We left Ponce, but not until almost 0800, as we were just going 7 miles offshore to an island called Caja de Muertos, literally Box of the Dead or Coffin Island. Supposedly, the island looks like a man laid out ready for burial, hands clasped on his chest. I didn't see it, I guess maybe if you squinted. Anyway, the island is a park, run by the DNR and they have these great boats that say "Vigilantes" down the side. I know that in the US the term vigilante has a bad connotation but here is just means watchman or caretaker. We went on blistering hot hike up the hill to the old lighthouse, the views of the island and of Puerto Rico in the distance were spectacular.
