Two miles (3km) off St Croix's northeastern shore, uninhabited Buck Island is one of the best excursions in the Virgin Islands. The whole island (tiny though it is) and the surrounding reef has been declared a nature reserve, meaning you only have to share it with other folk who can be bothered to grab a boat and a picnic in Christiansted. The islet's attractions include an excellent beach, fantastic elkhorn coral and an underwater snorkeling trail that introduces you to the area's copious marine life.

This gorgeous spot is by no means deserted but it's only fair that such beauty gets shared around. Tucked away snugly on the northeastern coast of St Thomas, the water here is sparkling, the sandy beach is dazzling and the fish are so friendly they'll eat from your hand. The snorkeling is great, but it's just as rewarding to grab a fruit shake and let your deck chair do all the work.A short toddle away is the crowded but educational Coral World, an 80,000 gallon aquarium that lets you get eye level with sharks, eels, stingrays and fish without getting so much as your little pinky wet.

St Croix (you can say it 'St Croy') is less developed than rowdy St Thomas, so it's a good place to change down a gear, find isolated beaches and bend the elbow with locals not engaged in the tourist industry. The island, the largest in the Virgin Islands, is composed of forested hills and fertile lowlands and is surrounded by coral reefs. At its commercial height St Croix had about 100 sugar plantations, and decaying plantation houses and the stone towers of their windmills still litter the landscape today.Once the capital of the entire Danish colony, pastel-painted Christiansted has been accused of being the prettiest town in the Caribbean. Clustered around the atmospheric harbor are the clean lines of old Danish warehouses, a customs house, government buildings and a church. Some of the town's oldest buildings are constructed from distinctive Danish bricks that were carried to the Caribbean as ballast. Fort Christiansted, at the eastern end of town, has great views of the harbor and settlement from its cannon-studded ramparts. It was built in 1749 and protected the town from pirates and unruly slaves until 1878 when it was converted to a police station. Also in Christiansted is a flash aquarium notable for the fact that it rotates its fishy residents every few months to keep them perky.Most of St Croix's excellent diving is to be found along its northern coast. The best hikes are in the hilly, forested northwestern corner of the island. The forest peters out in the southwest, turning into salt pans and mangrove. Sandy Point, in the extreme southwest is one of only two leatherback turtle nesting grounds in the Caribbean. If you want to celebrate the continued existence of these enormous creatures, the Cruzan Rum Distillery in nearby Frederiksted gives guided tours and free tastings. Frederiksted is just as cute as Christiansted but the town is largely given over to the duty free frenzy and it dies when there aren't captive cruiseshipping shoppers.

Through the 19th century St John was goopy with sugar and rum, and merchant ships clogged Coral and Cruz Bay. But by the 1950s, when American financier Laurence Rockefeller sailed by, things were mighty quiet. Rocky fell in love with Johnny's perfect white beaches and spectacular views, and did what any of us would do: he purchased half the island, built a secluded resort and campground on the site of an old sugar plantation and donated the remaining 5000 acres (2000ha) to the government. Today, two-thirds of St John is preserved by the Virgin Islands National Park.Largely due to the national park, St John remains tranquil and covered by dense forest. Park rangers with encyclopedic knowledge of the local flora and fauna (which includes mongoose and feral donkeys) lead guided hikes into the interior, and there are twenty-odd trails to explore under your own steam. One of the best hikes is the Bordeaux Mountain Trail, which leads to the 1277ft (383m) summit of the island's highest peak. Two other ridge peaks, Camelberg and Mamey, offer strenuous hikes and rewarding views, while the walk to the Annaberg Plantation takes in the partly restored ruins of an 18th-century plantation house and sugar mill. The national park also encompasses the surrounding waters and reefs, so you'll find excellent snorkeling and marine life, especially at the popular snorkeling trail off beautiful Trunk Bay, and at Reef Bay, Honeymoon Beach and Salt Pond Bay.Development on St John has been restricted to modest Cruz Bay, where the restaurants and bars are concentrated, and shy and retiring Coral Bay, a mere slip of a thing. Ferries connect Cruz Bay with Red Hook and Charlotte Amalie on St Thomas; a weekend ferry zips all the way to Fajardo, Puerto Rico.

This spiky lizard-shaped island has a rambunctious past peppered with the exploits of men named after their facial hair. You'd think the stomping ground of Blackbeard and the mythical Bluebeard would be the last place to turn into the quintessential American beach suburb, but a fine port is a fine port whether you're unloading booty, slaves or cruise ship passengers. St Thomas is overly developed and fixated on shopping but it's also strikingly pretty, thanks to a spine of hills whose forested ridges form headlands separating bays and coves filled with turquoise-blue water. There are more than forty beaches fringing the island, and snorkeling and dive spots galore.Charlotte Amalie (named after the wife of King Christian V in 1691), the capital of the Virgin Islands, has long been a busy port. Today you'd call the town 'lively and bustling' if you were feeling polite, 'congested and harassing' if you'd just had 40 spruikers tell you what lovely watches they have. True enough, the center of town is swamped by cruise ship passengers and duty-free shops, but it does wear its Danish heritage with style. The neat, pastel-painted warehouses, the ochre-colored fort and the dual Danish-English street signs combine to keep it clear that this ain't no mall. The colorful melange of tropical foliage, red-roofed houses and the rich blue bay are best seen from Blackbeard's Castle, atop Government Hill.The town's top ranking historic attraction is Fort Christian, a modest red affair that looks barely fit to defend a string of sausages. The building dates to the 1670s when it served as a combined defense post, government house, church and community hall. When the threat of invasion dissipated, the fort became a jail and, since 1987, a museum with displays on the region's natural heritage (including medicinal plants and birdlife) and art.Part of the island's inglorious past is still standing in Market Square at the other end of Charlotte Amalie. Today the covered plaza is the local food market but it was once the Caribbean's busiest trading post for slaves. Nearby, the Beracha V'Shalom V'Gimilath Chasidim Synagogue was built by Sephardic Jews fleeing the Spanish Inquisition; it's now the oldest continually operating synagogue under the US flag.The island's other attractions include the Virgin Islands panorama at Drake's Seat, a high point in the center of the island from which Sir Francis himself is said to have watched naval engagements. Any self-respecting beach connoisseur should stake out a patch of Magens Bay on the central north coast. Those craving peace and privacy are better off heading to the nearby uninhabited islets of Hassel Island (not hassling at all) and Great St James.Mountain Top, at the peak of St Peter Mountain is higher than Drake's Seat though the surrounding forest means the view is better from lower down. Nevertheless, this is a tranquil spot in between tour buses when you can get a seat at the pleasant bar behind the carpark. Locals claim the banana daiquiri was invented here in an idle moment - boy, does this watering hole have a lot to answer for.

In the early 19th century, when St Croix was one of the region's richest sugar producers, Whim Estate was one of its grandest operations. Today the neo-classical great house, its outbuildings and grounds comprise an evocative museum giving an insight into lives of the plantation owners and the slaves who lived and worked on the property. The main house is notable for its unusual curved walls and the waterless ventilation moat that rings it. Whim is on St Croix a short drive southeast of Frederiksted. Classical musical concerts are periodically held in the grounds.Just 10 minutes east of Whim is the immaculately presented St George Village Botanical Garden. Over 1500 species of plantlife weave and wend around old plantation buildings, workshops and a dinky wedding bower. A walking tour pamphlet helps you find your way around.
