Explore the beauty of the fiord on a vessel that’s purpose-built for the best daytime viewing. Set off on a day-trip that includes a delicious lunch, complimentary tea and coffee, and a visit to the Milford Sound Underwater Observatory. Climb aboard a smaller vessel at the Milford Sound Cruise Terminal to discover more of the fiord on an authentic and insightful experience. Get within touching distance of impressive rock walls and waterfalls.

Join the skipper in the open wheelhouse and say hello to the native seals basking on the rocks as you pass them by. A knowledgeable local guide will ensure you discover the wildlife, nature, and history of this remarkable sanctuary.

Take a break for a picnic lunch. Choose between a regular, vegetarian, vegan, or gluten-free picnic option that includes a wrap, cheese, and crackers, seasonal fresh fruit, crisps, a cookie, and a small chocolate bar. Visit the Milford Sound Underwater Observatory, New Zealand's only floating underwater observatory for an experience unlike any other. Hidden under the surface in Harrison Cove in the middle of Piopiotahi Marine Reserve, the Observatory enables you to experience a different perspective of the fiord.

Descend 64 steps (10-metres) underwater into a large, fully air-conditioned viewing area and peer out through large windows at the deep underwater haven. Unlike an aquarium, the fish are free to come and go; it’s the people who are contained.
