Los Islotes, sea stacks formed 20 million years ago, were the site of our afternoon explorations. The Sea Lion was at anchor close enough to shore to view some of the blue-footed boobies, brown boobies, and magnificent frigate birds that inhabit the rocky ledges. Some of our guests remained on the ship to view the seabirds as well as the California sea lions that were either resting on the rocks or frolicking in the water. Many of us also went snorkeling and what a thrill it was to put our faces into the 'refreshingly' cool waters of the Gulf of California to view the colorful and diverse rocky reef fish, while the sea lions gracefully glided and twirled around us. These two guests are looking at an incredible undersea world that one can only imagine.
