The Island of San Cristobal or Chatham is one of only four inhabited islands of the Galapagos archipelago. It is home to the town of Puerto Baquerizo Moreno which is the capital of the Galapagos province and the political center of the islands. The airport of San Cristobal is one of only two airports that connect the Enchanted Islands with the mainland. San Cristobal Island is not as commercial as Santa Cruz because of its location in the far east of the archipelago but it is still the starting point of many cruises and tours.
