We woke up anchored inside a caldera filled with seawater. Here we visited two destinations where about a million seabirds live and breed. We also snorkeled and kayaked inside the caldera, a unique opportunity in the Galapagos. We crossed the equator and celebrated the moment when the ship went from south to north. These two extraordinary events happened over the course of just one day. Sunset declared the day was over by painting the sky yellow and red. We declared an extraordinary day of expedition.
