Courtesy of Hotel Miro in Bilbao, here are some useful tips on what to do in the city of Bilbao:
Casco Viejo (Old Quarter)
Take the bright-green tram in front of the Hotel and go explore the old part of town.
Get lost in the labyrinth of streets and re-fuel having some pintxos in the Plaza Nueva.
Museo de Bellas Artes (Fine Arts Museum)
Located at a stone´s throw from the Hotel, it is definitely a must. It is the third most important collection in Spain. If in a hurry, visit the selection of 16 masterworks from the collection. Tuesday to Saturday, 10am-8 pm, Mondays closed.
Just 20 minutes outside the city, beautiful seaside town with beaches and beautiful turn of the century houses. Cross the Vizcaya Bridge in the first steel shuttle bridge in the world. http://www.puente-colgante.com/en/principal.html
