The National Park of the Garraf lies between the lower valley
of the river Llobgegat, the Mediterranean sea and the Penedes Depression. The
greater part of the Park was declared a Natural Park in 1986. The scenery is
unusual, with rounded hilltops and deep, sheer-sided valleys. The predominant
limestone rock is dotted with a type of Mediterranean maquis and garrigue
vegetation, consisting of dwarf fan plams, kermes oak, mastic trees and the
pampas-like grass, Ampelodesmos mauritanica. Features typical of karst
landscapes include numerous caves and sinkholes, dolines, Karren, and several
underground rivers which discharge large quantities of fresh water below the
surface of the sea.
The Park itself is virtually uninhabited. The population
inside the Park is as shown:
