Bilbao is a great city to stroll around and the old town area, Casco Viejo, is full of beautiful Basque architecture and interesting sights.
The maze of interconnecting alleys feels a little like a rabbit warren, but navigating yourself around is all part of the fun. The historical seven streets, the oldest part of the neighborhood, feature many bars and restaurants packed with laid-back locals. The Mercado de la Ribera, reputably the largest indoor market in Europe, is adjacent to the seven streets and well worth a visit. The elite traveler can expect to find many locally produced goods, fruits, vegetables and other delicious foods. Plazas Nueva and Unamuno with their traditional Spanish style are great places to eat and drink, while the Iglesia de San Nicolás is a beautiful 14th century Gothic church.
