Yikes! We never swam in PR. The water looked dirty everywhere. Then we took a puddle jumper to St. Croix where my cousin was living. He set us up with a day trip on a catamaran to Buck island for a day of snorkeling. Wow that was amazing.
The PR dive guides actively raped the seafloor of anything saleable while our friends were diving. Shells, conchs, you name it.
It was the opposite of “leave no trace”.
It was as if there was no law there.
