2011 World's Best Diving and Resorts: Aggressor Fleet -- Turks & Caicos Aggressor II

April through January, scuba divers set off from Providenciales aboard the Turks & Caicos Aggressor II for a week of thrilling wall diving along the coasts of West Caicos and French Caye. These sheer walls begin at 40 feet, plunging into the deep blue abyss and include crevasses and ledges that are decorated with huge orange elephant ear sponges, gorgonians and crimson rope sponges. Mid-January through mid-April, snorkelers have the rare opportunity to swim with humpback whales. Whale charters depart from Puerto Plata, Dominican Republic.
