Hundreds of snorkellers come to swim in the beautiful waters of Hanauma Bay all hoping to see some spectacular underwater life. It was originally the crater of an ancient volcano that flooded and has now become a protected marine life conservation area (meaning you have to watch a 9 minute video all about protecting the sea life before you can even enter). Other than the amazing sea life you get to see, I love the fact that there are areas called sandman's patch, toilet bowl and witches brew...I know, it doesn't take much to please me!
