# Puerto Rico Sunset Magic: Bio Bay Kayaking Tour from Fajardo

**Guidekin's take:** A guided kayak into the bioluminescent lagoon at Fajardo led by marine biologists who explain what makes the water glow, with life jackets, whistles, back rests and snacks. Kayaks carry a strict weight limit per person, children ride from six, and the glow depends on the moon. 4.79 from 244 reviews at €63 per person.
