So this post will be about the atlantis submarine in Waikiki :)
This activity is quite popular among tourists since it's suitable for all ages. First, you go to the Hilton Pier where a boat will escort you to the submarine. There's free shuttle for those who aren't staying in Hilton Hawaiian Village. Then the submarine will go until about 120 ft under the sea.
During your journey under the sea, you're going to see many things like a plane wreck, shipwreck, objects. If you're lucky, you may see sea turtles, sharks, or even whale! (Whale is only available during dec-april)
They give us a boarding pass and a handbook (costs US$5.99 in stores, but we get them for free!) Inside the handbook, there's a checklist of fishes and also a brief explanation about Atlantis and the submarines. Apparently they have 2 tipes of submarines : standard (48 passengers) and premium (64 passengers)
They like to call the premium submarine "The Mercedes of Submarines" (⌒▽⌒)
There's also a map and a safety instructions written.
Here are some pictures I took
Leaving Waikiki. We sat at the deck and it's so windy up there :D
The submarine emerged from the sea
The first display. I don't know what this is actually :/
The baby shark!!!
That's the deepest we'd gone that day
Last, a sea turtle aka honu !
I'm sorry if the pictures I took at the submarine aren't in HD :( the submarine's glass is so thick so it's sort of hard to get an HD picture using iPhone cam.
