Alex T. 's review, Oahu tours & activities, fun things to do in Oahu | HawaiiActivities.com

Great but not spectacular.

The submarine experience was nice. The inside of the sub was cool and comfortable. The only downside was that I was expecting to see the ocean floor teeming with fishes and corals which was not the case. Instead there were deliberately sunken ships and airplane ruins that served as artificial reefs or the ocean floor would have otherwise been bare. Didn't see any natural corals. But I guess it's not the fault of the tour though their ads were a bit overhyped and misleading with colourful fishes so you would tend to over expect. A fun and unique activity nevertheless for first timers!
