Discover Fiordland’s iconic Doubtful and Dusky Sounds—home to significant historical and conservation sites in New Zealand. This special expedition pairs two of the most remote and spectacular of Fiordland’s destinations (select departures focus entirely on Dusky Sound).

In this compact vacation by sea, explore World Heritage Area Dusky Sound, one of Fiordland’s largest fiords some 25 miles (40km) long and studded with more than 350 islands. Equally impressive, New Zealand’s deepest fiord Doubtful Sound boasts lush rainforests, towering waterfalls and resident populations of New Zealand fur seals and rare Fiordland crested penguins.

Established in 1952, New Zealand’s Fiordland National Park is rich in endemic wildlife, natural history, geology, historical firsts and conservation projects. Expect waterfalls, streams, rivers and fiords enveloped with misty veils that come and go, revealing steep gradients of mountain peaks and sheltered valleys.

Cruise aboard 18-guest Heritage Explorer, a yacht that’s spacious enough for private moments but also encourages making newfound friends. This New Zealand-born ship, with a family-run Kiwi crew and guides, offers kayaks, a hydraulic aft platform, sophisticated food, regional libations, and cabins for solo and paired travelers. Tap into the passion of the biologists, botanists and adventurers that have designed her itineraries that include regular opportunities for citizen science. She is an AdventureSmith favorite for private charter cruises due to her cozy, inviting feel and size.

Visit Luncheon Cove on Anchor Island, where the first European boat was built in New Zealand. Take a short walk or explore along the coastline and be amazed by the birdlife with South Island saddleback, robins, yellowhead and parakeets in abundance on the island thanks to its predator-free status. It was on nearby Pigeon Island that pioneering conservationist Richard Henry was based during his time in Dusky Sound. At Astronomer’s Point there may be the opportunity to walk in the footsteps of Captain Cook and his astronomer William Wales, as it was here that the HMS Resolution was moored during their time in Dusky Sound. Your expedition cruise through Dusky Sound visits some of the most significant historical and conservation sites in New Zealand, as well as offering some of the most majestic scenery in New Zealand as you sail deep into the heart of Fiordland.

Today, explore your way through the waters of Breaksea Sound and Acheron Passage. Your time here may include venturing into Wet Jacket Arm where the crew of Cook’s HMS Resolution ended up with wet jackets during their survey work. It is also the site where moose were released, and last seen, in New Zealand. You might like to try your luck fishing for tonight’s dinner, or take the kayaks for a shoreline exploration. Resolution Island is separated from the mainland by the scenic waters of Acheron Passage and at the southern end of the passage you enter Dusky Sound. Be sure to be on the lookout for resident bottlenose dolphins.

After a quiet night surrounded by the nature and wilderness of Fiordland, sail along the Fiordland coast towards the extensive protected waters that are Breaksea and Doubtful Sounds, join your naturalists on deck to spot seabirds including the majestic wandering and buller’s albatross. Breaksea Island guards the entrance to Breaksea Sound, it was here that the first successful island rat eradication program was completed and today Breaksea Island is a protected nature reserve of great significance to the many endangered species which call the island home.

Continue your explorations of the most spectacular scenery in all of FiordlandDoubtful Sound, or the ‘sound of silence’ as it’s also known. Spanning some staggering 25 miles (40km) and holding the title as New Zealand’s deepest fiord, Doubtful Sound with its cloud-scraping, wilderness-cloaked mountains, sheer stone cliffs, waterfalls, inlets, quiet coves and wildlife presents nature on a scale so grand it’s off the chart.
