How many days Bilbao actually needs
Two days covers the city properly: one for the Casco Viejo and the riverside, one for the Abandoibarra side and the museums. A third day is what turns a good trip into a memorable one, because it buys you the coast — Getxo, the transporter bridge, or further out towards the Basque shoreline — without cutting anything from the city itself.
Beyond three days, Bilbao works better as a base than as a destination. San Sebastián, Vitoria-Gasteiz and the Rioja Alavesa are all close enough for a day trip, which is exactly the shape Joru's multi-destination planning is built for.
