New Year in St. Barths & the Leeward Islands

If you associate Puerto Rico's capital with the colonial streets of Old San Juan, then you know only part of the picture. San Juan is a major metropolis, radiating out from the bay on the Atlantic Ocean that was discovered by Juan Ponce de León. More than a third of the island's nearly 4 million citizens proudly call themselves sanjuaneros. The city may be rooted in the past, but it has its eye on the future. Locals go about their business surrounded by colonial architecture and towering modern structures.By 1508 the explorer Juan Ponce de León had established a colony in an area now known as Caparra, southeast of present-day San Juan. He later moved the settlement north to a more hospitable peninsular location. In 1521, after he became the first colonial governor, Ponce de León switched the name of the island—which was then called San Juan Bautista in honor of St. John the Baptist—with that of the settlement of Puerto Rico ("rich port").Defended by the imposing Castillo San Felipe del Morro (El Morro) and Castillo San Cristóbal, Puerto Rico's administrative and population center remained firmly in Spain's hands until 1898, when it came under U.S. control after the Spanish-American War. Centuries of Spanish rule left an indelible imprint on the city, particularly in the walled area now known as Old San Juan. The area is filled with cobblestone streets and brightly painted, colonial-era structures, and its fortifications have been designated a UNESCO World Heritage Site.Old San Juan is a monument to the past, but most of the rest of the city is planted firmly in the 21st century and draws migrants island-wide and from farther afield to jobs in its businesses and industries. The city captivates residents and visitors alike with its vibrant lifestyle as well as its balmy beaches, pulsing nightclubs, globe-spanning restaurants, and world-class museums. Once you set foot in this city, you may never want to leave.

Virgin Gorda, or "Fat Virgin," received its name from Christopher Columbus. The explorer envisioned the island as a pregnant woman in a languid recline, with Gorda Peak being her belly and the boulders of the Baths as her toes. Different in topography from Tortola, with an arid landscape covered with scrub brush and cactus, the pace of life is slower here, too. Goats and cattle own the right of way, and the unpretentious friendliness of the people is winning. The top sight (and beach for that matter) is the Baths, which draws scores of cruise-ship passengers and day-trippers to its giant boulders and grottoes that form a perfect snorkeling environment.

You can easily explore all of Gustavia during a two-hour stroll. Some shops close from noon to 3 or 4, so plan lunch accordingly, but stores stay open past 7 in the evening. Parking in Gustavia is a challenge, especially during vacation times. A good spot to park is rue de la République, alongside the catamarans, yachts, and sailboats.

Nassau's sheltered harbor bustles with cruise-ship activity, while a block away Bay Street's sidewalks are crowded with shoppers who duck into air-conditioned boutiques and relax on benches in the shade of mahogany and lignum vitae trees. Shops angle for tourist dollars with fine imported goods at duty-free prices, yet you'll find a handful of stores overflowing with authentic Bahamian crafts, food supplies, and other delights. With a revitalization of downtown ongoing—the revamped British Colonial Hilton leading the way—Nassau is recapturing some of its past glamour. Nevertheless, modern influences are completely apparent: fancy restaurants, suave clubs, and trendy coffeehouses have popped up everywhere. These changes have come partly in response to the growing number of upper-crust crowds that now supplement the spring breakers and cruise passengers who have traditionally flocked to Nassau. Of course, you can still find a wild club or a rowdy bar, but you can also sip cappuccino while viewing contemporary Bahamian art or dine by candlelight beneath prints of old Nassau, serenaded by soft, island-inspired calypso music. A trip to Nassau wouldn't be complete without a stop at some of the island's well-preserved historic buildings. The large, pink colonial-style edifices house Parliament and some of the courts, while others, like Fort Charlotte, date back to the days when pirates ruled the town. Take a tour via horse-drawn carriage for the full effect.
