Step ashore at Punta Cormorant’s olive-sand beach with the sounds of sea lions, lava herons, yellow-crowned night herons and blue-footed boobies as you walk around Floreana (Charles) Island. The green mineral you’ll see on the beach is caused by a high concentration of iron and manganese from the same basaltic lava found in Hawaii. As you walk to a brackish lagoon, home to Bahama ducks, common stilts, Galápagos flycatchers and bright pink flamingos, the guides will point out the rich variety of plant life, including morning glories, cut-leaf daisies, mangroves (black, red and white), palo verde and Scalesia. The trail leads to a beach where sea turtles lay their eggs in the powdery sand dunes and sting rays swim in the shallow water. Don’t miss the opportunity to snorkel at Devil’s Crown or Champion Islet, a shallow sunken crater colonized by a brilliant array of colorful fish and coral, white-tipped sharks, sea turtles, spotted eagle rays and sea stars. Return to the yacht for lunch and a brief history of the human history of Galápagos and explain the fascinating story of why this island is sometimes called the Island of Mysteries. In the afternoon, you’ll be able to participate in a thrilling Galápagos tradition - Floreana is home to Post Office Bay, the site where English whaling vessels erected a post barrel in the late 18th century. When you drop a postcard in the barrel, no postage is required. You’ll search through the postcards left by previous visitors, and if you see one addressed to a location near your home, you may choose to take it with you and deliver it in person. Similarly, your note will be delivered by future visitors. Postcards will be provided on board by your guides. Take a Zodiac excursion at Baroness Point to look for sea turtles and rays. If you have an underwater camera, you’ll be busy snapping photos of sea stars and a brilliant array of colorful fish. Return to the yacht for a briefing followed by dinner and a fun filled entertaining pirate themed party – participation is optional.
