The Puerto Rico Museum of Art, which boasts more than ten exhibit halls, includes permanent collections and a compilation of Puerto Rican art from the 17th century to the present. There is also a lovely garden with a pond where you can relax and engage in some people-watching.

Inaugurated in 1890, the Arriaga Theatre is a Neo-baroque opera house named after the Bilbao-born composer Juan Crisóstomo de Arriaga, often referred to as the 'Spanish Mozart'. Inspired by the Paris Opera House, it became a key cultural venue in Bilbao. The original theatre burned down in 1914 and was rebuilt, reopening in 1919. Today, it hosts opera, ballet, classical concerts, and theatre productions. Guided tours give a behind-the-scenes look at the staircases, Royal Box, and costume collection.

Perched above Bilbao on Artagan Hill, the Basilica of Our Lady of Begoña was built starting in 1511 on the very spot where, legend says, the Virgin Mary appeared. The church mixes styles: mainly Gothic inside, a Renaissance front with a grand arch, and a belfry added in the early 20th century. Inside, there’s a polychrome wood carving of the Virgin of Begoña ('Amatxu' to locals) from the 14th century. Sailors often used to name their boats after her, and every 15 August (Assumption) and 11 October (Feast of Begoña), the place fills with pilgrims.

Take a walk in the shoes of a local with one of Bilbao’s most popular hikes. Pagasarri, at 673 m, is one of the smaller mountains surrounding the city, and most locals have tackled it at least once. Buses from the city centre take you to starting points around Zabalburu or Peñascal. At the summit, there’s a bar selling bocatas—baguette sandwiches stuffed with tortilla de patata, txistorra, or chorizo. If you’re feeling ambitious, continue on to Ganekogorta at 998 m, just a bit further along the ridge, for more sweeping views of Bilbao and the surrounding hills.
