Minibuses are the cheapest and most characterful way to get around Grenada. They run fixed routes from the Esplanade bus terminal at the west end of Granby Street in St. George's, heading out to all main points on the island. Fares are low — St. George's to Grand Anse is EC$2.50. Buses run frequently during the day but most stop around 7pm, and Sunday service is minimal. Flag one down from the roadside; to get off, shout "drop one."
Taxis are plentiful and fares are set by the government, though you should confirm the price before you get in. A taxi from St. George's to Grand Anse Beach is EC$35–45. Members of the Grenada Taxi Association have received additional training and are generally a reliable choice. Taxis can also be hired by the hour for island tours; it is worth asking around for a driver who is also a good guide.
Water taxis run between St. George's and Grand Anse Beach along the southwest coast. They are faster and more pleasant than road traffic for this stretch, and cost around EC$10 each way.
Car rental makes the most sense if you want to explore the interior and north of the island at your own pace. You will need a valid driving licence and a local permit, available from rental agencies or the Central Police Station in St. George's for EC$30 (about US$11). Driving is on the left. Roads in the interior are narrow and winding. Several local agencies and international companies operate at the airport and in Grand Anse.
Getting to Carriacou: Osprey Lines ferries depart the Carenage daily (around 2 hours, EC$80). Grenadine Air Alliance and SVG Air offer short flights from Maurice Bishop International Airport; the flight takes under 30 minutes and costs considerably more than the ferry. Minibuses on Carriacou connect Hillsborough with Windward and Tyrrel Bay.
