With 12,000 residents, the town of Puerto Ayora has about half of the population of the Galápagos Islands. This quaint seaport is located at the south end of Santa Cruz Island, the second largest in the UNESCO World Heritage Site archipelago. The town’s namesake is Isidro Ayora, an Ecuadorian president from 1926 until 1931. All cruise ships and island tour passengers arrive for a dry landing at this municipal pier.
