Most of the faculties of the Universidade da Coruña are in the Elviña and Zapateira campuses, 6,6 km (4 miles) from the city centre. To reach them you need to take the urban buses.
The E‑Universidad / UDC bus line connects the city centre (Juan Flórez street, no. 10, near the Plaza de Pontevedra) with these two campuses. During the course, the bus runs every 5 minutes during the rush hours.
You'll find information about routes, timetable, possibility for trasbordo (changes) in the Coruña buses, etc. at the bus company webpage: http://www.tranviascoruna.com/es.
