About La Parguera Bioluminescent Bay Entry
This is the mouth of La Parguera's bioluminescent bay, one of only a handful of places in the world where dinoflagellates glow brightly enough to trace every paddle stroke. Unlike Mosquito Bay on Vieques, many tours here still allow swimming — and the glow is at its best on moonless nights.
