The Maori’s will tell you that Doubtful Sound was created by Tu Te Raki whanoa and today you can feel the impact of that mystery when the weather changes from brilliant blue skies to a misted landscape in literally minutes.
The best way to appreciate Doubtful Sound is to take one of the many small boat cruises available, or go for an overnight cruise. That will give you a chance to appreciate the Browne Falls that flow over 2740ft into the fiord. Or look for dolphins in the Deep Cove.
If you are doing a South Island trip then you can take a return one day trip from Manapouri to Doubtful sound on one of many modern launches. The trip leaves from Pearl Harbour in Manapouri itself (20 minutes drive from Te Anau).
