Top Things to Do and See in Spain

Spain packs Roman ruins, Moorish palaces, Gothic cathedrals and some of the world's most daring modern architecture into a single country. These are the experiences worth building a trip around, grouped by area so you can plan a realistic route rather than zigzagging across the map.

Madrid and its day trips

• The Prado Museum: Velázquez, Goya, El Greco and Bosch in one of the world's great art collections. Give it at least half a day, then unwind in the nearby Retiro Park.
• Toledo or Segovia: both are roughly half an hour from Madrid by high-speed train. Toledo is a hilltop maze of churches, synagogues and former mosques, while Segovia has a towering Roman aqueduct and a fairy-tale Alcázar.

Barcelona

• The Sagrada Família: Gaudí's still-unfinished basilica, at its most astonishing inside when coloured light floods through the stained glass. Book a timed entry well ahead.
• Park Güell and the Gothic Quarter: mosaic terraces and city views in the morning, then medieval lanes, hidden squares and the cathedral in the afternoon. Casa Batlló and La Pedrera add more Gaudí if you are hooked.

Andalusia

• The Alhambra in Granada: a palace-fortress of carved stucco, tiled courtyards and the Generalife gardens. Tickets regularly sell out weeks ahead in busy months.
• Seville's Real Alcázar and cathedral: the royal palace's gardens and patios are a highlight on their own, and inside the cathedral you can climb the Giralda tower by a series of ramps rather than stairs.
• The Mezquita of Córdoba: a vast former mosque with a forest of red-and-white striped arches and a cathedral built into its centre.
• Flamenco: see a performance in Seville or Granada. A small venue (tablao) gives you a far more intimate show than a big dinner-and-dance package.

The north

• The Guggenheim Museum Bilbao: Frank Gehry's titanium-clad building is as much the attraction as the modern art inside. Combine it with an evening hopping between pintxos bars in San Sebastián's old town, a short trip along the coast.

The islands

• Teide National Park, Tenerife: a lunar landscape around Spain's highest peak, with a cable car that climbs high up the volcano. On clear days the views stretch across the Atlantic to neighbouring islands.

Mallorca, Menorca and Ibiza are known for beaches, but Mallorca's Serra de Tramuntana mountains and Palma's sea-facing cathedral are worth a day away from the sand. Domestic flights and ferries connect the islands with the mainland.

Booking tips

• Book the Alhambra, the Sagrada Família and the Real Alcázar through their official websites as early as you can. In spring and summer, the best time slots disappear fast.
• Some tickets carry your name, so bring the passport or ID you booked with.
• Be wary of resale sites charging well over the official price, and stick to official or authorised sellers.
• Several big museums offer free entry at set times. These periods are popular, so check the official site and expect a queue.
• Visit headline sights first thing or late in the day, and check closing days, since many smaller museums shut one day a week, often Monday.
• Save your ticket QR codes in your phone's wallet or take a screenshot as a backup.

Stay connected in Spain

Most major sights now scan mobile tickets at the door, so a reliable data connection at the entrance saves a lot of stress, and it also helps with audio guides, last-minute schedule changes and maps between monuments. HelloSIM eSIMs are data-only plans that you install before travelling; the line connects when you reach Spain, while your own SIM stays in place for calls. Heading on to Portugal, France or beyond? A regional plan keeps one eSIM working across borders.
