We took a morning trip in mid-July with Discovery Whale Watch and it was brilliant. Firstly we were really pleased to be allocated to their smaller boat as our children are 15 and 18 and this boat was pretty much just for adults. Our guide was very knowledgeable and was really keen to give us lots of information about what we were seeing. Then we were so lucky to see not one but two feeding frenzies, when a large number of whales, sea lions and dolphins all converge to feed together. It was an absolutely unforgettable experience. It was very cold on the water and even though we were warned about this, we perhaps didn't wear quite enough layers. Even so our numb fingers were quite forgotten at the sight of a humpback lunging out of the water mouth agape. At one point we were surrounded by sea lions leaping and barking. This was a really great trip and I would recommend Discovery for their policy of keeping numbers on the boats relatively small and the friendly professional crew.
