Today we visited two islands in the center of the archipelago. On Bartholomew, we climbed a wooden staircase to the top of an old cinder cone for a chance to see the famous vista that captures many islands at once, in addition to Pinnacle Rock. In the afternoon, we navigated towards Sombrero Chino, where we had a great time snorkeling from Zodiacs and spotting wildlife. This is the home of a small colony of Galapagos penguins as well as Galapagos sea lions.
