A boat from La Parguera to the sandbars at sunset and then into the one bioluminescent bay in Puerto Rico you are allowed to swim in, floaties provided. The listing says little beyond that: towels and snorkel gear are not included and there is no transport from San Juan. 4.84 from 361 reviews at €58 per person.
You will visit two very unique places the sandbars of La Parguera and one of the five Biobays in the world and the only one you can swim in. Very nice boats and skillful Captain.
