Filled with inspiring historical sites and enthralling modern attractions, San Diego is a city whose multicultural population enhances its already fantastic natural attributes. Bordered on the west by the sandy beaches of the Pacific Ocean, positioned just across the border from Tijuana, Mexico and home to a military port, the city sees major tourist activity. Popular contemporary destinations like SeaWorld San Diego and the massive San Diego Zoo draw hundreds, while Balboa Park exhibits history with a plethora of museums and attractions grouped in a unified park setting. Awash in the influences of the cultures that have occupied the area, San Diego's past and present blend together seamlessly in its wealth of sights and activities.
