Above photo taken on Vieques Island looking back to Navio beach on the south coast with the entrance channel to the bioluminescent bay to the right. This group tour destination is no longer allowed by the DRNA. You could get to this beach, by swimming/snorkeling here from Navio on a calm day. ( Navio Beach in the background) Or renting your own kayak ( not easy to find).

Below is the same beach looking from a different angle, later in the day.
