If you are looking to do some snorkeling at this awesome nature conservatory, then this is the way to go. No need to make a reservation. The driver picks you up at your hotel in a shuttle that seats up to 10. Then drives you over to the Bay. Our driver made great time getting there so he pulled over and gave us our snorkel gear to ensure our fins fit properly. He drove into the park and got our timed passes to get in. We got off and got in line for the 7:10am entry. Paid our $25 each to enter the bay and then took the shuttle down to the beach. Had a great time. We also rented chairs and a beach umbrella for the time we were there. Driver picked us up at 12 noon and drove us back to each of our hotels. This was the best hassle free way to experience Hanauma Bay. Would definitely recommend.
