Bucaramanga is a medium sized city, home to nearly 1 million inhabitants (all of the metropolitan area). It's a major commercial hub in northeastern Colombia, playing a significant role in trade between Colombia and Venezuela. It's not a huge touristy destination like Cartagena or Santa Marta but nonetheless it is surrounded by beautiful landscapes and ancient towns with a lot of history, which overall makes the visit to Bucaramanga worthwhile.
As always in Colombia, foreigners are NOT advised to travel by car alone. You can go out with your family, your friends or with a guide with no problem. They will take you to their farms, nearby towns and resorts without problems.
Palonegro Airport (BGA) is located about 45 minutes from town near Lebrija. Domestic flights include Bogotá, Medellín, Cúcuta and Yopal, and it recently started its first international flights to Panama City, with renovations underway to further expand its flights. . There is also a new flight to Fort Lauderdale USA, via Aires with a layover in Cartagena but its a short layover 20 min and you do the customs and Immigration in Bucaramanga.
The city offers a clean, modern and nice bus station (La Terminal de Transportes de Bucaramanga) from where you can take busses to almost any destination around Colombia; you can even take buses from here that will take you to Venezuela, Perú and Ecuador. There are frequent 10 hour buses from Bogota for prices starting from COP 40 000.
There are many public and private transportation companies that offer bus services and cover almost all of the metropolitan area (Bucaramanga, Girón, Floridablanca and Piedecuesta). It's a cheap and a rather safe way (ticket costs around US$ 0.45). However, it will cost more depending on the bus, the route, and the day traveling around Bucaramanga. They offer nice and clean vehicles that you will make you feel comfortable. If loud music is not your preference then this transportation option could be a problem for you. Most of the drivers enjoy their loud music, but this doesn't happen in most cases.
As stated above, foreigners should not take buses if they are traveling alone. Especially to some 'hot' (dangerous because of the conflict) places like Villavicencio and Barrancabermeja, which are advised to use air services instead. The road that links Bogotá with Bucaramanga is safe, and you can freely travel on this road or take buses with no concern. This road also offers some excellent spots worth checking out, like the Chicamocha Canyon, the towns of San Gil, Socorro, Vélez and Barichara, among others.
Opened in December 2009, the new bus system rides by exclusive lanes making many trips faster and more comfortable. It is safe a clean. 
This is by far the best way to travel around if you don't mind spending a bit more for transportation. The cabs here are very clean, safe and they will take you anywhere you want. However, if you ride a cab, please make sure that you get the plates written down somewhere, and as an advice, it would be better if you call the company and request a cab.
