Coastal grotto

 is a small cave in Point Lookout. It is where Plik lives and holds a "safari" of sorts with ghouls as the hunt. There are also two men, Jacob Humboldt and Rip Smithy, in the safari chamber, who will most likely die by the end of the safari. It only has one interior section.

Exterior
There is a buoy outside, just east of where the door to get inside is. The door itself is up the cliff side and you'll need to climb your way up. Also, there are some swamplurks nearby, so take them out first before you go inside.

Interior
Inside there is a long tunnel that leads you to Plik. Before reaching him, you'll find his room with a bed, a desk, and, his journal. If you start the quest, you'll be able to enter the safari chamber. The safari chamber is a large room where ghouls come out from all sides when you hit the button in the middle of the room.

Notable Loot

 * Mini Nuke
 * The Dismemberer
 * Ghoul Ecology perk (by reading Plik's Journal)
