A panoramic driving tour of Bilbao is a wonderful and relaxed way to see the sights of the city. Accompanied by a knowledgeable guide who imparts lively commentary, this is the perfect way to see it all with little walking involved. The excursion travels along the estuary, passing through Bilbao's industrial outskirts. Drive down the Gran Via, the primary shopping district that reflects the city's 19th-century mining and industrial wealth. Pass the Arriaga Theater and the Arenal Bridge as you approach the heart of the city and its busy commercial core, where in the middle of this modern area stands the neo-Gothic Sagrado Corazon Church. Even from a distance, the Guggenheim Museum is stunning. Get closer and appreciate the masterpiece's titanium curves, designed to be reminiscent of sails and maritime shapes. After admiring this iconic structure, proceed to Casco Viejo, the Old Quarter, to trace the city's past.
