Visiting San Sebastian, nestled on the northern coast of Spain, is a must for any traveler seeking a unique blend of cultural experiences, stunning scenery, and culinary delights. Here is a list of the best things to do while in this enchanting city:

1. Indulge in Pintxos: Pintxos are the Basque country’s answer to tapas and are an absolute culinary necessity when in San Sebastian. Head to the Old Town (Parte Vieja) where bars line the streets, each one offering its unique twist on these bite-sized gastronomic treasures.

2. Relax on La Concha Beach: Arguably one of Europe’s most beautiful city beaches, La Concha is perfect for lounging by the sea. Its crescent shape, golden sands, and clear waters make it a favorite spot for swimming, sunbathing, and water sports.

3. Take in Views from Monte Igueldo: For panoramic views of San Sebastian and its bays, take the funicular railway up to Monte Igueldo. The summit also hosts an old-fashioned amusement park which adds to the charm and appeal.

4. Explore Aquarium Donostia-San Sebastian: Situated at the end of the port, this aquarium is one of the most modern in Europe. It offers an impressive walkthrough underwater tunnel and provides insight into the maritime history and local marine life.

5. Wander through Parte Vieja: The Old Town is not only home to amazing pintxos bars but also full of historical buildings, narrow streets, and vibrant plazas that are best explored on foot.

6. Discover Contemporary Art at Tabakalera: Once a tobacco factory, Tabakalera has been transformed into an International Centre for Contemporary Culture, offering exhibitions, films, performances and more.

7. See La Iglesia de Santa Maria del Coro: A stunning Baroque church located in the Old Town is well worth a visit for its rich interior and magnificent altarpiece.

8. Enjoy Cultural Events at Kursaal Congress Centre and Auditorium: Designed by architect Rafael Moneo, Kursaal is an architectural masterpiece set right on Zurriola Beach and is host to numerous events including film festivals and concerts throughout the year.

9. Walk Along Paseo Nuevo and Feel the Power of Wind Combs (Peine del Viento): This coastal walk provides dramatic ocean views which culminate at Eduardo Chillida’s iconic Wind Combs sculpture set into rocks against crashing waves.

10. Taste Michelin-Starred Cuisine: San Sebastian boasts more Michelin stars per capita than anywhere else in the world. Plan a meal at celebrated restaurants such as Arzak or Mugaritz for a truly exceptional dining experience.

11. Visit Palacio de Miramar: The Miramar Palace offers not only historic significance as it was once the summer residence for Spanish royalty but also provides beautiful gardens with views overlooking La Concha Bay.

12. Attend San Sebastián International Film Festival: If you’re visiting in September, be part of one of the most prestigious and longstanding film festivals that rivals Cannes when it comes to world cinema showcases.
