http://www.stmartinisland.org/st-martin-st-maarten-travel-information/useful-information.html On this website it does say that dogs are banned from beaches in St. Martin.Donna also said recently that she was stopped by the gendarmes on the beach with her dog last week and was reminded of this rule and that she would be fined if she did this again. It seems that they are going to enforce the rule now. She didn't say which section of the beach she was stopped on.
