Every significant airport in the world has an official identifier, like AUS for Austin Bergstrom and DFW for Dallas-Ft. Worth. The official identifier for the primary airport in the Galapagos Islands is GPS (GalaPagoS).
The GPS airport is powered by three wind turbines, making it carbon neutral.
GPS is located on Baltra Island, which it shares with a military facility. Most visitors to the Galapagos Islands fly from Quito or Guayaquil to GPS, then take a bus to a dock, ride a small ferry to a similar dock on Santa Cruz Island. Upon arrival on Santa Cruz Island they catch one of the waiting taxis for the 40-minute ride to Puerto Ayora, the largest town in the Galapagos Islands.
Here are some photos I took recently of the GPS airport, the ferry and the drive to Puerto Ayora.
