Will I get seasick on a Milford Sound cruise?

Will I Get Seasick
Short answer: most likely not. The fiord is sheltered by walls over a kilometre high and the water inside it is usually close to flat. The only part that moves is the mouth, where the fiord opens to the Tasman Sea, and most cruises go just far enough out to look back at the entrance. That leg is under about 30 minutes.

If you are prone to motion sickness

The rest of the trip runs 15 km along a sheltered fiord with rock on both sides, which is why people who avoid boats generally manage this one. The full run is described in what to expect on board.

Insider tip

If the sea state at the mouth worries you, book a cruise-only ticket and ask the crew at check-in what the bar is doing that morning. On a rough day some skippers turn short of the entrance anyway, and nobody on board minds.

The most comfortable boat for it

The modern catamaran has large windows and HD cameras projecting the outside view onto indoor screens, so you can sit still, stay warm and still see the cliff the boat is pointed at. It is also the cheapest ticket on the fiord and includes the car park fee. More options in cruise-only tickets.

Frequently asked questions

Is the Milford Sound cruise bumpy?

Rarely. Inside the fiord the water is usually close to flat because walls over 1,200 m block the wind. Only the mouth, where the fiord meets the Tasman Sea, moves at all, and boats spend under about 30 minutes there.

Do the boats go out into the open sea?

Not far. Most cruises run to the mouth of the fiord, go just far enough out to look back at the entrance and then turn. The total time in exposed water is short, as set out in how long the cruise takes.

Can I stay inside for the whole cruise?

Yes. Every boat has an indoor saloon, and the catamaran adds HD cameras projecting the outside view onto indoor screens. You will miss the spray at Stirling Falls, which is the part most people remember.
