La Parguera, on the southwest coast near Lajas, is the only one of Puerto Rico's three bioluminescent bays where swimming is generally allowed (see Bio Bay Without A Tour). Motorboats run here too, so you can glide out over the glow without paddling. Expect a bay historically dimmer than Vieques, yet still bright enough on good nights to trace light with every stroke of your hand.
