On my December 2013 trip to Baja California Sur, my wife and I took a day trip to Todos Santos. Once there, I had hoped to see the Antiguo Panteon, or Old Cemetery. It was a few blocks walk from the bus station, and was worth a few minutes to look around.
Here’s a link to a Google Map with the Cemetery noted, should you have trouble finding it. I hope you enjoy the the photos. Please click them to see larger versions.
