Cruise to Doubtful Sound, New Zealand

Situated in Fiordland National Park, Doubtful Sound is the deepest and second-largest fjord in New Zealand. It was named by Captain Cook, the first European here, because he was doubtful that he would be able to sail his ship, the Endeavor, back out of the sound due to the westerly winds. Look for the area's towering waterfalls: See 619-meter Browne Falls in Hall Arm and 220-meter Helena Falls at Deep Cove. Try to spot dolphins, penguins and fur seals in the waters and shoreline below with your Doubtful Sound cruise.

The Sound of Silence

Doubtful Sound is very remote. The closet towns are on nearby lakes Te Anau and Manapouri, and most visitors to the area come in aboard ships. Take in the vastness of the scenery and the quiet of the fjord.

Wave to Wildlife

Pods of dolphins cruise through Doubtful Sound, along with the occasional whale. Fur seals, penguins and several varieties of birds such as puffins also call this area home. Watch for splashes in the water and puffs of mist, which show where the cetaceans have surfaced and taken a breath.

Watch for Waterfalls

Thanks to the more than 200 days of rainfall every year in Fiordland National Park, Doubtful Sound has plenty of waterfalls to admire. You might even see a rainbow when the sun comes out during your Doubtful Sound cruise. Helena Falls in Deep Cove is particularly spectacular after a heavy rain.
