Hanuama Bay, Oahu
When it's your first time to the island, you have your dreams of escape. If getting away is your plan, plan on the other islands. Oahu with all its beauty is a tourist trap. There are a number of different places where you can snorkel on Oahu, however, the best place is Hanama Bay just outside of Honolulu. You should note that it does get crowded here so you should get there early. Buses will take you there from the hotel strip, save some money and don't bother wasting your time doing the hotel shuttle plan.
