Los Angeles County Fire officials responded to the area known as Sacred Cove shortly before 8 p.m. just as the sun was setting, making it a night rescue.
Officials say the 23-year-old man was in the cave just as the high tide started to rise.
AIR7 HD was over the scene as that person was hoisted up from the rocks and airlifted to the hospital with minor injuries.

The popular scenic area has been the scene of fatal incidents. Two swimmers died in separate incidents back in 2014.
Locals say this rescue was a reminder of how dangerous those waters can be.
"There's been a lot of incidents and I guess people just don't understand and keep going down there," said Torrance man Hector Franco.
Officials said the man did breathe in water but his exact conditions were unknown.
