Board a transfer boat that ferries you out to the waiting semi-submarine, the Seaworld Explorer. Step down into the hull of this unique boat, entering the underwater observatory lined with viewing windows. Settle in to a seat in air-conditioned comfort and enjoy views that only snorkelers and SCUBA divers are typically privy to.
View the spectacular Arashi Reef, home to a variety of marvelous coral formations and many varieties of tropical fish. Listen to marine expert guide talk about Aruba's marine environment as the skilled captain maneuvers the boat for the best views.
Next, visit the wreck of the 'Antilla,' a 423-foot (128-meter) freighter of German origin that was destroyed in World War II. This ship, which lays on its side, partially submerged, is the largest wreck in the Caribbean and is home to abundant wildlife both above and below the water.
After leaving the wreck, enjoy a leisurely cruise back to shore. Watch the underwater world stream by and feel free to ask your guide any questions before heading back to shore via the transfer boat.
