I spent a week in Puerto Rico many years ago. Traveled all over, but don’t recall these caves. Island was beautiful and safe then, people charming.
But now, if you take a Caribbean cruise, you’re advised to NOT go ashore in PR because it’s so dangerous.
A travel agent told me I could spend six nights in Puerto Rico. No days, just nights. I said to him, ‘What will I do with myself days?’ He said, ‘Do whatever you want, just keep out of Puerto Rico.’” - Rodney Dangerfield
