An interesting way to travel is to choose an walking, hiking or trekking tour using the public transportation. In this way you could see and feel much better the difference between cultures, traditions and local habits.
    
Bucharest has an extensive network transportation: subways, trams, trolley and buses which helps us to move fast from a place to another. There are very good connections between tourists sights and there’s no need for private car to make a tour if it’s a beautiful weather and you want to be dynamic.

There are also country tours that could be made using public transportation: train or buses, in a very fast and comfortable manner.
