This natural ocean geyser is caused by breaking surf forced through a lava tube and exploding upward into the air. Burt Lancaster and Deborah Kerr shared a famous beach kiss in the small cove next to the blow hole in the movie, "From Here to Eternity." A roadside lookout is directly above the blow hole. Located 2 miles past Hanauma Bay on Kalaniana'ole Highway, just before the turnoff to Sandy Beach.
