Shark diving has always been on my bucket list, so when we booked our trip to Hawaii, this was the first thing I looked for. The staff was awesome and very knowledgeable about the sharks and the area. The cage was big enough for all people and the 20 minutes in the water was plenty of time to get amazing views at these creatures! The only negative thing I have is that the website says you may see several types of sharks including hammer heads, but we were told we would only see Galapagos sharks. However, that wasn't even a concern once I was in the water with them.
