Parc Güell

A magical city park designed by Gaudí

Word to the wise: The park also includes the Gaudí House Museum, where the great man lived for 20 odd years and which showcases some characteristically unique objects and pieces of furniture.
Gaudí didn't limit his imagination to buildings. Another of his UNESCO listed creations is this park atop a hill in the Gràcia district: a colourful and exciting maze of gardens, pavilions and towers.

Delights can be found around every corner but amongst the highlights are the dragon fountain, the fairy-tale pavilions and the Plaza de la Nature square, which is dotted with beautiful mosaic benches. The park is pretty big, so plan to spend half a day here to properly explore.
Don't leave before taking in the stunning views of the Mediterranean Sea from the Gran Placa Circular. Here you'll also find the world's longest bench, a colourful, serpentine creation designed by Gaudí's creative partner Jujol.
