Discover underwater wonders at two terrific snorkeling sites and then wander through a historical landmark on this half-day tour in Curacao. In Caracas Bay, come upon a famous sunken tugboat, where trumpetfish, angelfish and tube coral swirl around the hull, and then snorkel in the shallow terraces of a beautiful and calm bay for more colorful sea life. After drying off, visit Fort Beekenburg, built to keep out pirates, and capture wonderful views of Spanish Water harbor.
