By Bus -- The bus station is on Corso Cavour, to the left of the train station (tel. 800-915-303; www.saf.ud.it). Frequent buses (28 a day) link Trieste and Udine (1 1/2 hr.), and many other towns throughout the region. There's also one bus Monday to Saturday (check for the schedule, as it often changes) to Ljubljana, Slovenia (2 3/4 hr.).

The center of Trieste, which is snuggled between the hills and the sea, is compact and easy to get around on foot. The bus and train stations are at the northern end of the center, on the Piazza della Libertà. From there, follow the harbor south for about 10 minutes along Corso Cavour (you'll soon cross Trieste's Canal Grande) and its continuation, Riva III Novembre, to the Piazza dell'Unità d'Italia. This dramatic space -- with Habsburg-commissioned, neoclassical buildings on three sides, the sea on one side, and a fountain in its center -- is the heart of old Trieste and the present-day city as well. Via Carducci, Trieste's main shopping street, cuts through the center of the orderly 19th-century city. It begins in Piazza Oberdan (a few blocks east of the train station on Via Ghega) and cuts a straight swath south to Piazza Goldoni; from there the Corso Italia leads west to Piazza dell'Unità d'Italia and the sea.
Central Trieste is easily navigable on foot, but the footsore can use the extensive network of TT buses and trams (tel. 040-425-001 or 800-016-675 in Italy; www.triestetrasporti.it) that runs throughout the city. You can purchase tickets at any tabacchi (tobacconist) for 1.05€ for 60 minutes (valid for 4 hr. on Sun) or 3.50€ for a day pass. One foot-saving route is the no. 24 line from the train station to the hilltop Castello di San Giusto and its adjoining cluster of remarkable buildings , or call a taxi at tel. 040-307-730.
