Bilbao is located in northern Spain and is the largest city in the Basque Country. Make sure you visit the world-famous Guggenheim Museum, as well as the Fine Arts Museum. If your Spanish course in Bilbao happens to take place in the third week of August, you'll be able to take part in the city's main festival, Semana Grande (Big Week), which includes spectacular street shows, firework displays, performances and other celebrations.
