One of the highlights of the Alaskan cruise I took with my family was the whale watching tour in Juneau. Our boat was very uncrowded so everyone could get a good look at the same time. As we left Juneau we cruised for a while without seeing anything but birds.
We found three humpback whales, two adults and a calf, swimming together. The calf was swimming upside-down, waving its flippers around. I also saw the calf breach (leap out of the water and fall back in), but it was so random and fast that I couldn’t get a photo.
