After a long fall, the shaft ends suddenly in a sloshing, circular pool of salt water. You are pushed, pulled and tumbled through a half-submerged hole in the south wall and then along a close, water-filled tunnel for several hundred yards before being violently ejected from the mouth of a small whirlpool into the surf. The strong current carries you to the north until it plays out.
After regaining your bearings, you spot a nice beach to the west and a tiny island to the east.
