Start at Plaza Unamuno, enjoying a coffee and a bollo de mantequilla at Café Lago. Walk a few meters up to the Archaeological Museum, or simply stroll toward the Church of San Nicolás.
Head down Somera Street, soaking in the local atmosphere and browsing shops like Sorginarte, known for Basque bijouterie and magical objects.
At the Fountain of the Seven Streets, snap a photo and continue along Tendería Street, where you’ll find Boulevard Bookstore, featuring contemporary Basque authors, and Orriak, a charming shop for illustrated gifts.
End your walk at the Cathedral of Santiago—entry is free unless you visit the museum—and on your way out, pick up a souvenir at La Quesería or the artisan market if it's the weekend.
