Trying the different beaches and restaurants are part of the St Barths experience, so wherever you stay on the island you will need a car. Though St Barths is quite small. From anywhere on the island, you can get to any other part in less than 20 minute drive. Any valid driver's license will do, and for those used to smooth, wide and level roads, the business of driving on St. Barths can be an aventure in itself.
There are two gas stations on the island, both closed on Sunday. The one near the airport is open Monday through Saturday from 7:30 a.m. to noon and 2 to 7 p.m. The one in Lorient is open from 7:30 a.m. to 5 p.m., except on Thursday and Saturday afternoons. There is an all-night automatic credit card gas pump at the airport station (it does not always work with foreign credit cards). 
There are two taxi stations on the island, one at the airport and one in Gustavia on the public dock.
