Mosquito Bay on Vieques glows brighter than any other bio bay in Puerto Rico, and the only way in is with a DRNA-permitted operator. Six tours run here: kayaks, clear canoes, and quiet electric boats (see Electric Boat Tours). Swimming is prohibited to protect the dinoflagellates, so the glow stays intense. Every tour below has free cancellation.
