Euskadi This Week (August 08 -14): Top Events and Weekend Plans

Every August, the vibrant city of San Sebastián (Donostia) bursts into life with Aste Nagusia/Semana Grande, the city’s most iconic festival. Also known as Aste Nagusia in Basque, this week-long celebration is a true showcase of Basque identity, blending tradition, modernity, and an unbeatable festive spirit.

From the firing of the cannon at Alderdi Eder that marks the official start, to the spectacular fireworks competition that lights up La Concha Bay every night, Semana Grande offers unforgettable moments for locals and visitors alike.

But beyond the music, parades, and street performances, it’s also a time to celebrate Basque gastronomy. Pintxo bars overflow with creativity, local cider and txakoli flow freely, and traditional food fairs allow you to taste the essence of the Basque Country. Whether it’s a grilled txuleta, freshly caught seafood, or sweet talos filled with chocolate, flavor is at the heart of the fiesta.

Throughout the city, you’ll also encounter giant puppets (gigantes), traditional sports like stone lifting and wood chopping, and the contagious rhythm of Basque drumming groups. It’s a perfect opportunity to immerse yourself in Basque culture, language, and way of life.

At Basqvium, we invite you to experience Semana Grande not just as a festival, but as a living expression of everything that makes the Basque Country unique — its people, its flavors, and its passion for celebrating life.
