This specific plan is valid only within Martinique. Many travelers take the L'Express des Îles ferry to visit neighboring islands like St. Lucia, Dominica, or Guadeloupe. Be careful: St. Lucia and Dominica are independent nations, not part of France. Once you cross the maritime border, your connection will stop. For island hopping, we highly recommend our Caribbean Regional eSIM to stay connected everywhere.
