Spain

Base · 2–4 nights

The country’s most visually immediate city, with Gaudí, dense street life and the Mediterranean on its doorstep. See the major architecture, then spend time outside the Gothic Quarter to avoid getting a theme-park version of the city.

Base · 3 nights

For the Alcázar, cathedral, Triana and long, bar-heavy evenings—Spain at its most theatrical and social. It is a superb cultural anchor, but summer heat makes it a bad place to cram with daytime sightseeing.

Base · 2 nights

The Alhambra earns every superlative, but Granada works because the Albaicín, steep streets and tapas bars make the city feel intimate rather than monumental. Stay long enough to see the palace without making the rest of the city an afterthought.

Base · 2–3 nights

A calmer, more livable counterweight to Barcelona: serious rice cooking, a huge converted river park, modern architecture and an actual urban beach. It fits best as a two- or three-night break between Madrid and Barcelona.

Short stop · 1 night

Come for the Mezquita-Cathedral, one of Europe’s essential buildings, and stay overnight so you can see it before the day-trippers take over. It is compact enough for one night but too good for a rushed transit stop.

Base · 6–7 nights

Bilbao and San Sebastián pair art and design with Spain’s most serious pintxos culture, surf beaches and a green Atlantic setting. It is a better summer choice than inland Andalusia, but expect rain and San Sebastián prices.

Atlantic, granite and seafood-heavy, Galicia feels markedly separate from Mediterranean Spain. Base around Santiago de Compostela and the Rías Baixas; rent a car if you want the coast, wineries and smaller towns to make sense.

Base · 4–5 nights

This is Spain for hikers, cider drinkers and people who want sea cliffs and the Picos de Europa instead of another cathedral circuit. A car matters here far more than it does in the major cities.

Base · 2 nights

Use Málaga for its easy airport access, museums and food; choose Cádiz for the stronger old-town character, Atlantic wind and seafood. Pick a specific town rather than blindly booking the Costa del Sol, where resort sprawl is a real trade-off.

Mallorca combines Palma, mountain roads and coves; Menorca is quieter, while Ibiza can be either nightlife-heavy or surprisingly rural. Treat the islands as a beach-focused trip, not an add-on to a rushed mainland itinerary.

Volcanic, Atlantic and reliably warm when mainland Spain is cold: Tenerife offers the broadest mix, Lanzarote the starkest landscapes, and Fuerteventura the best wind-and-beach focus. This is winter-sun Spain, not a compact dose of historic mainland Spain.
