Spain is one of Europe's most rewarding travel destinations — a country of staggering diversity, from the art-nouveau boulevards of Barcelona and the palace-filled cities of Andalusia to the wild Atlantic coast of Galicia and the volcanic landscapes of the Canary Islands. Whether you're visiting for the first time or returning to discover a new corner, these are the best places to visit in Spain.
1. Barcelona
Spain's most cosmopolitan city sits on the Mediterranean coast of Catalonia, combining world-class architecture, a vibrant food scene, excellent beaches, and one of Europe's most exciting nightlife cultures. Antoni Gaudí's extraordinary works — the Sagrada Família, Park Güell, Casa Batlló, and Casa Milà — give Barcelona an architectural identity unlike any city on earth. The Gothic Quarter's medieval lanes, the buzzing La Boqueria market, and the beachfront promenade of Barceloneta complete the picture.

2. Madrid
Spain's capital sits at the geographical heart of the Iberian Peninsula, 667 meters above sea level. Madrid is a city of world-class museums (the Prado, Reina Sofía, and Thyssen-Bornemisza form one of the world's greatest museum triangles), magnificent boulevards, and a social life that starts later and ends later than anywhere else in Europe. The Retiro Park, the Royal Palace, and the tapas bars of La Latina are essential Madrid experiences.

3. Seville
Seville is the capital of Andalusia and arguably Spain's most atmospheric city — a place where flamenco was born, where the Moorish past is still visible in the extraordinary Alcázar palace complex, and where the Easter week processions (Semana Santa) are among the most intense religious spectacles in Europe. The cathedral — the world's largest Gothic cathedral — and its Giralda tower dominate the old city.
Don't miss: Real Alcázar, Seville Cathedral and Giralda, Barrio Santa Cruz, flamenco shows, Triana neighborhood
4. Granada
Granada is home to the Alhambra — one of the world's greatest surviving examples of Moorish architecture, a palace-fortress of extraordinary beauty overlooking the city from a forested hilltop. Below the Alhambra, the Albaicín neighborhood is a UNESCO-listed labyrinth of whitewashed houses and Arab tea houses. Granada is also famous for its free tapas culture — order a drink and a tapa arrives automatically.

5. Toledo
Perched dramatically on a rocky promontory above the Tagus river, Toledo is Spain's most perfectly preserved medieval city — and perhaps its most rewarding day trip from Madrid (just 30 minutes by high-speed train). Once the capital of Spain and a place where Christians, Moors, and Jews coexisted for centuries, Toledo's winding streets contain Gothic cathedrals, mosques converted to churches, and synagogues within a few hundred meters of each other.

6. Valencia
Valencia is Spain's third largest city and one of its most underrated — the birthplace of paella, home to the futuristic City of Arts and Sciences by Santiago Calatrava, and blessed with excellent beaches just minutes from the center. The Las Fallas festival in March, when elaborate papier-mâché sculptures are paraded through the streets and then ceremonially burned, is one of the world's most spectacular events.

7. The Alhambra, Granada
The Alhambra deserves its own entry — it is arguably the most visited monument in Spain and one of the most important examples of Islamic art and architecture in the world. The Nasrid Palaces, with their intricate stucco work, geometric tile patterns, and serene courtyards with water channels, are without parallel. Book tickets well in advance — daily visitor numbers are strictly limited and timed entry slots sell out weeks ahead.
8. Mallorca
The largest of the Balearic Islands, Mallorca offers extraordinary variety for a Mediterranean island — dramatic limestone cliffs and hidden coves on the north coast, the beautiful cathedral city of Palma, olive and almond groves in the agricultural interior, and turquoise beaches across the island. Mallorca has moved upmarket in recent years, with excellent hiking, cycling, and food tourism supplementing its beach holiday appeal.

9. San Sebastián (Donostia)
San Sebastián in the Basque Country has more Michelin stars per capita than almost anywhere on earth — it is simply one of the world's great food cities. The city's La Concha Bay — one of the most beautiful urban beaches in Europe — frames a charming Belle Époque city of pintxo bars, elegant seafront promenades, and an old town of extraordinary gastronomy. The Basque coast and the mountains immediately behind the city make for spectacular day trips.

10. Córdoba
Córdoba was once the largest city in Western Europe — the seat of the Caliphate of Córdoba and a center of learning, medicine, and culture during the Middle Ages. Its legacy is the Mezquita-Catedral, a building of overwhelming historical and architectural complexity: a forest of 856 columns supporting striped red-and-white arches, into which a full Gothic cathedral was constructed in the 16th century. In May, the Patio Festival transforms the city's courtyards into an extraordinary floral spectacle.
