This is our last full day in the magical Galapagos Archipelago, and early this morning National Geographic Endeavour II dropped anchor off the island of San Cristobal. Typically, the eastern and southern island have a higher rate of endemic species, among them the mockingbirds and the lava lizards. In the morning, we visited stunning Punta Pitt, with its tall, highly-eroded cliffs and gorgeous olive-green sands; this spot is inhabited by a colony of red-footed boobies, which unlike the other two booby species prefer to nest and rest on bushes and trees.

Our final excursion to the Galapagos natural areas took us to Cerro Brujo, further south in the island. San Cristobal was the first island to be explored by the cruise of HMS Beagle, and Charles Darwin himself landed on this beautiful, white sandy beach back in 1835. The fine drizzle and the warm sunrays of the afternoon produced a beautiful rainbow over the lava fields behind the beach: Such colors made the perfect grand finale to an incredible week in the Enchanted Isles.
