If you’re ever in Hawaii on the island of Oahu I recommend a visit to Hanauma Bay (photo: http://panoramio.com/photo/25584412) for snorkeling. It is a beautiful spot and there’s a lot to see within an easy walk down from the main road and a short swim to the reef. There a prettier places in Hawaii but this one is the most accessible in Oahu. Get their early to avoid the crowds. Google has now added a tour of the reef to their street view site. Here’s a link to let you virtually swim around.http://goo.gl/L673j
