We took the 3 hour whale watching tour. The whether is great and the sea surface is calm. So we can see the whale bust from far distance, this helps us finding the whales. We saw 8 different gray whales, and one group of 3 gray whales, it's really fun to see 3 whales travelling together. We are also lucky to see a group of dolphins too. this is really a fun activity, would definitely do this again if we come back to San Diego again. We book the tour through Groupon, and it really offers great deal.
