Hanauma Bay is considered to be one of the best snorkeling spots on the island of Oahu. While I didn’t get the chance to snorkel there myself, I still had the opportunity to take some photos of its stunning beaches and coastline. You can find Hanauma on the southeastern coast of the island and its location on what you could say is the “tip”(well, to be accurate, Hanauma is actually a marine embayment formed within a tuff ring) makes it all the more striking when seeing it in person and looking at it in photographs.
However, what I think is even more amazing is looking at aerial shots of it. On “ground level” Hanauma looks like a typical beach park-palm trees, sand, water, land formations in the background. Yet from the air, you get a whole different perspective. About 3.9 million years ago, the Wai’anae volcano created the island of Oahu. The Hanauma Crater was created about 32,000 years ago during the Honolulu Volcanic Series, the latest and perhaps final some believed, volcanic activity to occur on Oahu. The volcanic vents that formed the crater ended up on the sea floor. Wave erosion eventually cut through the low, southeast wall of the crater, thus forming the current bay.
