Viseu has excellent motorway links with other major cities, the coast and Spain via the junction of the A25 (east/west) and A24/IP3 (north/south) motorways. There is an outer ringroad consisting of part A25 and IP5. Porto airport is the nearest international airport, about 1 3/4 hours away by car. Viseu has its own municipal airport for light private aircraft. There is no train service. The closest railway stations are in Nelas or Mangualde, both on the Linha da Beira Alta. This makes Viseu the largest city on the Iberian peninsula without a railway station.
