The Nervión River threads through Bilbao and, on a cool morning, the stone bridges dare you across to Casco Viejo — the Old Town where alleys tighten and history leans close.

Casco Viejo is Bilbao’s medieval core, expanded in the 14th and 15th centuries and reshaped by trade and river traffic. The area’s buildings show layers of style from Gothic church portals to 19th-century eclectic facades like Palacio Yohn. Geologically, the basin’s alluvial plain gave way to quarrying stone that built the city; locally quarried limestone and wrought-iron details are visible on façades. Culturally, the Old Town pulses with pintxo bars, Basque language signage, and public squares used for markets and concerts.
Practically: expect 70–100 minutes of walking across paved and cobbled streets, with short stair sections; the route is self-paced and fully phone-guided. Start early to avoid weekend crowds, wear grippy shoes for cobbles, and keep a portable battery charged — the game runs in the Questo app. Public transport links are nearby and the experience is family-friendly and accessible for most fitness levels. Take breaks in Plaza Unamuno or at a riverside terrace; treat the city with care — these streets are living history, not a backdrop.
