What to Do in Barcelona in One Day

Wondering what to do in Barcelona in one day? This itinerary covers the perfect mix of famous sights, local favorites, and hidden gems, all in a logical route you can follow without any stress or overwhelm.

1. Start at Plaça Catalunya

Begin your day at Plaça Catalunya, the heart of the city and the perfect starting point for exploring Barcelona in 24 hours.

The gigantic square sits between the historic Old Town and the elegant Eixample district. Look around and you’ll spot grand buildings, including the iconic El Corte Inglés department store and several early 20th-century façades.

Locals use the plaza as a meeting point, while flocks of pigeons seem to think they own the place. It’s always buzzing with activity, from street performers to shoppers heading down Portal de l’Àngel.

From here, head up Passeig de Gràcia. The city’s most beautiful avenue is home to some of the most famous buildings in Barcelona.

💡 Tip: Plaça Catalunya is also a major transport hub. You’ll find metro lines, regional trains, city buses, the Aerobus, and hop-on hop-off tourist buses. If you’re starting your day by bus or need to buy a transit pass, this is the perfect place to do it.

🕒 Time needed: 20–30 minutes. Take some time to explore the square, snap a few photos, and get your bearings before heading up Passeig de Gràcia.

2. Walk Up Passeig de Gràcia

From the iconic Plaça Catalunya, head north along Passeig de Gràcia, the most elegant street in Barcelona.

It’s lined with designer shops, luxury hotels, and some of the city’s most famous architecture. Keep an eye out for the details under your feet. Even the sidewalk tiles were designed by Gaudí himself.

About ten minutes into your walk, you’ll reach the Block of Discord, where three striking buildings compete for attention: Casa Batlló by Gaudí, Casa Amatller by Puig i Cadafalch, and Casa Lleó Morera by Domènech i Montaner.

A bit farther up, don’t miss La Pedrera (Casa Milà), another Gaudí masterpiece with its wavy stone façade and surreal rooftop chimneys.

This stretch gives you a taste of Catalan modernisme and shows why this part of the city feels like an open-air museum.

If you only go inside one building, choose between Casa Batlló and La Pedrera. Both are worth the time and ticket.

🕒 Time needed: 1.5 to 3 hours. Includes time to admire the architecture and visit either Casa Batlló or La Pedrera.

3. Visit Sagrada Familia

No trip to Barcelona is complete without seeing the Sagrada Familia.

The iconic church is Gaudí’s unfinished masterpiece and one of the most unique buildings in the world. Its soaring towers, detailed façades, and light-filled interior make it an unforgettable experience.

From Passeig de Gràcia, you can walk to Sagrada Familia in about 25 minutes. En route, you’ll see many Modernist masterpieces and soak up the unparalleled vibe of the Dreta de l’Eixample area.

If you want to save time, hop on the metro. Take Line 5 (blue) from Diagonal metro station and get off at Sagrada Família. The church is right outside the exit.

You can also take the hop-on hop-off tourist bus, which has a stop directly in front.

💡 Tip: It’s no longer possible to buy your Sagrada Familia ticket in person. The only way to enter Barcelona’s most famous attraction is to get your ticket online!

🕒 Time needed: 2 to 2.5 hours. Budget time for going inside, climbing the towers, walking around the basilica, and taking photos from the surrounding parks.

4. Marvel at Recinte Modernista de Sant Pau

After visiting Sagrada Familia, take a short walk up Avinguda de Gaudí, a lovely, pedestrian-friendly street lined with cafés and restaurants.

It connects two architectural gems, Sagrada Familia at one end and the Recinte Modernista de Sant Pau at the other.

🍴 The walk takes about 15 minutes. The avenue is a great spot to have lunch, coffee, or ice cream. 😉 The further you walk from Sagrada Familia, the more authentic the eateries feel. The area is perfect for a relaxed midday break before continuing your one day in Barcelona.

The former hospital complex is one of the most beautiful and underrated spots in Barcelona. Designed by Lluís Domènech i Montaner, it’s a stunning example of Catalan Modernism, with colorful tile work, stained glass, and lush gardens.

You can explore the outside for free or buy a ticket to see the restored pavilions inside. I highly recommend going inside. In my humble opinion, this is the most beautiful building in Barcelona, a city known for its stunning architecture. 😍

🕒 Time needed: 2.5 to 3.5 hours. Enough time to walk Avinguda de Gaudí, have lunch, and visit one of the best UNESCO sites in Barcelona without rushing.

5. Finish with a Hidden Gem

End your day at one of the best viewpoints in Barcelona, Los Bunkers del Carmel.

The Civil War relics sit on top of Turó de la Rovira and offer sweeping, 360-degree views of the entire city. It’s a favorite spot for locals to watch the sunset, and a peaceful way to take in everything you’ve seen.

Try to time your visit for golden hour. The light is amazing, and it’s the perfect way to end your one day in Barcelona.

From the Recinte Modernista de Sant Pau, you can walk up to the Bunkers in about 30–40 minutes. It’s uphill, but the views are worth the effort.

If you’d rather save your energy, take Bus #V23, then walk the last stretch up the hill. To return to Plaça Catalunya, take Bus #24, which will bring you straight back to the city center.

🕒 Time needed: 1.5 hours. Includes getting there, climbing up, enjoying the views, and resting a bit before heading back down.

Bonus: Explore the Gothic Quarter

If you still have some energy left or decide to skip the Bunkers, take a stroll through the Gothic Quarter before dinner.

The maze of narrow streets, medieval buildings, and hidden squares feels like a different world. You’ll find centuries-old churches, Roman walls, and quiet corners just a few steps from the city’s busiest areas.

It’s a great place to slow down and soak in the atmosphere after a packed day. Wander through Plaça del Rei, stop by the Barcelona Cathedral, or simply get lost in the alleyways. You’ll always stumble across something interesting in the oldest part of the city.

🍴 For dinner, I recommend Bodega La Palma, a cozy, old-school spot tucked into a quiet corner of the Gothic Quarter. It’s known for its scrumptious traditional Catalan dishes, seasonal tapas, and friendly service.

It’s the kind of place where locals eat, and a great way to end your 24 hours in Barcelona.

🕒 Time needed: 2.5 to 3 hours. Perfect for a relaxed evening walk and dinner at a local restaurant.

Top Tips for Exploring Barcelona in 24 Hours

💡 Book tickets online in advance. Big sights like Sagrada Familia often sell out, and even the hop-on hop-off tourist bus is easier (and sometimes cheaper) to book ahead.

💡 Wear comfortable shoes. You’ll be walking a lot, even if you use public transport, so good footwear makes a huge difference. I had to help a friend once buy sandals because her sneakers were killing her feet after walking 30,000 steps on her first day in Barcelona…

💡 Stay hydrated and bring a snack. Especially if you’re planning to walk up to the Bunkers del Carmel, pack a small snack and a drink. There are no shops or cafés at the top.

💡 Use public transportation. The metro is fast and easy to navigate. And if you want to see more without walking too much, the hop-on hop-off bus is a great option.

💡 Eat earlier (or later) than the locals. Restaurants get busy around 2 PM for lunch and 9 PM for dinner. Showing up before or after the rush means shorter waits and quieter tables. Especially if you don’t have a reservation, it might be impossible to find a table when it gets busy.

💡 Beware of pickpockets. Barcelona is a safe city, but it’s notorious for the “skillful” pickpockets. Especially in crowded areas in the city center and in the metro (L1, the red line, is the worst…), you have to be extra careful with your belongings and surroundings.
