Union Island Travel Guide

Union Island is the southernmost inhabited island of Saint Vincent and the Grenadines, sitting close to the maritime border with Grenada. At roughly 8 square kilometres, it is small but punches above its weight as a hub for sailors, kiteboarders, and travellers looking for an unhurried corner of the Eastern Caribbean.

The main settlement, Clifton, functions as the island's commercial and transport centre. Its small harbour is a recognised port of entry for yachts, and the compact waterfront has a handful of restaurants, provisions stores, and a fish market. The smaller village of Ashton lies to the southwest and serves as the main access point for kite beach.

Union Island's landscape is dominated by Mount Taboi and Mount Parnassus, giving it a slightly more rugged profile than the flat coral cays nearby. Mangrove lagoons, reef-sheltered anchorages, and the wide, wind-swept flats near Ashton make it ecologically varied for its size.

Because it sits at the southern end of the Grenadines chain, Union Island is a natural staging point for day trips to the Tobago Cays, Mayreau, Palm Island, and Petite St. Vincent — making it as much a base as a destination in its own right.

Visas and Entry

Saint Vincent and the Grenadines has its own entry requirements. For current visa rules specific to your nationality, check TravelerPulse's Visas section and the official SVG Immigration Authority website before travel.

Health

No mandatory vaccinations are required for most travellers arriving from non-endemic countries, but recommendations change — consult your GP or a travel health clinic before departure. The island has limited medical facilities; serious conditions require evacuation to St. Vincent (mainland) or Barbados. Travel insurance that includes medical evacuation is strongly advised.

What to Pack

• Light, breathable clothing; a rain layer for brief tropical showers
• High-SPF reef-safe sunscreen
• Insect repellent (mosquitoes are present, especially near mangroves)
• Cash in XCD or USD — card acceptance is limited outside Clifton
• Any prescription medication you need, as pharmacy stock is limited

Money

ATM availability on Union Island is limited and machines can run out of cash or be out of service. Bring sufficient cash from a larger island or the mainland. Verify ATM locations locally on arrival.

By Air

Union Island has its own small airstrip, J.F. Mitchell Airport (UNI), which handles inter-island propeller aircraft. Scheduled and charter services connect it primarily to E.T. Joshua Airport (or the newer Argyle International Airport) on St. Vincent's mainland, as well as to Canouan, Mustique, and occasionally Barbados. Airline schedules and operators serving this route change seasonally — verify current options directly with carriers or through a local travel agent.

By Ferry

Regular ferry services run through the Grenadines, connecting Union Island to Bequia, Canouan, Mayreau, and the St. Vincent mainland. The Admirable Bay ferry terminal in Clifton is the main point of arrival. Schedules are subject to weather and seasonal changes; confirm departure times locally or with the ferry operator before your trip.

By Yacht

Clifton Harbour is an official port of entry for private yachts. Customs and immigration clearance can be completed here. The anchorage is sheltered and well-established on the Caribbean sailing circuit, particularly popular between December and April.

Union Island is small enough that most areas of Clifton are walkable. The road between Clifton and Ashton can be walked in under an hour, though the heat and hills make it tiring in the middle of the day.

Minibuses and shared taxis operate between the main villages. Agree on the fare before setting off — there are no meters. Water taxis are available for reaching nearby cays and are commonly arranged through your accommodation or at the Clifton waterfront.

Renting a vehicle is possible but options are limited; inquire locally on arrival. For many visitors, a combination of walking, shared transport, and water taxis covers every practical need.

Accommodation on Union Island is limited in scale and variety, which is part of its appeal. Options range from small guesthouses and locally run inns in and around Clifton to a handful of more comfortable properties. Palm Island (a private island resort accessible by water taxi) and Petite St. Vincent are nearby alternatives for travellers seeking higher-end resort experiences.

Sailors frequently stay aboard their vessels in Clifton Harbour or at Chatham Bay anchorage. Mooring buoys are available in some areas — confirm availability and any fees with the local port authority.

Booking ahead is advisable for the December–April high season, when both accommodation and berths fill up quickly. For specific property names and current rates, check a reputable booking platform or contact the SVG Tourism Authority for an up-to-date list.

Kitesurfing and Windsurfing

Union Island — and specifically the area around Ashton and the southern lagoon — is widely regarded as one of the Caribbean's best kitesurfing destinations. The trade winds are reliable from December through April, and the shallow, protected waters near the lagoon are well-suited to beginners and intermediates. Several kite schools and rental operators are based here; verify current operators locally.

Chatham Bay

On the western, leeward side of the island, Chatham Bay is a broad, largely undeveloped anchorage backed by hills. It is accessible by water taxi from Clifton and is a popular stop for sailors and day visitors seeking a quiet beach. Facilities are minimal — a small number of beach bar operations exist, but verify what is currently open before making the trip.

Hiking

Mount Taboi (the island's highest point at roughly 305 metres) offers a hike with views across the southern Grenadines. Trails are not heavily maintained; a local guide is advisable. Ask at your accommodation for current trail conditions and guide recommendations.

Day Trips

Union Island's location makes it an ideal base for exploring the southern Grenadines. The Tobago Cays Marine Park — a protected snorkelling and diving area — is reachable by boat and is considered one of the finest reef systems in the Eastern Caribbean. Mayreau, Palm Island, and Petite St. Vincent are all within a short boat ride.

Snorkelling and Diving

Local reefs around Union Island support coral and marine life typical of the southern Grenadines. Dive operators based in Clifton can arrange guided dives; verify current operators and pricing on arrival.

Clifton's waterfront has the greatest concentration of eating and drinking options. Expect a mix of small local restaurants, fish fry setups, and simple bars catering to the sailing crowd. Fresh fish and lobster (in season) are commonly available and generally straightforward to find near the harbour.

Local Vincentian cooking features provisions (root vegetables such as dasheen and breadfruit), rice and peas, grilled or stewed fish, and chicken. Rotis are a practical, inexpensive snack widely available across SVG.

Beer (notably Hairoun, the local SVG lager) and rum-based drinks are standard at most bars. Provisioning stores in Clifton stock basics for those on charter yachts or self-catering.

Restaurant turnover on small islands can be high. Specific establishment recommendations are best sought from your accommodation or fellow travellers on arrival, as what is open and well-regarded changes from season to season.

Communications

Mobile coverage exists on Union Island but can be patchy depending on your carrier and location. Local SIM cards from Digicel or Flow (the main regional carriers) are available and generally offer better coverage than roaming. Wi-Fi is available at some accommodation properties and restaurants but should not be relied upon for work purposes.

Electricity

SVG uses 110V/60Hz with North American-style flat-pin plugs, though some properties may also accommodate UK-style plugs. Verify with your accommodation and bring a universal adapter to be safe.

Emergency Contacts

For emergencies in SVG, the general emergency number is 911. The nearest hospital with meaningful capacity is on the mainland of St. Vincent; serious medical situations will require evacuation. Confirm current local clinic hours on arrival.

Opening Hours

Business hours are informal by international standards. Many shops in Clifton close on Sundays and public holidays. Do not assume services will be available outside of weekday morning hours without confirming in advance.

Union Island is generally considered safe for travellers, with low levels of violent crime compared to many Caribbean destinations. The usual common-sense precautions apply: avoid displaying expensive jewellery or electronics conspicuously, don't leave valuables unattended on beaches, and be aware of your surroundings at night in unfamiliar areas.

Water safety is worth attention: ocean conditions can change quickly, currents around headlands can be strong, and some beaches have no lifeguards. If you are kitesurfing or engaging in any watersport, use a reputable operator with proper safety briefings and equipment.

Union Island, like the rest of SVG, has a culture rooted in Afro-Caribbean heritage, with influences from the island's colonial history and the presence of the indigenous Garifuna people on the mainland. The pace of life is unhurried, and patience is appreciated — things often move more slowly than travellers from larger cities may expect, and this is considered normal rather than a failing.

The island hosts the Union Island Festival (sometimes called 'Big Drum' or associated with the broader Easterval celebrations in SVG), typically held around Easter. Dates and programming vary — verify locally if you are planning your trip around it.

Dress modestly when away from the beach; swimwear is appropriate on the shore but not in village streets, shops, or churches. Greetings matter — a brief 'good morning' or 'good afternoon' before launching into a request is standard courtesy and appreciated.
