Since St Martin St Maarten is a Caribbean island you can forget the train for coming to visit us ! The only option is the plane and the boat to get to St Maarten.
But it’s still a lot of possibilities since St Maarten has 2 airports : Princess Juliana International Airport in Maho on the Dutch side and Grand Case Airport in Grand Case on the French side. The 2 St Maarten airports receive both commercial flights (from the US and other major regional and international airport) and private flights with private jet.
There is also St Maarten cruise port in Philipsburg. The St Maarten Port has been voted #1 for the Caribbean cruise and received nearly 2 millions passengers in 2016. Passengers who arrives through a cruise have the chance to visit St Martin island for a day and most of them visit Philipsburg St. Maarten for shopping and some of them take excursions tours.
In addition to that, St Maarten has plenty marinas for small boats and big yachts.
