Acapulco (officially known as Acapulco de Juárez) is a resort city in the state of Guerrero on the Pacific coast of Mexico. It is located on a deep, semi-circular bay and has been a port since the early colonial period of Mexico's history. It is a port of call for shipping and cruising lines running between Panama and San Francisco, California, United States. The city of Acapulco is the largest in the state, far larger than the state capital Chilpancingo. Acapulco is also Mexico's largest beach and balneario resorted city. The city is best known as one of Mexico's oldest and most well-known beach resorts, which came into prominence in the 1950s as a getaway for Hollywood stars and millionaires. Acapulco is still famous for its nightlife and still attracts many vacationers, although most are now from Mexico itself. The resort area is divided into two: The north end of the bay is the "traditional" area, where the famous in the mid-20th century vacationed; and the south end is dominated by newer luxury high-rise hotels.
