A Coruña is a perfect place to know Spain and the Spaniards. Although every year the number of tourists is increasing, forget about the invasions you can see in the south. Some foreigners can be seen around, usually students or cruise travellers, but most of the tourists travelling there are Spanish families avoiding the heat and the massive beaches of the south.
Although Galicia´s weather is usually rainy and cloudy, and we cannot garantee the sun as in Andalucia, summers are warm and beautiful. Lots of sunny days and good temperature to go to the beach and get tanned. There are lots of beaches in Galicia and all are different.
Going out? A Coruña has different places with different environments. To go for a coffee, for a beer, dancing, you can have anything, and if you are in the centre (Orzan Area or Plaza de Maria Pita), you can have everything. Just ask the locals.
And you can also find history there. Picasso lived and studied there, and here´s where he learned to paint. The Battle of Elviña, against the English happened there. The oldest lighthouse still on duty is the famous TORRE DE HERCULES, the symbol of the city.
