Begin your day in Madrid by exploring two of its most famous spots. Puerta del Sol is the heart of the city and a great place to start your journey. It is home to a military clock, which locals use to make their New Year's Eve countdown. A small walk from Puerta lies Plaza Mayor, which was once used for bullfighting, coronations, and even executions. The plaza is now a popular spot for people to dine in excellent restaurants and enjoy street performances.
The Prado Museum is a must-visit for all art lovers. The museum holds one of the world's most significant collections of European art, including works from some of Spain's most famous artists such as Goya and Velázquez. After viewing the art, make your way over to Madrid's oldest and most popular park, Retiro Park. It offers various outdoor activities ranging from boating on the lake to taking a stroll in the rose garden.
Spend Day 3 exploring Madrid's busiest street, Gran Vía, the perfect place for shopping and admiring beautiful architecture. Don't miss one of Madrid's most iconic buildings, the Telefónica building from the 1920s, and the Carrión building's stunning architecture. After exploring Gran Vía, head over to Plaza de España and visit the monument of Spanish writer Cervantes's 17th-century novel, Don Quixote and his sidekick, Sancho Panza, as well as the spectacular building that houses the Spanish Senate.
End your trip by visiting two cultural icons in Madrid, the Royal Palace, and the Temple of Debod. Explore the grand residence of Spain's monarchs and admire the stunning architecture and the beautiful gardens surrounding the palace. After visiting the palace, take a 5 minute stroll over to the Temple of Debod, a gift from the Egyptian government to Spain in appreciation for the help in saving Abu Simbel temples. The temple offers an incredible view of Madrid's sunset and a beautiful walk around Casa de Campo.
If you have more time, adding a day trip to Toledo or Segovia is a great option. Toledo is a medieval city and UNESCO World Heritage site known for its stunning architecture, while Segovia is equally remarkable and well-known for its Roman aqueduct and fairytale castle. Alternatively, if you have less time, consider visiting only the Prado Museum, Retiro Park, and Gran Via to get a flavor of Madrid's traditions and history.
