It was a surprise bday gift - and an incredible one! We were originally sscheduled to cruise in the afternoon but bc it want sure to depart they reached out and we did the morning one instead. 1st of all, the Marlborough sound is absolutely stunning, and we had very calm water : it allowed us to see 2 of the endemic dolphins species present there : the dusky dolphins (they jumped out of the water for us!) and almost 10 Hector's dolphins they came very close, even swan under the boat! Those were fantastic encounters, + we got to see seals, blue penguins and a lot of very cool birds ! Very small boat with very few ppl, which made it all the more enjoyable. Overall fantastic experience, and shout out to Hanna and captain who shared all of their knowledge with us and we're very helpful.
