Firefighters were called about 4:40 p.m. to the shoreline below the 6600 block of Del Playa Drive, fire Capt. Dave Zaniboni said.
The victim, believed to be in her early 20s, had fallen 30 to 40 feet and sustained moderate injuries, Zaniboni said.
Her name and further details on her condition were not available.
The call was one of many Santa Barbara County crews responded to Saturday during the unsanctioned Deltopia street party in Isla Vista.
Most of the other calls were for alcohol overdoses, Zaniboni said.
