The Garraf Natural Park is an area of mainly limestone rock with rounded hilltops and deep valleys. There are many caves, sinkholes amd underground rivers which release their waters into the sea. The hills are dotted with dwarf fan palms which are the only species of palm trees native to Europe. The highest hill in the park is La Morella at 592 metres. The Information Centre at La Pleta is on the coastal footpath Cami de les Costes, the GR92.
