Is it cheaper to fly or take the ferry?

Ferries are significantly cheaper and more reliable for short distances, though they can be rough in heavy seas.

Do I need to book ferries in advance?

For most inter-island ferries, you can buy tickets at the dock 30-60 minutes before departure. High-speed ferries during holidays are the exception.

How to plan an island-hopping trip in the Caribbean

Focus on a single sub-region like the Grenadines or the Virgin Islands to minimize transit time and maximize beach time. Limit your trip to three islands over 10 days to avoid spending your entire vacation in ferry terminals or security lines.

Pick a cluster. Don't try to cross the entire Caribbean. Choose a 'hub' with frequent inter-island connections, like St. Vincent and the Grenadines (fast ferries) or the BVI (water taxis). Crossing major distances usually requires expensive, infrequent regional flights.
Prioritize ferry routes. Check ferry schedules before booking your flights. Many islands only have connections on specific days of the week. Build your itinerary around these maritime links.
Book regional flights strategically. If you must fly between islands, use regional carriers like LIAT or InterCaribbean. Book these separately from your long-haul international flight, but leave at least 4 hours of buffer time for connections.
Manage your base. Avoid changing hotels every single night. Spend at least 3 nights per island to actually explore beyond the cruise port or airport area.
