Garraf Natural Park

The Park is situated to the south-west of Barcelona, approximately a half hour's drive from the city. Its limits are the lower valley of the river Llobregat, the Mediterranean sea and the Pened├ęs Depression. The Park has two different geological regions: limestone and conglomerates. The limestone scenery is spectacular, with dolines, potholes, gorges, limestone pavements and a river resurgence at the coast.

Garraf Natural Park: investigating the effects of fire on the ecosystem
Investigating the effects of fire on the ecosystem

Most of the Garraf offers a characteristic southern Mediterranean landscape. The vegetation is of African origin. Garraf is the most northerly area of Europe where this type of vegetation grows. It can be categorized as garrigue (typical Mediterranean xerophytic vegetation found on limestone) or brolla, (a variety of shrub land found on south-facing slopes).

Rural depopulation has left many farmhouses and villages in the region deserted. The area has seen a recent growth in second homes and tourism is growing in importance in the village of La Plana Novella.

The Garraf is a very important area for the manufacture of cement. Several large quarries operate cement plants, exporting to other Mediterranean countries through the ports of Garraf and Barcelona. Exhausted pits are used as land-fill sites, which have caused contamination of the ground water.

The area was declared a Natural Park in 1986, forming part of a green belt that surrounds the strongest urbanized sector in Spain.
