Really fun - I was really nervous in advance of the tour, primarily about seasickness and claustrophobia. Neither one was a problem. The submarine is very smooth once you go below the surface. There is no rocking at all. But each seat does have an "aloha bag" just in case. I also didn't find it claustrophobic because there are so many windows, and they're looking out towards the open ocean. It made me feel like I was in a vast space. The whole experience was actually a bit like being on an airplane. If you can handle the motion and the type of closeness you have on a plane, you can do this. We signed in at the shop inside the King Kamehameha hotel. You enter the lobby and go a bit to the left and back. It's easy to find. There are bathrooms to use if you need. Then they walk everyone down to the pier where you board a boat to get out to the submarine. The ride is short, about 5 minutes. The boat ties up to the submarine, and they help you board. You'll need to descend a ladder, but someone is standing at the bottom to make sure you don't have any difficulty. Then you take a seat facing a window. The boat stays with the submarine at the surface for the duration of the tour. There's a digital monitor that tells you your depth, which is cool, and each seat has a reference chart of the fish you might see. A guide narrates throughout, providing information about what we were seeing and answering questions. We saw lots of coral and reef fish. They were so beautiful. We also saw 2 shipwrecks! It was cool to get to see that up close, as well as how the wrecks served as a reef. Lots of fish were living inside. The tour went by so fast. I wouldn't hesitate to do this again, I loved it.

EPIC! - awesome tour guide! Great experience - not as Closter phobic as I thought it would be. Very knowledgeable Guide. The walk to the boat on a sandy beach is something to prepare for as you get on a boat to go out to the submarine. We saw sunken ships, many fish and incredibly, a shark chasing thousands of fish!

Wonderful Experience with the Best Guide & Crew! - It was much more comfortable than expected. Being in a confined space is difficult for me. The air conditioning and seat spacing made it a wonderful experience. Steve our narrator was awesome. I would highly recommend this once in a lifetime adventure.

Cancelled due to weather. - I was canceled because of rough weather. Not any one’s fault, just the roll of the dice. The submarine company gave us a timely phone call telling us why it was canceled.
