Viator Exclusive: Early Access to Museo del Prado with Reina Sofia. Hit the Prado Museum before the doors open to the public on this 6-hour Madrid tour — a Viator Exclusive available nowhere else. As one of the first to step inside on the day, you’ll see Prado works such as Velazquez’s ‘Las Meninas’ and El Greco’s ‘The Annunciation,’ without the usual crowds and hear their little-known stories from your guide. Then, ogle the 20th-century art at the Reina Sofía, including works by Picasso and Dali, as your guide explains their abstract and surrealist symbolism.
