Bahamas
San Salvadore, the Bahamas. A dive heaven. dives from 30 foot fish dives to bottomless wall dives with large sharks and rare corals. Night dives are spectacular. There is not a lot of beach diving but the great diving is only minutes from the dock. This is the ideal "take classes in cold USA and open-water dives in paradise. Just great diving.
The Riding Rock Inn is a bit old but exceptionally comfortable. Great bar and restaurant. You must try their Bahama Mama, best drink in the Caribbean. Not a lot else to do on the island. I guided group trips here in the 70's and still in the 2010's it is a dive paradise. when on the east coast it is my go-to dive site.
