Parc de Aigües (Aigües Park)
Parc de Aigües in Barcelona's Horta/Guinardo district might be precisely what you're looking for if you're looking for a place to let your kids play, walk your dog, enjoy a picnic, or escape the heat of August. The park is well-kept, and there is plenty of evergreen and deciduous trees that can provide shade and privacy.
The park was constructed on the former Barcelona Water Company's property. It has the form of a hilly island with several terraces divided by stone walls and paths. This mountainside park is built on stone terraced, with some places dedicated to quiet contemplation and others to amusement. Three playgrounds and many small sports areas, including a pétanque court, are located inside the park. In the shade of cypress, yucca, and sweet bay trees, there are also plenty of chairs and picnic tables.
