# Puerto Rico: Bio Bay Swim and Sunset Charter or Late night tour

**Guidekin's take:** 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.

**Swim in the glow?:** Boat from La Parguera, the one bay where you may swim, sunset sandbars then the glow, at €58 per person for 2h; towels not in. 4.84 from 361 reviews. Trade-off: Listing says little; towels and gear extra; long drive. (last checked September 19, 2026)
