25 Items to Fill Up Your Bucket List in Oahu

02 Halona Blowhole

Also lying on the east side of Oahu, the Halona Blowhole is a natural wonder with connections to the island's volcanic history. This lava rock formation acts like a geyser on high tide, windy days. As the waves roll in and cross the lava rock, water from the sea shoots as high as 30 feet into the sky. Some of the most violent waters in Hawaii churn along the coast due to strong currents and huge waves. Visitors often see whales spouting along the surface of the coastal waters between late December and early April. Located just 20 minutes outside of Waikiki, the scenic drive to the site along the Kalaniana'ole Highway is enjoyable, offering various photographable opportunities.
