In Captain Cook Bay on the Big Island wild dolphins can be seen on a daily basis about 7 am. You can enter the bay and meet up with the dolphins by swimming across the bay towards the large statue memorial to Captain Cook. When the dolphins arrive please do not feed or touch them. It is safest to keep your hands down by your side.
Dolphins are intelligent and curious creatures.
They will investigate you and swim along with you. To get the most of your adventure it is best to have a snorkel, mask, fins, and a disposable waterproof camera. Captain Cook Bay is easy to find and can be located on any island map. This doesn't seem like something to be offended by. What's most important is to just have a good time while you're in paradise, whatever you choose to do for fun.
