This surreal ghost town was originally built as a community for American oil workers who came to run the Lago Refinery in the 1950s. There were 700 residents, an English-language school, a social club, a beach club, a hospital, a local newspaper, and a bowling alley. Today, organ-pipe cacti form the backdrop for the sedate whitewashed cottages. Most people visit for the natural bridge. Keep bearing east past the
community, continuing uphill until you run out of road. You can then hike down to the cathedral-like formation. It's not too strenuous, but take care as you descend. Be sure to follow the white arrows painted on the rocks, as there are no other directional signs. The raw elemental power of the sea, which created this fascinating rock formation, complete with hissing blowholes, is stunning.
