A geyser made of ocean
Thousands of years ago, molten lava poured into the sea here and cooled into a network of tubes. One of them ends in a narrow vent just below the clifftop, and when a swell rolls in, the ocean is forced through the tube and erupts skyward in a hiss of spray, sometimes 30 feet high. Time it right and you feel the mist on your face from the lookout.
Halona means lookout or peering place in Hawaiian, and the name has never stopped being accurate. From the railing you scan one of the most dramatic stretches of coast on the island: black lava benches, deep blue water and, from roughly December through April, humpback whales breaching offshore.
The beach from the movies
Tucked beside the blowhole is Halona Cove, a pocket of golden sand between lava walls. Hollywood made it famous in 1953 when Burt Lancaster and Deborah Kerr filmed the surf-swept embrace in From Here to Eternity here. Locals still call it Eternity Beach.
Your guide will point out the safest vantage points and explain how the swell direction decides the show. Some days the blowhole whispers; on a good south swell it roars. Either way, the coastline alone is worth the stop.
Halona means peering place. Stand at the rail and you understand the name instantly.
