On our fourth day on board the National Geographic Endeavour II, we stopped by the south side of Santa Cruz Island. The archipelago’s second largest island is almost 1000m2 in area and circular in shape. Located in the center of the Galapagos, it is also the economic center and has the highest population of the five inhabited islands. Today, we had the chance to explore Puerto Ayora, a town of about 12,000 residents. At the Galapagos National Park giant tortoise breeding center, we learned about the efforts to save these endangered animals and saw a variety of species in corrals. We then traveled to the highlands to see giant tortoises in the wild. Along the way, we stopped at a local farm stand to sample products made from sugar cane, coffee, and cacao. We concluded our busy day visiting local artisans.
