Once in a blue moon, you experience something unforgettable. On Norwegian Aqua™, the newest ship, you might find that a blue moon happens more often than you'd think. In St Thomas, greet the green sea turtles and colourful fish as you snorkel the turquoise waters of Turtle Cove. Tortola is the largest of more than 50 British Virgin Islands and its velvety white sand is legendary. Drive through the capital of Road Town for a glimpse of its culture and charm or hit the beaches, especially The Baths, a geographic wonder of mammoth-sized granite boulders.
