Though this island hosts the second biggest population besides Santa Cruz, it's not often visited on cruises or by individual travelers. San Cristobol is charming and its capital, Puerto Baquerizo Moreno, is the capital of the islands. About 5,400 people live here, and many who do work for the government or in fisheries (the Galapagos' second largest income source). There is a bank and facilities for tourists, though is by no means close to Puerto Ayora's amenities. On San Cristobol, though, you may be lucky to see the red footed booby - the least seen of the bunch. It's also the home of the Chatham mockingbird, only found here on the island.
