A trip to Aruba demands at least one snorkeling excursion. Take a trip to Arashi Beach and spy the California Lighthouse, where the sea plays host to the wreck of the Antilla, a 400-foot German freighter. Red Sail Sports offers full- and half-day snorkeling excursions aboard their custom catamarans. At the other end of the island, Baby Bay's calm waters and soft sand lend themselves perfectly to swimmers of untested ability, while the man-made reef is a hangout for rays, octopuses, parrot fish, and more. For something a bit different, Aruba Bob Snorkeling runs underwater scooter trips to Mangel Halto, home to Aruba's most stunning natural coral formations.
