Take bus no 1 or 3 to the Ibla. The last bus leaves the tourist office at 8.40pm. If you go there on foot do not follow the directions for cars but take the step streets down from Via Roma. In Ragusa there are 15 lines of local bus, mainly circular lines, run by AST (Azienda Siciliana Trasporti). You can buy bus tickets at Tobacco shops and News Agents.
There is a taxi station/office at the beginning of Ragusa Ibla in Piazza della Repubblica and there are taxis at the train station in the new Ragusa.
