The centre of Ruse is compact and walkable. The pedestrianised zone around Freedom Square and along Aleksandrovska Street is where most of the sights, cafes, and restaurants are clustered — you can cover the main attractions on foot in a morning.
City buses serve the wider residential areas and the train station, which is east of the centre. Taxis are inexpensive by Western European standards and readily available around Freedom Square; use metered cabs or agree on a price before getting in. For the Ivanovo Rock Monastery, the local bus from the main bus station is the easiest option if you don't have a car.
