We began our day by hiking to the top of a tuff cone known as the Islet of Bartolome, where we were transported back to a time when the land was newly formed. The walk allowed us to understand the formation of the islands and the volcanism of the Galapagos. Later, we enjoyed the wonders of the ocean. In the evening, we went to Chinese Hat Islet to snorkel from the Zodiacs. The area is home to a small colony of Galapagos penguins. In a sandy-bottomed, sheltered channel, our guests enjoyed swimming with whitetip reef sharks, rays, and many colorful schools of fish.
