We booked to celebrate my parents 50th anniversary ... they visited me from Canada. It was a very special celebration and they enjoyed every moment of the cruise as part of their South Island experience. I've been to Milford during Summer and recently during Winter to tour my family. Milford Sound will always be a breathtaking view!

The beautiful scenery coupled with the good commentary from the captain is worth the trip to Milford Sound. We were also amazed by the wild life conservation effort undertaken at the area
Breathtaking Milford sound

Milford Sound is one of the most breathtaking locations on Earth and it's worth spending a few days exploring it. Is it on your New Zealand bucket list?

Jorja_G, Jun 2023
the most memorials part of my experience was the waterfalls, seeing dolphins and the amount of information shared at the observatory
A wonderful cruise
Sahika_J, Jun 2023
Extremely happy with this cruise. It was informative, the captain made time to stop and point out things of interest including twice showing us some deals, and the underwater observatory was fantastic! Food provided was fresh and plentiful. We had a fabulous time, thank you!

The stunning scenery and beautiful weather on the day. The underwater observatory was an added bonus & the staff there were very informative.
The worst Experience
Vinay_U, Jun 2023
I booked the cruise for 4th of June at 10 am. Me and my girlfriend planned the Queenstown trip for 3 nights and 2 days. On 3rd June, we left Christchurch in the morning and reached Queenstown around 7 pm. I received a message from the tour operator notifying me about Milford Sound road closure till 10 am the next day due to snowfall and assured a cruise later that day for those whose can make it. As I was driving, I didn't notice it until we reached Queenstown. We planned 2 days perfectly for the trip. On the 4th we booked an early cruise for 10 am and after that at 6:30pm we made reservations for dinner with our common friends as it was my girlfriend's birthday. On the second days we booked the shotover jet, onsen hot pools and ice skating and the rest of the time for shopping. Just when I noticed the email, I contacted the tour operator stating that we cannot make it to a later cruise. A total 8 hours drive back and fourth from Queenstown to Milford Sound and 2 hour cruise, we cannot make it back in time to our reservation if we leave Queenstown for the cruise at 10 am. I contacted the tour operator about this and they said they cannot process a refund. I understood the situation and kindly asked for voucher for us, that we can use later as it's not our fault. They asked me to contact viator about this and I did. At first the customer care told that they would do a refund. Then the next day they send me an email saying they cannot process a refund and to which I replied if they could give me a voucher. Within minutes, I received the email from another customer care executive saying after careful valuation, they cannot do the refund or issue a voucher for the same. I was charged 258 dollars for a service that I didn't receive and it's not our fault. The worst experience that I ever experienced.

Breathtaking views and the underwater discovery was a great bonus! Great staff and the captain did a terrific job narrating and giving us some up close encounters.
A very worthwhile experience
Merelyn_C, May 2023
Milford Sound is amazing and having the opportunity to explore by boat was so worthwhile. Seeing the seals, dolphins and bird life topped off the waterfalls and the mouth of the Sound to the Tasman Sea. The observatory was interesting and helped fill in the picture of the area. The picnic boxes were a great idea. We drove in by car and that also formed part of the wonder of the experience.

It was great! The large boat where you can walk and look around. Free tea and coffee. Nice and really big lunch included. And also underwater observatory was awesome.
Fantastic experience!!
KekLian_P, Apr 2023
We had a beautiful day when we did the cruise so it made it. One grumble is that we could not hear the commentary very well. Lunch that was served was excellent and plentiful.
Jo_L, Apr 2023
Really nice, lovely picnic lunch. The waterfalls and the fiord itself are spectacular. Dolphins and seals along the way. The underwater observatory was a little lack lustre, very poor visibility and hardly any fish. It’s a long drive from Queenstown and back so be prepared for a full 12-13 hour day.
Great way to see the fyord.
Beth_M, Apr 2023
How close the captain got to everything. Also the underwater experience in the observatory. Stunning scenery.
