OPTION 1 FLY VIA ST MARTIN (SXM)
Specifically Princess Julianna Airport- airport (code SXM)
Depending on the city you will be flying from you can fly directly or with a connection to St Martin. Once in St Martin you will need to take a 15 minute connecting flight directly to St Barths! via WINAIR or ST BARTH COMMUTER
Please be mindful of the time in between your flight to St Martin and your connecting flight to St Barths. I would suggest at least 1 hour.
FERRY TRANSFER FROM ST MARTIN to ST BARTHS
There is also an option to take a ferry from St Martin to St Barths!
This can be a lovely more affordable option with beautiful sea views! Taxi or Shuttles provide transport from the airport to ferry docks.
You can book via GREAT BAY EXPRESS or VOYAGER These are both a bit of a drive from the airport so allow at least 2 hours in between landing and ferry departure. If you are prone to sea sickness I would not suggest this option :)
OPTION 2 FLY VIA SAN JUAN, PUERTO RICO (SJU) Depending on the city you will be flying from you can fly directly or with a connection to San Juan, PR. Once in San Juan you will need to take a 50 minute connecting flight directly to St Barths via TradeWinds Aviation
