There are a few places to rent vehicles on Carriacou, with rates typically around US$50 per day. Quality Jeep Rental (443-8307; email@example.com; rental per day US$40), in L’Esterre, southwest of the airport, has good prices. There is a gas station on Patterson St in Hillsborough.
Buses (privately owned minivans) charge EC$2.50 to go anywhere on the island, or EC$1 if the distance is less than a mile. The two main routes run from Hillsborough – one south to Tyrrel Bay, the other north to Windward. Minibuses start at around 7am and stop at around sunset.
Some minibuses double as taxis, and usually you can count on a couple of them swinging by the airport when a flight comes in or by the pier when the boat arrives.
You can hire a taxi for a 2½-hour island tour, costing EC$150 for up to five people, or you can tour just the northern half, which takes half as long and costs EC$75.
