Antigua and Barbuda are located in the Eastern Caribbean’s Leeward Islands approximately 17 degrees north of the equator. Antigua is the largest of the English-speaking Leeward Islands, and encompassing 108 square miles, measuring 14 miles long and 11 miles wide. The highest point is Boggy Peak (1,319 feet) in the southwestern corner of the island. Barbuda is a flat coral island encompassing only 68 square miles, and lies approximately 30 miles due north of Antigua. The nation also includes the tiny uninhabited island of Redonda, a nature preserve.

St. John's, the capital and largest city, is dominated by the white baroque towers of St. John's Cathedral. Built in 1845, the church is now in its third incarnation following earthquakes in 1683 and in 1745 which destroyed the previous structures. Antigua’s cruise ship dock is located in St. John, and the island is a favorite Caribbean port-of-call for cruise ships. St. John also features several hotels and is a lively hub for shopping and dining. English Harbour is Antigua's historic district, located on 15 square miles in Nelson's Dockyard National Park. Developed as a base for the British Navy, the harbor served as the headquarters of the fleet of the Leeward Islands during the turbulent late 18th century.

Other historic attractions include Shirley Heights, an array of gun emplacements and military battlements named for General Shirley, Governor of the Leeward Islands when the area was fortified in the late eighteenth century. The site overlooks English Harbour, and informal Sunday afternoon gatherings here feature barbecue, rum punch, and the plangent steel band and reggae music. The Museum of Antigua and Barbuda tells the nation’s story from its geological history through the present day. Located in St. John's, the museum features a variety of noteworthy objects and exhibits, including a life-size replica of an Arawak dwelling and the bat of Viv Richards, one of the greatest cricket players of all time.

Sea View Farm Village is among Antigua’s signature cultural attractions. Antiguan folk pottery dates back to the early 18th century, when slaves fashioned cooking vessels from local clay. Today, Sea View Farm Village is the center of this cottage industry. Folk pottery can be purchased at outlets in the village and at several stores around the island. Buyers should be aware that Antiguan folk pottery breaks easily in cold environments.
