You can explore Cervantes Park by walking up from Av. Diagonal, where the main entrance is, or down from the Ronda de Dalt for a more relaxed stroll. This large green space is much appreciated by walkers and athletes for its wide paths and sunny and shady spots. But if anything, it's known for its rose garden. From the beginning of spring through autumn, more than 10,000 roses fill 4 hectares of one area of the park. And in early May, the garden hosts Barcelona's International New Rose Competition.
