Planning to go to Milford Sound? Well why not take a moment to consider Doubtful Sound instead? Trips with Real Journeys depart from Queenstown daily and are a 13 hour round trip.
Fact alert! Captain James Cook discovered Doubtful Sound in 1770 and named it 'Doubtful Harbour' as he was unsure of whether he could sail into the inlet or not. It was later renamed as Doubtful Sound but it's actually a Fiord. Doubtful Sound is the second largest Fiord in Fiordland and the deepest at 421m.
