Milford Sound is so beautiful. One of the best trips ever. By doing the cruise, under water observatory and the kayak we got to spend quite a bit of time and really got the full experience. Very friendly helpful informative guide. Anyone can do the kayak with the great launching platform that lifts and lowers you into and out of the water. Bonus great picnic lunch bag provided to each of us. The water is so crystal clear and you get to paddle right up to the sides of the fiords. Totally recommend whole experience is breathtaking from start to finish. Bonus of seeing dolphins and fur seals also.
