For a more leisurely and scenic approach, taking a ferry from St Vincent to Union Island is an unforgettable experience. This option allows you to immerse yourself in the natural beauty of the Grenadines, feeling the ocean breeze and witnessing the islands gradually appear on the horizon.

The MV Barracuda: A Reliable Choice

The primary passenger and cargo ferry connecting St Vincent to the southern Grenadines, including Union Island, is typically the MV Barracuda. This vessel offers a vital link for both locals and tourists, providing a practical and often more economical alternative to flying.

  • Departure Point:Ferries depart from the main port in Kingstown, St Vincent.
  • Schedule:The MV Barracuda usually operates a few times a week, though schedules can vary and are subject to change. It's crucial to verify the latest timetable closer to your travel date.
  • Journey Time:The sea journey is considerably longer than flying, often taking several hours, including stops at various islands along the way.

  • Onboard Experience:Expect a relatively comfortable journey, often with both indoor and outdoor seating options. You'll share the experience with locals and other travelers, making it a unique cultural immersion.

Other Ferry Services and Private Charters

While the MV Barracuda is the most common public option, there might be other less frequent inter-island ferries or cargo boats that occasionally take passengers. For greater flexibility, particularly for groups or those with specific timings, private water taxis or charter boats are also available. These can be arranged from St Vincent or through tour operators and offer a more direct and personalized journey, though at a higher cost.

Planning Your Trip: Essential Tips

Regardless of whether you choose to fly or take the ferry, a little planning will ensure your journey from St Vincent to Union Island is smooth and stress-free.

Booking in Advance

For both flights and ferries, securing your tickets in advance is highly recommended. This is especially true during peak tourist seasons (typically December to April) and around major holidays. Ferry tickets can often be purchased on the day of travel at the port, but pre-booking or arriving early is wise to guarantee a spot.

Luggage Allowances

As mentioned, flights on smaller aircraft have strict baggage limits. Ferries, while generally more lenient, still require passengers to manage their own luggage. If you're traveling with oversized items (like kitesurfing gear, popular on Union Island), contact your chosen transport provider beforehand to confirm their policies and any potential additional fees.

Travel Times and Schedules

Always double-check the latest flight and ferry schedules shortly before your departure date. Inter-island transport schedules in the Caribbean can sometimes be subject to change due to weather conditions, mechanical issues, or other unforeseen circumstances. Building in a buffer for connections is always a good idea.

Union Island serves as an excellent base for exploring the breathtaking beauty of the Southern Grenadines. From its main town of Clifton, you can easily arrange day trips or multi-day excursions to nearby jewels. Consider a short boat ride to the iconic Tobago Cays Marine Park, famous for its vibrant reefs and swimming with turtles.
