The sea cave is a location in Point Lookout, entered through the wrecked seatub or the well outside the Ark and Dove Cathedral.


The sea cave is inhabited by swamplurks, mirelurk hunters, and swamplurk queens. Tribal leader Jackson uses the cave to communicate with a hologram of Professor Calvert. He can be found all the way in the back of the subterranean cave.

Notable loot


  • In the final room you may occasionally hear splashing of items dropping into the water pool, this is due to the final room being based below the graveyard, and every so often a skeleton will fall from the roof of the cave.


The sea cave appears in the Fallout 3 add-on Point Lookout.
