I was asked on another thread what my favorite beaches are. So as to not hijack that thread, I said that I would start a new one in response to the question. My top favorite beaches, not necessarily in order, are:

Anse Marcel
Petite Plage (Grand Case Beach Club)
Grand Case Beach
Friar's Bay
Little Bay

All of these beaches generally have very gentle wave action, which is why I like them. I think that also may be true of Le Galion, but there's nothing there just now as far as amenities/services go.
