Sunbathing, diving, fishing and boating are the main daytime amusements in the Bahamas, whose capital Nassau, stands on New providence Island. Tourists can shop in the bustling ‘straw market’ where local vendors create unique straw goods on the spot – alternatively, they can visit the more sophisticated shops in Bay Street. The 18th century Fort Charlotte, on West Bay Street has a moat, open battlements, dungeons and a magnificent view of the harbour. The nearby Ardastra Gardens have tropical flowers and pink flamingos. The Queen’s Staircase, at the top of Elizabeth Avenue, is a 40m (102ft) climb up steps carved into the limestone leading to Fort Fincastle (built in 1793 in the shape of a ship’s bow). The steps can lead to the Water Tower, the highest point in the island, 85m (216ft) above sea level. Here an elevator takes visitors to an observation deck which offers fantastic panoramic views. There is an underwater observatory and marine park just a few minutes away from downtown Nassau. Visitors descend below the water surface to view the feeding of sharks (every day at 1430) and a multitude of exotic marine life.
