If you are going to take more than one or two journeys on public transit, a CreditTrans card would be a good investment. It can save you up to 50% over buying single tickets. It is valid on all the municipal transit systems in Bilbao, and most (soon to be all) of the provincial transit systems in Bizkaia. It's a pay per ride card available at all Metro and Tram stations in denominations of €5, €10, and €15. It's also available at many newspaper stands. Individual tickets cost from €1.20 upward.
The Metro Bilbao was designed by Norman Foster. It's a single line metro within Bilbao, splitting into two lines after San Inazio station. Line one runs from Etxebarri to Plentzia; line two from Etxebarri to Santurtzi. Trains run every couple of minutes at peak hours. Tickets cost from €1.40-1.60, depending on how many zones your journey covers, or a daily card is available for €4.
