Bikes

For the more energetics, cycling is often the quickest and always the most pleasurable way to get around Buenos Aires. The city is almost completely flat with a network of bike lanes now covering more than 130km. You can find various hire companies in the city. Several companies run cycling tours taking in BA's top sights but if you want to use a bike for free, you can use the Public Bicycle Sharing System. The service is free of charge and is available 24 h. You will have to register to use the service:
Online: Register as a user or download the BA Ecobici app on your cellphone. (You will only have to attach your scanned ID into the system). In Person: Request an appointment on buenosaires.gob.ar/turno or calling 147. Go to the communal office and present your ID. For more info check the city website: Ecobici for tourists

BUS (Colectivo)

An other way to travel is taking the public buses, called "collectivo". This is more complicatd for a tourist as they are a lot of lines, a same bus line can use different routes and if you don't pay attention to the sign on the lower left hand corner of the windscreen detailing its routing, you may be in for a surprise. To travel by bus or subte (underground metro) in Buenos Aires, you'll need to get a rechargeable SUBE travel card (ARS$25.00) and charge it with credit. SUBE cards are available at subte stations, at the eight Tourist Assistance Centers and at many "kioskos" (corner shops selling confectionary and tobacco) throughout the city. Cards can be charged with credit at all subte stations, national lottery outlets, and at some kioskos with automated terminals. To find your nearest point of sale, the SUBE website has a map of SUBE vendors. https://www.argentina.gob.ar/sube Note that SUBE can be used in all public buses, as well as subway and trains.
Each time you take the bus, the system tells you how many pesos are left. The service works 24/7, and frequency varies from 3 to 40 minutes, it depends on the time of the day, the bus line, and whether is weekday or weekend. On June 2018, the ticket is between ARS$10.50 and $11.50. Tell the bus driver where you are headed (give the name of the crossroad nearest to where they wish to get off) and he will select the correct fare. The "Metrobus" is a bus rapid transit sytem using dedicated bus lanes to cut journey times on several of the city's main arteries. Several Metrobus stops have free WiFi access.


SUBWAY (Subte)
The Buenos Aires subte was the first underground metro (subway) system in Latin America (line A opened in 1913), and it's often the quickest way to get around the city, especially when travelling to and from the downtown area. There are six lines (lineas) A, B, C, D, E and H, which connect the city's main avenues, train stations and coach stations. Lines A, B, C, D and E converge in the centre of the city.
Trains run every three to ten minutes depending on the line, from about 5.30am to 11.30pm Monday to Friday, 6.00am to midnight on Saturdays, and 8.00am to 10.30pm on Sundays and public holidays. Unsurprisingly, trains can get very crowded at peak commuter times (8am-9.30am and 5pm-7pm). The subte website has a detailed map of the network, and you can download a copy of the map as a pdf http://www.buenosaires.gob.ar/subte/mapa-y-combinaciones. Stations have free WiFi access.

TRAIN (Tren)
The train is an option when it comes to reaching neighbourhoods further from the centre, or to visit destinations in Buenos Aires Province, such as Tigre and the river delta. Trains are economical and tickets can be purchased at the stations with cash or you can travel using the SUBE card. Trains for Tigre leave from Retiro Train Station and pass through Belgrano C. a

TOURISTIC BUS
The touristic yellow buses from the company Buenos Aires Bus will take you around the most characteristic neighborhoods of Buenos Aires. The bus route begins in the heart of downtown Buenos Aires, a few meters from the Plaza de Mayo. Buses run every 20 to 30 minutes, depending on the route, and the tour around the city takes 3 hours 20 minutes. It’s a Hop-On/Hop-Off service, which means you can get on and off the bus as many times as you like. The buses run every day (including public holidays) from 9 a.m. to 5 p.m. You can get on at whatever stop you prefer and begin your tour. There are two ticket options: a 24-hour ticket and a 48-hour ticket. Find more info on their page: buenos aires bus

RENT A CAR
Many major car hire companies operate in Buenos Aires, in the city centre and at both Ezeiza (Pistarini) and Aeroparque (Jorge Newbery) airports. To hire a car you need to be over 21 years of age, have owned a driver’s license for at least 2 years and have the means to pay by credit card. While you can often park in the street if there are spaces (a few central areas have parking meters), many people prefer the safety of parking their cars in an ‘Estacionamiento’ (garage). There are hundreds in the city, and you'll rarely have a problem finding one. Just look out for the big ‘E’ signs.

WALK!
There’s so much to see and enjoy in barrios like San Telmo, Palermo Viejo and Soho, Recoleta, Balvanera and the microcentro (the central downtown area) that they are often best explored in your own time on foot. More and more central streets are being pedestrianized, with improved street lighting and more green spaces, greatly reducing car numbers and fumes.
