Most of Ecuador's cruising options are centered in the Galápagos, where dozens of yachts and catamarans offer 1- to 2-week tours to the archipelago's attractions. These cruises are focused on the fascinating fauna, and most offer the option of snorkeling or scuba diving, whereas some boats cater explosively to scuba divers.
