An elaborate network of aquarium passages beneath the Atlantis resort, themed as if visitors are walking through the excavation of the lost city of Atlantis. The aesthetic is unashamedly Disney; the aquaria themselves are top-class — eight million gallons of seawater, more than fifty thousand fish, twenty exhibits and viewing tunnels you walk through.
The largest tank holds hammerhead sharks, manta rays, and a tornado of barracuda. Free for Atlantis guests; non-guests pay a steep day-pass that also includes the Aquaventure water park. Allow two hours. The cheaper alternative is the marine-life centre at the Atlantis Marina Village which has more modest tanks but free admission to the public arcades.
