Like so many of the islands in the Galapagos, San Cristobal is formed by dormant volcanoes. It lies to the east of the archipelago and is one of the oldest islands in the group. Approximately 6,000 people live on the island, making their living from tourism, fishing, in government offices, or off the rich volcanic soils with some limited farming existing in the highlands. Puerto Baquerizo Moreno on the southwestern tip of the island is the capital city of the Galapagos Islands. A statue of Charles Darwin graces the harbor, marking one of the first places he likely stepped ashore in the 1830s.
