Make your way to Oyster Bay or Marigot, depending on the day of your tour, check in at the ferry terminal with your passport in hand.
Board the 'Voyager 3', a climate-controlled catamaran-style ferry with a bar on board. The smooth ride across the sea takes approximately a half-hour from Oyster Bay or an hour from Marigot.
When you reach Gustavia, the capital of St Barts, board a minivan to transfer to your waiting Mini Cooper. Once you listen to a short safety briefing and orientation to the vehicle, you'll take off around the island. Stop by white-sand beaches, historical sites and lurxury villas owned by international celebrities and socialites.
After 2.5 hours, meet up in Gustavia for lunch at a local restaurant. Relax in the terrace dining room and dig in to a meal of French-influenced cuisine.
With a full belly, wander the streets of Gustavia for 2.5 hours of free time. Use the provided walking map of the town, check out the old fort, the Wall House Museum or the variety of galleries and boutiques. Alternatively, make your way to Shell Beach to swim or snorkel (snorkeling gear provided).
At the conclusion of your 9-hour day on St Barthelemy, take the ferry back to St Maarten.
