Set inside The Dubai Mall, the Dubai Aquarium is one of the largest in the world, with a 10-million-litre tank that houses more than 140 species of marine life, including the planet’s biggest collection of sand tiger sharks. A stroll through the 48-metre walk-through tunnel gives you a front-row seat as sharks and rays glide overhead, while the underwater zoo upstairs introduces visitors to everything from otters to penguins.

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.

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.

A winding stone bridge links the mainland to this rocky islet, followed by 240 steps up to the small hermitage of San Juan de Gaztelugatxe. The chapel dates back to the 10th century, although it has been rebuilt multiple times following fires and pirate attacks. Even if the chapel is closed (which it often is), the climb is worth it for the stunning sea views, the cliffs carved into arches, and the remote, windswept feeling at the top - Game of Thrones fans will recognise the setting as Dragonstone. It’s about a 45-minute drive from Bilbao. You can also take a bus to Bermeo, a fishing town nearby, and continue by taxi or local bus. The trail is steep and uneven, so good shoes help.
