Argyle International Airport opened in February 2017 on the eastern coast six kilometers from Georgetown, ending decades in which Saint Vincent had no jet-capable runway. The airport accepts regional turboprops and narrow-body jets on its 2,700-meter runway. Most North American passengers connect through Barbados, Saint Lucia, or Grenada on Caribbean Airlines, LIAT (when operational, though the carrier suspended most routes in 2020), or charter services. Direct flights from Toronto operate seasonally on Air Canada Rouge. Visitors arriving from most Commonwealth countries, the United States, Canada, and the European Union receive entry permission for up to thirty days without advance visa application. The standard entry stamp allows one month, with extensions available through the Immigration Department in Kingstown for documented onward travel. Travelers must present proof of accommodation, return tickets, and demonstrate financial means during the stay, though exact dollar thresholds are not published in immigration regulations.
The Eastern Caribbean dollar circulates across eight island nations at a fixed rate of 2.70 EC dollars to one US dollar, a peg maintained since 1976. United States dollars are accepted in hotels and tour operators but generate inconsistent exchange rates and often round unfavorably. The Eastern Caribbean Central Bank, headquartered in Saint Lucia, maintains this currency union. Most ATMs on Saint Vincent dispense Eastern Caribbean dollars exclusively, not US currency. First Caribbean International Bank and Bank of Saint Vincent and the Grenadines operate the majority of machines, concentrated in Kingstown with single units in Georgetown and Barrouallie. These machines accept Visa and Mastercard networks, apply international withdrawal fees set by issuing banks, and often limit single transactions to 500 EC dollars. Credit cards work at larger hotels and car rental agencies in Kingstown but are refused at guesthouses, most restaurants outside the capital, and all minibus transport.
Banking hours run Monday through Thursday from 8:00 to 14:00, Friday from 8:00 to 16:00. First Caribbean International Bank on Halifax Street in Kingstown exchanges major currencies including US dollars, Canadian dollars, British pounds, and euros. Bank of Saint Vincent and the Grenadines performs the same function at its branches in Kingstown, Georgetown, and Barrouallie. The Bank of Saint Vincent location on South River Road in Kingstown operates a dedicated foreign exchange counter separate from retail banking queues. No private foreign exchange bureaus operate on the island. The airport terminal contains no currency exchange service, ATM access, or banking facility as of mid-2024, an omission noted by arriving passengers who find themselves with foreign cash and no conversion option until reaching Kingstown.
Cash remains the primary transaction medium outside Kingstown. Minibuses running the established routes between Kingstown and Georgetown, or Kingstown to the Leeward Highway towns, operate on cash fares collected during transit. Roadside vendors selling produce in the Mesopotamia Valley accept only Eastern Caribbean currency. The Kingstown Market on Bay Street, operating since the late 1800s and still the central wholesale point for vegetables and fish, functions exclusively in cash transactions. Water taxis departing from the Kingstown waterfront for short coastal trips to Villa Beach or Calliaqua quote prices in EC dollars and do not carry card terminals. Even Fort Charlotte, maintained by the National Parks authority, collects its small entry fee in physical currency from a staff member at the gate.
Saint Vincent switched its electrical standard from 110 volts to 230 volts at 50 hertz in the early 1990s, aligning with most Caribbean nations. Outlets accept British-style three-prong rectangular plugs, type G in international nomenclature. North American devices require both voltage converters for non-dual-voltage electronics and physical plug adapters. Laptops and phone chargers typically handle 100-240 volts automatically, requiring only the physical adapter, but hair dryers, curling irons, and other heating appliances from the United States will burn out without a step-down transformer. Hotels sometimes provide adapters at front desks, but availability varies by property size. Hardware stores in Kingstown on Halifax Street and Bay Street stock plug adapters for 15-25 EC dollars.
Tap water comes from mountain catchments, rivers including the Colonarie, and treated reservoirs managed by the Central Water and Sewage Authority. Kingstown and larger coastal settlements receive chlorinated municipal water meeting World Health Organization guidelines for pathogen reduction. The water authority publishes annual quality reports documenting coliform counts and chemical composition. Most hotels and guesthouses serve this municipal water for drinking without additional filtration. Rainfall provides significant watershed volume, with annual precipitation exceeding 3,800 millimeters in the mountains near La Soufrière. Rural areas in the interior and some coastal villages rely on untreated spring sources or rainwater collection systems, where filtration or boiling eliminates biological risk. Bottled water from regional brands including Hairoun and Island Water sells in shops for 3-5 EC dollars per liter.
Mobile service operates through two providers: Flow, owned by Cable and Wireless, and Digicel. Both companies maintain 4G LTE networks covering Kingstown, the Leeward and Windward Highway coastal routes, and Georgetown. Coverage diminishes in the mountainous interior around the Vermont Nature Trail and disappears entirely above 600 meters elevation near La Soufrière's hiking trails.
