Donosti’s Semana Grande: fireworks, festivities, and pure tradition

In August, San Sebastián undergoes a transformation. It goes from being a city of quiet elegance and scenic walks to becoming one big party. And not just any party: Semana Grande (Aste Nagusia in Basque) is the most eagerly awaited event of the summer in the city. It’s nine days of fireworks, concerts, gastronomy, popular culture, and a great atmosphere from sunrise until long after sunset.

If you’re planning to visit Donosti during this time, do yourself a favor: save your energy, keep your eyes open, and hop on a bike. Because there’s a lot to see, even more to try, and everything to the beat of drums, txupinazo, and txakoli.

History: from cannon fire to fireworks

Although the current Semana Grande is a modern event, its roots are firmly anchored in the 19th century. The first official edition was in 1876, organized by the City Council with the aim of attracting tourism and livening up the summers in San Sebastian. At that time, it was all about bullfighting, dances with orchestras, and “society events.” Everything was very much in keeping with the times.

But the real revolution came in the 1960s, with the addition of what is now one of its biggest attractions: the International Fireworks Competition. Since then, every night during Semana Grande, a different pyrotechnics company competes by putting on a show over La Concha Bay. The entire city comes to a standstill to look up at the sky during those fifteen minutes of lights, color, and music.

The official start is marked by the traditional cannon shot in Alderdi Eder, in front of the City Hall, with a symbolic figure that changes every year: it could be a firefighter, a scientist, an athlete, or someone beloved by the city. From that moment on, there are no more excuses: the party has begun.

Events you can’t miss

Semana Grande isn’t just fireworks and concerts, it’s a non-stop schedule of events. There are activities for all ages, tastes, and energy levels. Here’s a summary of the highlights:

Daily fireworks

Every night at 10:45 p.m., the world’s best pyrotechnicians launch their creations from a floating platform in the bay. They can be seen from almost any high point, but the best spots fill up quickly. Taking a sandwich and your blanket to the Paseo Nuevo or Mount Urgull is a ritual.

Outdoor concerts

From Spanish rock bands to traditional Basque music, jazz, and even international acts. The stages are spread throughout the city: Sagüés, Plaza de la Trinidad, the Boulevard… If you get around by bike, you can hop from one to another without stress or fighting for a spot on the bus.

Theater and street performances

Jugglers, clowns, acrobats, giant puppets, and highly original artistic performances take to the streets throughout the day. Ideal if you are traveling with children… or if you simply want to get carried away by the magic of the moment.

Family activities

There is a parallel program designed for children: workshops, inflatables, storytelling, treasure hunts, and shows designed so that the whole family can have fun without breaking the bank.

Basque sports and local traditions

Did you know that you can watch people lift 150-kilogram stones in the middle of the street? Basque rural sports are an essential part of the festival: aizkolaris (log cutting), harrijasotzailes (stone lifters), sokatira (tug-of-war), and regattas fill the squares and promenades with brute force… and excitement.

Popular cuisine

It’s not all about seeing and hearing. You also have to eat (and drink). During Semana Grande, talos, chorizo in cider, cod, and pintxos are everywhere. There are food fairs, street stalls, and plenty of txakoli to toast with. The terrace atmosphere is continuous.

Fair and stalls

The classic fair with rides, raffles, cotton candy, and a Ferris wheel is set up along the river. It’s the perfect plan for the evening or to extend the night after the fireworks.

Move around like a local (without stress)

During these days, San Sebastián is packed to the brim. And while the atmosphere is part of the charm, it can also be a hassle to get around if you’re not prepared. This is where your best ally comes in: the bicycle.

With Bike Rental San Sebastián, you can get from the beach to the square, from concerts to fireworks, and from pintxo to pintxo, without relying on public transportation or worrying about parking. There are bike lanes throughout the city, and many safe areas to leave your bike while you enjoy the show.

And it’s not just practical: it’s also the most authentic way to experience Semana Grande like a local. You pedal, you stop, you try something new, you move on again… That’s how you really explore Donosti.

Tips for making the most of Semana Grande

• Get to the fireworks early: if you want a good spot, arrive at least an hour beforehand.
• Don’t try to do everything: choose two or three plans per day and enjoy yourself without stress.
• Check the official program on the City Council website or at information points.
• Wear comfortable shoes and bring something warm for the evenings.
• Always have your bike handy: you’ll save time and have the freedom to improvise.

San Sebastián’s Semana Grande is not just a festival. It’s a way of understanding the city, its culture, and its energy, all concentrated into one week. If you’re here in August and want to experience Donosti to the fullest, join in the festive atmosphere, explore without a map, and rent a bike so you don’t miss a minute.

Because in this city, the best experiences aren’t planned… they’re pedaled.
