The day we went out, it was glorious. The sun was shining and it wasn't too windy. There were a lot of people on the boat but we didn't mind standing outside during the hour boat ride out to the crater... but I'm sure there were seats inside, we just didn't bother looking. The crater was pretty cool and the water was cool and refreshing. I was a little disappointed with the sea life. I guess I expected to see more than two kinds of fish (one yellow, one black) and more colourful coral and other sea creatures. Oh well. We saw turtles in the water on the way back to the marina. The crew were great and the BBQ lunch was delish!
