Caribbean cruise guide: routes, islands and when to go
Eastern, western or southern? How the routes compare, when to sail and how to plan a Caribbean cruise.
The Caribbean is the world's most popular cruise region for good reason: warm water, short hops between islands and a huge choice of routes. But "a Caribbean cruise" can mean very different trips — a beach-heavy week in the west, a historic island loop in the east, or a southern route closer to South America. This guide helps you tell them apart.
The three main routes
| Route | Typical islands | Feel |
|---|---|---|
| Eastern | Puerto Rico, St. Thomas, St. Kitts, Antigua, Barbados | Colonial towns, beaches, more sea days |
| Western | Cozumel, Grand Cayman, Jamaica, Roatán, Belize | Reefs, ruins and adventure |
| Southern | Aruba, Curaçao, Bonaire, Grenada, St. Lucia | Drier islands, fewer crowds, longer flights |
Eastern Caribbean
The eastern route is the classic island-hopping week: San Juan, St. Thomas, St. Kitts and Antigua, often finishing in Barbados. Expect historic towns, duty-free shopping and some of the best beaches. It suits first-timers who want variety. For a taste of the region's port cities, see our guides to San Juan and Nassau.
Western Caribbean
The west leans towards reefs, ruins and adventure: Cozumel and Grand Cayman for diving, Jamaica for waterfalls, Roatán and Belize for snorkelling and Mayan sites. It's popular with families and with anyone flying in from the US, since the ports are close to Florida and Texas.
Southern Caribbean
The southern route, often sailing from San Juan or Barbados, reaches Aruba, Curaçao, Bonaire and the Grenadines. These islands are drier, the crowds are thinner, and the diving is superb — but you'll often fly further to reach the start.
Dry season vs hurricane season
The Caribbean has two seasons, and they shape everything.
- Dry season runs roughly December to April: sunny, warm and the most popular — book early.
- Hurricane season runs June to November, with the peak later in the season. Cruising still happens, but routes can change at short notice.
- The shoulder months of May and November often give the best balance of weather and value.

Private islands
Many lines run their own private islands in the Bahamas and the Caribbean. They usually mean a beach day with lunch, water sports and an easy, controlled experience — no taxis and no currency to worry about. Great for families, but they're a curated slice of the region rather than a real port town.
What to pack
- Light, breathable clothes and a couple of smarter outfits for evenings.
- Reef-safe sunscreen, a hat and sunglasses — the sun is strong all year.
- Water shoes for rocky beaches, and insect repellent for humid islands.
- A light rain layer: short tropical showers are common even in the dry season.
- Cash in small notes for taxis, markets and tips, plus a card.
Budget basics
How much a Caribbean cruise costs depends less on the islands than on when you sail, your cabin and the extras. To keep costs down:
- Sail in the shoulder season for the best balance of price and weather.
- Choose an interior cabin if you'll be ashore most days.
- Treat specialty dining, drinks and excursions as real extras and budget for them.
- Book popular excursions early — they're cheaper and more available before sailing.
How to choose
- Decide whether you want beaches, history or reefs first.
- Match that to east, west or south, and check the actual port list.
- Pick your season with weather and budget in mind.
- Read the port guides for the stops you care about most.
The Caribbean rewards a clear plan: choose the route that matches what you enjoy, sail in a sensible season, and treat each port as one good experience rather than a checklist.
