Halona Blowhole is located next to one of the most beautiful and secluded secret beaches on Oahu. While on Ohana Circle Island Tour you will be able to peer down at this beautiful cove and it will definitely warrant a visit back during your vacation. Come early and you will be able to see all of the turtles that love to spend the morning hanging out on this beautiful beach. To get to Eternity Beach, also knows as Cockroach Cove, park at Halona Blowhole and you will find a path located where the parking lot meets the main road. Enjoy.
