Today our guests experienced Santiago Island. This is the Island that Darwin explored the most when he visited the Galapagos back in 1835. Darwin, together with some of the crew of HMS Beagle, camped on the island of Santiago for a week. While on the island, Darwin studied Galapagos marine and land iguanas, collected finches, mockingbirds, insects, and plants. Most of the species that Darwin collected were unique to the islands.
