Originally established as a community for oil workers, Seroe Colorado is also known for its intriguing 1939 chapel. Here, organ-pipe cacti form the backdrop for sedate whitewashed cottages. The best reason to come here is 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 watch your footing as you descend. Be sure to follow the white arrows painted on the rocks, as there are no other directional signs. Although this bridge isn't as spectacular as its more celebrated sibling (which collapsed in 2005), the raw elemental power of the sea that created it, replete with hissing blowholes, certainly is.
