You won’t want to miss this delightful underwater experience available nowhere else on Aruba. Participants wear specially designed diving helmets to tread the sea floor on a custom 375-foot walkway, 20 feet below the surface. Even non-swimmers and those who don’t snorkel can feed the colorful tropical fish, view a sunken Cessna 414 airplane, and pose for a photograph while sitting at the underwater Sea Trek Cafe.
