The capital city of Puerto Rico, San Juan is one of the busiest ports in the Caribbean and a third of all Puerto Ricans live here. Nearly every visitor to the island arrives at San Juan, many on cruise liners. The port is the largest home-based cruise port in the world, hosting 28 vessels and with more being added to the list each year.<br /><br /> San Juan is divided into three distinct districts: Old San Juan, the historic walled city; the beach and resort area; and the outlying suburbs. Tourists are concerned mainly with Old San Juan, the site of most restaurants, shops, entertainment venues and the beaches. The old city is linked to the new by the largely residential Puerta de Tierra area, and a series of modern highways leading to the Condado beach front, which is reminiscent of Florida's Miami Beach with its high-rise hotels and apartment blocks.<br /><br /> It is not only tourism that keeps the financial mills grinding in San Juan. The city is an important centre for petroleum and sugar refining, brewing and distilling, and the manufacturing of cement, pharmaceuticals, metal products and tobacco products. In the midst of all the hustle and bustle there are numerous attractions in San Juan to amuse, entertain and interest the many tourists, and the city is a perfect base for exploring the rest of what this small Caribbean island has to offer.<br /><br />

Old San Juan

Address: San Juan

This area, encompassing about seven blocks, dates back about 500 years to the Spanish occupation when it served as a military stronghold that even withstood Sir Francis Drake's armies. The original cobbles on the streets are blue-tinged, and were originally used as ballast on Spanish ships. The ancient stones set off the more than 400 restored 16th- and 17th-century Spanish colonial buildings that fill Old San Juan and draw thousands of tourists to walk the narrow, steep streets every day. The old town is enclosed in amazingly thick, high walls and features numerous attractive plazas bearing sculptures and memorials.<br /><br />

Fort San Felipe del Morro

Address: San Juan

The mighty six-level fortress of San Felipe del Morro, built in 1540, towers 140 feet (43m) above the sea on San Juan Bay, its 18-foot thick (5m) walls having proved a worthy defence against invasion. The largest fortification in the Caribbean, it is a maze of tunnels, dungeons, barracks, lookouts and ramps, offering spectacular views from atop its ramparts. Also in Norzagaray Street, Old San Juan, is El Morro's partner in defending the city, Castillo San Cristobal, built in the 17th century to a confusing and intricate modular design.<br /><br />

La Fortaleza

Address: Fortaleza Street, Old San Juan San Juan

The Fortaleza was built in 1540 as a fortress to guard the entrance to the San Juan harbour, but later became the official Governor's residence. During succeeding centuries the original structure has been remodelled and expanded, with a neoclassical façade being added in 1846 to leave the building with its palatial aspect. The current governor of Puerto Rico is in residence - the 170th Governor to live in the Fortaleza.<br /><br />

Museo de Arte

Address: 299 De Diego Avenue, Santurce San Juan

Puerto Rico's showcase art gallery opened just a few years ago at a cost of millions of dollars. The gallery is housed in a former city hospital in Santurce and offers a permanent and visiting exhibition. The aim is to highlight the island's heritage through the work of local artists, such as Francisco Oller, who studied in France with Cézanne, and Jose Campeche, a late-18th century Classical painter. The museum has been described as a 'living textbook of Puerto Rico', providing on overview of centuries of the island's history through the medium of art. The museum also hosts events like concerts and festivals throughout the year.<br /><br />

Caribbean National Forest (El Yunque)

Address: San Juan

The Caribbean National Forest, 35 miles (56km) east of San Juan, is the only tropical rainforest in the United States National Park system and was named El Yunque by the Spanish. Its 28,000 acres contain about 240 different species of tree and numerous other plants, from tiny, delicate wild orchids to gigantic ferns.<br /><br /> Visitors can start their visit at the El Portal Tropical Forest Centre where there are films, exhibits and interactive displays on the rainforest. Maps are available of the dozens of walking trails through the forest, graded according to difficulty. Nearby is Puerto Rico's best beach, Luquillo Beach, famous for its soft white sand and towering coconut palms.<br /><br />

Casa Bacardi Visitor Centre

Address: Bay View Industrial Park San Juan

Undoubtedly one of the top tourist attractions in Puerto Rico, a trip to the Casa Bacardi Visitor Centre is a must for travellers to San Juan. Following their exile from Cuba in the 1950s, the Bacardi family moved to Puerto Rico and set up a small rum distillery on the outskirts of San Juan. Today, that small distillery has grown into the largest in the world - producing a jaw-dropping 100,000 gallons of rum per day, and 21 million cases per year.<br /><br /> Tours of the Casa Bacardi Visitor Centre last about an hour, as visitors are shown around a variety of exhibits (including vintage rum stills) and informed about the history of Bacardi rum (including a short movie). The tour culminates in a visit to an on-site, classically-styled bar, where a bartender will show you the 'proper' methods of preparing Cuba libres and mojitos. The best part? All visitors receive two complimentary drink tickets, which they can cash in on ice-cold Bacardi-based drinks. There is also a gift shop located on the premises, a perfect place to pick up some rum or Bacardi apparel for friends back home.<br /><br />

Isla Verde

Address: San Juan

Isla Verde ('Green Island') is San Juan's hippest area, and home to many of its best beach resorts and upmarket hotels. The area's name is inspired by the colour of the water in its bay: a rich, green-turquoise shade that will prove irresistible to swimmers and divers. While the beautiful crescent-shaped beach - with its soft sand and tall palm trees - is a tourist attraction in its own right, most visitors to Puerto Rico will seek out Isla Verde for its excellent beach resorts, plush hotels, international dining options, world-class spa treatment facilities and vibrant nightlife. Isla Verde is home to two of the island's best casino hotels and a wide range of raucous night clubs and bars, where live local music is often staged. A natural base for well-heeled travellers to San Juan, Isla Verde makes for a luxurious home away from home during your holiday in Puerto Rico. A fantastic winter sun vacation destination, Isla Verde sees most of its tourist activity between December and January, when days are warm and sunny and there is no threat of hurricanes or storms.<br /><br />
