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.
