At 11 AM, we went snorkeling at Devil's Crown, know to be one of the best places to snorkel in the Galapagos Islands. Called the Devil's crown because it looks like a crown jutting out of the water, it is a volcanic crater in the water off the the island of Floreana. We started on the outside of the crown, where the current is quite strong. Hundreds and hundreds of fish were there, some deeper than others. The water gets deep fairly quick as you move away from the crown. At times I saw down about 15 feet amongst the schools of colorful tropical fish. We swan with the current and then swam around so that we we inside the crown (crater). The water was shallower inside, but the current still strong. We saw several interesting starfish and large schools of sardines. Then I saw a good-sized shark. When I turned around again to try to take a photo, it was gone, nowhere to be found. There are also a few sea lions swimming around as well. Overall it was the best snorkeling we had seen in Galapagos (so far).
