4. Visit the Golden Triangle of Art
There are three major art galleries in Madrid within a 10-minute walk from each other, and guides will tell you that they’re all a must-visit. But realistically, hitting up the Prado, the Reina Sofia and the Thyssen-Bornemisza in a single visit is pretty impossible—so pick the one which best suits your art interests. If it’s old-school Velazquez, El Greco and Goya you’re after, the Prado’s for you. If Spanish art means Picasso and Dalí to you—and you feel the need to be overwhelmed by Picasso’s enormous, legendary “Guernica,” then the Reina Sofia is where you need to be. Want something in between? The privately-owned ThyssenBornemisza fills in the gaps, and tends to be a lot less crowded.
