St-Barth’s only airport, Gustaf III, has the second-shortest runway in the world (the shortest is on Saba). Only teeny-tiny puddle jumpers can land on the island, and only during daylight hours. The majority of flights are to/from St-Martin/Sint Maarten's two airports but there are also less frequent and seasonal flights to/from regional destinations including Anguilla, Antigua, Guadeloupe, Puerto Rico, Saba and St Thomas. Airlines serving St-Barthélemy include Air Antilles Express, Air Caraïbes, St-Barth Commuter, Tradewind Aviation and Winair.
The €20 departure tax is included in all flight ticket prices.
No cruise ships dock at St-Barth, but a few anchor offshore and launch tenders to Gustavia's ferry terminal.
The ferry service between St-Barthélemy and St-Martin/Sint Maarten often hits choppy water so it’s a good idea to take motion-sickness medication beforehand. The €20 departure tax is included in most ferry ticket prices.
