Welcome to “Things to do in Barcelona!” It’s Thursday, August 21, 2025, and the city is positively buzzing. After a mild morning, Barcelona is basking in summer warmth under bright Mediterranean sunshine—the perfect backdrop for exploring vibrant streets, open plazas, and rooftop events. The air is fresh, and the city’s pulse is quickening as festival season reaches its peak.

Today’s vibe feels festive and historic all at once: **Gràcia’s Big Annual Festival** is painting entire streets with color and creativity, featuring workshops for kids, street concerts, and neighborhood celebrations through the night, as the iconic event wraps up its nine-day run today. For the curious, **The Poet’s Trail: Secrets of Barcelona** tour kicks off at Plaça de Catalunya and invites you on a journey through the heart of the city, weaving storytelling and hidden history into an unforgettable experience[1][6]. If you’re in the mood for more thrill, the interactive **Barcelona Murder Mystery: Catch the Killer!** begins this evening at Plaça del Pi—a great option for sleuths and families eager for a playful challenge through the Gothic Quarter’s twisting lanes[5].

Culture lovers have a special treat: tonight is the last chance to experience Puccini’s “Turandot” at Teatre Apolo, as part of the Summer Opera Festival. Over 70 performers and lavish sets transport you into a world of grand drama—opera fans, don’t miss out[6]. For music with a different vibe, head to Hotel Pulitzer for a rooftop set by Melina Serser, blending ambient and electronic sounds as the sun sets over the city—from 7 to 10 PM tonight[10].

Barcelona’s local news brings exciting updates too. The iconic Camp Nou stadium is nearing the end of its ambitious renovation, with new accessibility features, glistening glass façades, and a freshly painted, match-ready pitch—fans can look forward to its reopening soon, with the promise of a completely modernized FC Barcelona home[3]. Meanwhile, city leadership has confirmed public transit will be running extended hours all weekend due to festival crowds, and residents are abuzz about two new tapas bars opening in El Born, adding even more flavor to the food scene.

Searching for must-do activities today? Don’t leave Barcelona without seeing the storied Sagrada Familia or meandering through the enchanting lanes of the Gothic Quarter—home to Roman relics like the ancient Temple d’August and the Chapel of Saint Agatha[2][4]. Nature lovers can escape to Montjuïc Hill for panoramic views, lush gardens, and shady trails—a serene break from the festival crowds[8]. For something unconventional, pop into the playful Erotic Museum on La Rambla, or grab a bike and join a local tour to hit both highlights and hidden gems.

A local tip: in Gràcia, look for the streets decked with fantastical handmade decorations. Every year, neighbors compete to craft the most creative displays—this is your chance to see community spirit and Catalan pride at its most dazzling and authentic.

Looking ahead, tomorrow launches Festa Major de Sants, another beloved street festival full of music, food stalls, and cultural flair. Plus, don’t miss Clandestine’s house and disco set at Hotel Pulitzer Friday evening, and fresh planetarium adventures for families at CosmoCaixa over the weekend.

That’s your peek into an exhilarating Barcelona Thursday. Tune in tomorrow for the latest happenings, secret spots, and more ways to make every day in Barcelona unforgettable!
