Immerse yourself in the breathtaking beauty of Milford Sound during a boat cruise led by a naturalist guide. On board a smaller-sized vessel than typical Milford Sound cruises, enjoy indoor and outdoor observation decks that provide fantastic photo ops of this famous South Island natural wonder inside New Zealand's World Heritage–listed Fiordland National Park. Stay on the water longer than most other tours, and get close to the waterfalls and other natural features that give the sound its nickname, the Eighth Wonder of the World.
