I did a day trip to St. Barths with my son who was 9 at the time. We had a great trip, it’s totally worthwhile. The morning that we left, the sea was a bit rough. The Captain, a Dutch woman with dreadlocks, refused to carry a pregnant woman and an elderly couple. But it was a fun ride and a great day in St. Barths. We went to the airport there to see the crazy landings (it’s another famous airport like SXM) and also to the incredible beach that begins just at the end of the runway. Gorgeous!!! We just used a taxi between both places easily- between the port and airport. It’s a beautiful place. Would totally return.
