we will be at club orient wonder how is best way to day trip to st barts,,,,best day to do it to

daily commuter plane from Grand Case Airport.

the ferry out of Oyster Pond does multiple trips per day including returns after dark. the times we have seen it depart/return there have usually been quite a few passengers. Can be rough depending on seas.
Ticket office is steps away from DinghyDock bar, on the dock facing the harbor. Parking can be an issue that area. We usually take a right after the first gate heading toward Cptn Olivers, another quick right, past a row of apartmets to the right, and at end is parking that is usually open. Kind of isolated tho. Puts you above Quai Quest. Short walk to ferry ticket office from there. Otherwise lots of cars park along the street.
Don't forget passports and bring lots of $$
