San Juan to Fort Lauderdale

Puerto Rico’s capital makes a strong impression – even before you arrive on shore. Sailing into the harbor, keep an eye out for El Morro, a 16th-century citadel and UNESCO World Heritage Site, Castillo San Cristobal, a fearsome fortress built to scare away invaders, and La Fortaleza, the impressive official residence of the Governor of Puerto Rico. Once ashore, step back in time along cobbled streets and through squares flanked by pastel-colored Spanish colonial buildings. Or take your pick of beaches – will it be the golden-sanded Isla Verde, the snorkeler-approved El Escambrón, or the laid-back Ocean Park? Just don’t leave San Juan without sampling a piña colada (or two) – the tropical cocktail was invented here in the 1950s.

Basseterre is the compact coastal capital of the Caribbean island St. Kitts, where verdant hills and sugar-white sands meet architectural artefacts of French and British colonial rule. The town center is anchored by Independence Square – formerly Pall Mall Square – an 18th-century plaza with an ornate fountain and lush lawn, while nearby, the Georgian-inspired Circus is modeled after London's own Piccadilly. Venture just beyond the city to explore the UNESCO-listed Brimstone Hill Fortress National Park, an 18th-century British-built fortress that offers sweeping views and serves as a striking reminder of the island’s layered history.

Dominica is the nature lover’s retreat from the rush of daily life, a fragrant tangle of rainforest that is easily explored from its capital, Roseau. The tiny volcanic island offers both golden- and black-sand beaches to loll on – Batibou is a dazzler – but it’s the wild beauty of its interior that enchants. Hike through the Titou Gorge, familiar from the moviePirates of the Caribbean: Dead Man’s Chest, dipping into the chasm’s cool waters to swim to the waterfall at its end. Climb into the mountains at Morne Diablotins National Park (one of three on the island) for the chance to catch sight of the sisserou parrot. And delve into history at Fort Shirley, scene of an important slave revolt. Snorkeling in the bubbly, volcanic waters at Champagne Reef, shopping for handcrafted gifts at the Old Market, and watching out for sperm whales – this is the only country whose waters they live in year-round.

Antigua and Barbuda beckon with their pristine beaches and vibrant history. For beach enthusiasts, Antigua presents a different shore for each day of the year, like the tranquil Half Moon Bay. Adventure seekers can explore the mysterious caves at Two Foot Bay in Barbuda, offering a glimpse into the island’s natural wonders.

History buffs will find Nelson’s Dockyard, a UNESCO World Heritage site in Antigua, a compelling visit, showcasing the island's rich naval history. For a unique experience, take a boat tour to the Frigate Bird Sanctuary in Barbuda, one of the world’s largest, to observe these magnificent birds in their natural habitat. Culinary explorers can delight in the local cuisine, with seafood and Creole dishes highlighting the islands’ cultural melting pot.

St. John’s is the compact, colorful capital of twin-island nation Antigua and Barbuda and an ideal base for exploring all that the islands have to offer. Step off the ship straight into the heart of the action: wander bustling markets; admire pretty, pastel-hued buildings; and discover historic sites like the neo-Baroque St. John's Cathedral and the Museum of Antigua and Barbuda, housed in the 18th-century Old Court House. Many of Antigua’s beaches are within easy reach of St. John’s, so take your pick. Dickenson Bay is a hit with swimmers and snorkelers for its calm, clear waters, while the powdery sands of Runaway Beach are perfect for more secluded relaxation.

The pretty, red-roofed harbor town of Gustavia is the beating heart of stylish St. Barts. High-end boutiques, ritzy restaurants, and iconic cocktail bars pepper the palm-fringed streets, while mere minutes from the town center, you’ll find pristine stretches of sand and sparkling waters. Take your pick from dozens of beaches: Anse de Flamands presents camera-ready scenery, Baie de St-Jean has chic beachside bistros, and Anse du Grand Cul-de-Sac is a snorkeler’s paradise. Just don't be surprised if you encounter an A-lister or two – the French-speaking Caribbean island has long been the preferred playground of billionaires and big-name movie stars.

A day at sea with Crystal can be as relaxed or as engaging as you wish. Begin with breakfast on your veranda, take a walk along the Promenade Deck or spend the morning by the Seahorse Pool before retreating to the Aurōra Spa & Salon for a restorative treatment. Enrichment is always close at hand, with lectures, bridge, creative workshops, dance classes, wellness sessions and opportunities to fine tune skills from photography to golf.

Dining is a highlight throughout the day, from relaxed bites by the pool to elegant dinners at venues such as Umi Uma by Nobu, Beefbar or Waterside. As evening arrives, enjoy live music, theatre entertainment, comedy, social gatherings, cocktails in the lounges or a quiet night in with 24-hour in-suite dining.

City meets sea in the coastal metropolis of Fort Lauderdale, Florida. Soak up the sun along vast swaths of pristine white sands, take a scenic boat tour through palm-fringed canals, shop your way along the famous Las Olas Boulevard, and sip refreshing craft beers along the Fort Lauderdale Ale Trail. When it comes to dining, you’re spoilt for choice: from fresh seafood with a waterfront view to Michelin-approved pizza, there’s mouthwatering cuisine at every turn.
