# 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. 4.85 from 362 reviews at €59 per person.

**Swim in the glow?:** Boat from La Parguera for a bio bay swim at €59 per person for 2h; own transport, bring towels. 4.85 from 362 reviews. Trade-off: Own transport; bring towels and snorkel gear. (last checked September 19, 2026)
