The boroughs are:

• Centenario — This is the borough with the largest number of factories and maquiladoras. Its largest colony is Ciudad Industrial ("Industrial City"). Three of the city's most important streets, Boulevard Bellas Artes, Boulevard Industrial and Tijuana-Tecate Highway, are located here.
• Centro — This is the historical midpoint of Tijuana; the municipal palace is located here as well as most of the tourist zones, such as Avenida Revolución and the business district. The Tijuana Cultural Center (CECUT for CEntro CUltural de Tijuana) is located here as well as the Plaza Río Tijuana, until recently the largest mall in the state.
• Cerro Colorado — The Cerro Colorado ("Red Hill") is located here and it is surrounded by houses. Because of its height many of the area's antennae for radio and television stations are located on its peak.
• La Mesa — This is the where the Morelos Park, the largest public park in the city, is located, as well as the Plaza Mundo Divertido, the new Macroplaza and the CETYS University.
• Mesa de Otay — In this borough sits the Tijuana International Airport as well as the Otay Mesa entry to the United States. The Tijuana campus of the Autonomous University of Baja California and the Friendship Park are also located here as well as many maquiladoras.
• Playas de Tijuana — This is the westernmost borough of the city bordered by the Pacific Ocean on the west and the United States border on the north. This is where the beaches of Tijuana are located (hence the name) and it is also one of the two exits to the south towards Rosarito and Ensenada.
• La Presa — This is the largest borough in size and the Abelardo L. Rodriguez Dam is located within its limits, hence its name ("Presa" translates as "Dam" in English). The new Corredor Tijuana 2000 s and the Tijuana-Tecate free road run through it.
