Iconic Buen Retiro Park, known locally as Parque del Buen Retiro or El Retiro, is Madrid's green heart between Puerta de Alcalá, Paseo del Prado, and the museum district. Wander from the rowing lake to Palacio de Cristal, past rose gardens, puppet shows, and shaded paths with more than 15,000 trees.
For a first visit, choose a guided walking tour to connect the lake, pavilions, and quieter gardens without missing the stories.
