My daughter and I made a trip on July 27, 2013. This is our 5th whale watching trip, but previous were from Plymouth.
Dolphin Fleet has the cleanest ships (We traveled on Dolphin VIII). Every corner is washed and painted.
Trip was amazing. We never saw as many Whales, as this time. There are like 30 of them feeding and playing together. They were around the boat and it was so beautiful to see so many of these huge and peaceful animals at the same time.
One tip... Dress well, take something warm even on a hot summer day. It is chilly in the ocean. And don't forget sunscreen and camera!
