US Virgin Islands (St Thomas) the diving here is much better than San Juan. The Dive company took us to a reef called Sprats Reef, viz was around 20m and the temperature varied from 27 to 28° no Sharks but did find a turtle.
2nd Dive was on the wrecks of a couple of old Navy Barges. A lot of fish life around these wrecks.
