San Miguel de Tucuman
San Miguel de Tucumán is an important historic spot in the country since the Declaration of Independence from Spain took place here on July 9, 1816. The actual place where this important event occurred is a colonial-style house known as "Casa Historica" by tucumanos or "Casita de Tucuman" by Argentineans from other regions. Every 9th of July San Miguel is the capital of Argentina
At Teniente Benjamín Matienzo International Airport, at 9km east from San Miguel de Tucuman, there are 5 daily flights from Buenos Aires with Aerolíneas Argentinas and LAN, one daily flight from Mendoza, one from Rosario and two from Córdoba all of them with Sol Líneas Aéreas. International flights are now suspended, but Aerosur had until 2010 four flights a week to Santa Cruz de la Sierra, in Bolivia, with inmediate connections to Madrid and Miami.
There are two weekly trains from Buenos Aires and back. The journey takes approximately 25 hours as it stops in many towns and cities along the railroad. It costs 87 pesos in tourist class, 132 pesos in Primera class, 236 in Pullman class, and 740 pesos in Camarote class (private two bed compartment and two breakfasts), all round trip prices. There are discounts for students, children and seniors. See the excellent (but only in Spanish) web site: http://www.ferrocentralsa.com.ar/
The train includes a dining and snack car.
Trains leave Buenos Aires Retiro station at 09:55 on Mondays and Fridays and return from Tucumán on Wednesdays at 16:59 and on Saturdays at 19:43. Get your tickets early - they are sometimes sold out 10 days in advance.
There are two tolls of 1,80$ on Ruta 9: one in Leocadio Paz (15 km from the Border to Salta Province) and one in the Border to Santiago del Estero Province. Emergency phone number is *767 (*SOS) from any mobile telephone. Just on Ruta 9 (a tolled Route).
Several bus companies provide services from Tucuman City to almost all major and mid-size cities in Argentina. The city boasts one the largest bus stations in the country and it is located at walking distance from downtown and the main hotels. Bus routes Nr. 4, 8, 10, 102, 103, 110, 118 runs from around the bus station into downtown; Nrs 4, 8, 10, 102, 106, 110 does it in the opposite direction.
The best way to visit the historic area and downtown is on foot. Most attractions are located at walking distance from each other. Besides, the traffic is quite heavy and disorganized so renting a car or taking a taxi would be a waste of time and money. Taxis are all white, with yellow and black stripes. Don't take any other taxi, because they are illegal.
Public Transport (bus) is always a good choice. There are around 40 bus lines, which drives to downtown. A one way ticket cost ARP 2 (about 0,50 U$S) and must be paid to the bus driver in coins. Bus lines 102 and 118 goes to Yerba Buena, an beatiful touristic destination in Tucuman Metropolitan Área. Bus 118 can be reached in Santiago del Estero street (north of the center) while bus 102 on San Lorenzo street (south of the center). A ticket from Center to Yerba Buena costs 1,80$. Bus line 121 to the Airport can be reached on Av. Avellaneda and Av. Gobernador del Campo. A one way ticket costs 1,60$. Just one every hour.
