Discovery World Cruises? MV Discovery literally travels all over the world. Book your Discovery Cruises to Alaska, Africa, Antarctica, Australia, Central America, the Galapagos, New Zealand, the Panama Canal, South America, South Pacific, Europe and more. Every year her voyages seem more and more thrilling. Tours become extraordinary vacations where you feel like you may have stepped back in time, like a visit to the adobe city of Chan Chan, the largest pre-Columbian city in South America, covering an area of 11 square miles. Board Discovery Cruises as it traverses one of the greatest engineering marvels in the world's memorable passage through the Panama Canal.
