Halona Blowhole

Halona Blowhole is a famous spot beside the coastal road north of Hanauma Bay and south of Makapuu Point. The oddity is where the surf is diverted upward through a hole in the volcanic shelf on the shore. The blowhole works when the surf is up, but may be dormant if the sea is calm which is often the case in summer.

Beside the blowhole parking lot, one also finds an attractive rocky point which juts into the sea.
