Scuba, I have not been to Baja for years, but it is like no other place on the Planet, A land of contrast, stunningy beautiful, sparsley populated, a desert surrounded by ocean. Cabo Pulmo reef is now a National Park. The Church's guide is a good reference. Here is a Baja travelers forum, loaded with info.
