Janjira fort at a distance of about 500mts. The sea fort of Padmadurg is not as big as Janjira but still the fort can be visited and enjoyed. Visiting the fort requires taking permission from the Customs. As of now only the local fishermen in Murud access this fort. Padmadurg doesn't have a proper place to dock the boat and one should be careful while getting on and off the boat at Padmadurg.
