Doubtful Sound Overnight

Experience Fiordland at its finest with our overnight & multi-day Doubtful Sound cruises aboard the Southern Secret

The Southern Secret is a purpose-built motor cruiser that offers overnight cruises and charters in Doubtful Sound. Stay in one of our five well-appointed ensuite cabins and enjoy the spectacular scenery in comfort. An overnight cruise ensures you see more of Doubtful Sound, and you can try activities like fishing or kayaking. There is time to relax and enjoy the scenery while keeping watch for wildlife such as penguins, dolphins, and seals. The smaller boat experience means we can get you up close to waterfalls and other points of interest. We would love you to join us and show you around these magnificent Fiords!
