Grenada maintains 1,127 kilometers of roads, of which 687 kilometers are paved. The main highway circles the perimeter of the island connecting St. George's to Grenville, Sauteurs, and Gouyave, covering approximately 100 kilometers. Interior roads climb through the mountainous central region via narrow routes that access Grand Etang National Park and connect eastern and western coasts. Road conditions vary significantly, with coastal highways generally well-maintained while mountain roads feature potholes, limited shoulders, and steep gradients. Hurricane damage periodically closes or degrades secondary routes.
Driving occurs on the left side. Foreign visitors require either a valid international driving permit or a temporary Grenadian license obtained for 30 Eastern Caribbean dollars upon presentation of a home country license at police headquarters in St. George's or at car rental locations. Rental agencies require drivers to be at least 21 years old, with some companies setting minimums at 25. Daily rental rates start at 150 Eastern Caribbean dollars for manual transmission compact vehicles and reach 400 Eastern Caribbean dollars for automatic SUVs. Insurance adds 40 to 60 Eastern Caribbean dollars daily. The condition of rental vehicles varies widely between operators. No vehicle rental services operate on Petite Martinique.
Local minibuses provide the primary public transportation system. These privately owned vehicles operate without fixed schedules, departing when full, typically holding 12 to 15 passengers. Routes radiate from St. George's to all major towns, with the longest run to Sauteurs taking approximately 90 minutes and costing 12 Eastern Caribbean dollars. Bus stops lack signage but occur at established locations known to residents. Buses display route numbers in windshields: number one serves Grand Anse, number two runs to Grand Mal, number four goes to Grenville. Service frequency drops after 6 PM and becomes sparse on Sundays. Carriacou operates a similar system centered on Hillsborough with fares of 5 to 8 Eastern Caribbean dollars island-wide.
Taxis lack meters. Drivers charge fixed rates based on zones, with costs from Maurice Bishop International Airport to St. George's at 35 Eastern Caribbean dollars, to Grand Anse at 25 Eastern Caribbean dollars, and to Lance aux Epines at 30 Eastern Caribbean dollars. Island tours by taxi run 300 to 500 Eastern Caribbean dollars for four hours depending on route and passenger count. Water taxis operate from the Carenage in St. George's to Grand Anse Beach for 8 Eastern Caribbean dollars per person. Taxi availability concentrates in St. George's and tourist areas but remains limited in rural locations after dark.
The Osprey Lines ferry connects Grenada to Carriacou and Petite Martinique, departing from the Carenage in St. George's. Service runs Monday through Saturday with one daily sailing in each direction, departing St. George's at 9 AM and returning from Carriacou at 5:30 PM. The passage to Hillsborough takes three hours in typical conditions and costs 80 Eastern Caribbean dollars one-way economy class, 140 Eastern Caribbean dollars business class. Seas in the channel between Grenada and Carriacou frequently produce rough conditions causing delays and cancellations, particularly from December through March. Advance booking proves essential during Carriacou Carnival in February and the August Spicemas period. The ferry carries vehicles at 400 Eastern Caribbean dollars one-way for standard cars.
Inter-island air service operates through SVG Air, which flies between Maurice Bishop International Airport and Lauriston Airport on Carriacou. Flights depart multiple times daily, with schedules varying by season from three to six round trips. Flight time is 20 minutes. One-way fares range from 200 to 280 Eastern Caribbean dollars. Lauriston Airport accommodates only small aircraft and lacks jet service. Weight restrictions limit luggage to 15 kilograms per passenger on some flights.
Walking remains the practical method for navigating St. George's compact downtown centered on the Carenage, with the distance from the harbor to Fort George covering less than one kilometer. The town's steep hillside layout means most routes involve sustained inclines. Grand Anse Beach stretches three kilometers with pedestrian access along its length, but the connecting main road lacks continuous sidewalks. Villages outside major towns provide limited pedestrian infrastructure. Heat and humidity make midday walking strenuous, with temperatures regularly reaching 30 to 32 degrees Celsius.
Boat charters access offshore islands and remote beaches. Water taxis to Hog Island from Grand Anse cost 25 Eastern Caribbean dollars round trip. Private boat charters for snorkeling or diving excursions start at 350 Eastern Caribbean dollars for half-day trips with higher rates for full-day voyages to the Grenadines. Sailing charters and yacht rentals operate from Port Louis Marina and Prickly Bay Marina, with bareboat weekly rates beginning at 5,000 US dollars for monohulls in low season. The Molinere Underwater Sculpture Park requires boat access, with operators charging 120 to 200 Eastern Caribbean dollars including equipment.
