Hop aboard a transfer boat departing from Oranjestad's De Palm Pie to be taken out to the Seaworld Explorer. Meet your guide, who will share historical and ecological facts about the sights as you travel.
With dry clothing, you get views from the vessel's glassed-in, submerged viewing space of Arashi reef, teeming with tropical fish and other marine life. In contrast to snorkeling, during the submarine tour you can hear insightful commentary from your guide about the types of coral and fish you see.
The next stop is the Antilla, a 423-foot (128-meter) German ship sunk during World War II. Snap photos of the colossal boat and its marine inhabitants, while your guide details history of the ship.
After 90 minutes, you return to shore by boat.
