Bahía Blanca’s bus terminal is 2km southeast of Plaza Rivadavia. Taxis to the city center cost around AR$60-AR$70; local buses 514 and 512 run to the bus station from Plaza Rivadavia, but you'll need to acquire a SUBE bus card from a municipal kiosk before you ride, which makes catching a bus into town from the terminal a challenge. On the way out, however, it's easy enough, provided you've procured that SUBE card, which won't cost anything, but you will need your passport to get one. After that you'll need to hit a kiosco to add money to the card. It's all doable with some patience.
There are several businesses – including kioscos and locutorios (private telephone offices) – around the south end of Plaza Rivadavia that sell long-distance bus tickets, saving you a trip to the bus terminal. These businesses sell different bus companies’ tickets, so ask around if you want a particular schedule, company or price. Dakar is a good place to start.
Travelers to Sierra de la Ventana have two options: Condor Estrella runs two daily buses (AR$160, 2½ hours) and Norte Bis operates a door-to-door shuttle (AR$200, one hour) with two or three departures per day. Call ahead to reserve a spot.

Practical Tip: Getting to the Port
Unless you have a rental car, you have two options for getting to Ingeniero White (the port neighborhood) from downtown Bahía Blanca. Option one is to take bus 500 (30 to 40 minutes) from the south side of Plaza Rivadavia. Option two is to take a 20-minute taxi ride (AR$200 one-way). Coming back, there are also taxis available, parked at the stand near Museo del Puerto.
Trains run from the Estación Ferrocarril Roca to Buenos Aires' Constitución station several days of the week (AR$750 to AR$2625, 14 hours). Check www.sofse.gob.ar for more details on routes and fare options, and to make reservations.
