One lovely island in the Caribbean Sea is composed of a Dutch southern side called St. Maarten and a French northern side called St. Martin. St. Maarten is known for its shop-lined, narrow lanes and daytime casinos. Enjoy snorkeling in Philipsburg, golfing at Mullet Bay or parasailing on Orient Beach. Hiking, horseback-riding and fishing top off a long list of activities available to St. Maarten's visitors.
