St-Martin/Sint Maarten has plenty to offer younger travelers, with shallow beaches to splash about in the warm sea, water sports galore and family friendly attractions including the Butterfly Farm. Many resorts also have activity-packed kids' clubs.
Most accommodations can arrange cribs/cots by prior request. Especially on the French side, many restaurants have kids' menus but high-chairs are rare. Supermarkets stock baby-care items such as diapers/nappies.
