Parc de Garraf

Garraf Natural Park is one of the largest protected areas near Barcelona, spreading across more than 12,000 hectares of limestone, karst terrain and touching nine municipalities, including Olivella, Sitges, Begues, Castelldefels, Gavà and Vilanova i la Geltrú. Olivella hosts one of the park's information points, right in the town centre, making it a convenient starting place for planning a visit.

What does the landscape look like?

Garraf is a rugged, hilly area cut by ravines and rocky ridges, formed mainly of limestone. This geology has produced extensive karst features — caves, sinkholes and underground water channels typical of limestone terrain shaped by water erosion over long periods. The vegetation is classically Mediterranean and adapted to dry, rocky soil: low scrubland (garriga), dwarf fan palm, holm oak groves, Aleppo pine woods and tough, drought-resistant shrubs. The climate follows the usual Mediterranean pattern, with heavy rainfall in spring and autumn, mild winters and hot, dry summers.

How is the park managed?

Garraf belongs to the network of natural parks protected, promoted and managed by the Barcelona Provincial Council (Diputació de Barcelona), through its department for natural areas and green infrastructure. This body maintains the trail network, signage and visitor infrastructure across the park, which is administratively and functionally linked to the neighbouring protected areas of Olèrdola and Foix.

What can visitors do here?

Hiking and cycling are the main ways to explore Garraf. The provincial council maintains more than ten marked routes of varying difficulty, running through ravines, hills and viewpoints that open onto the Mediterranean coastline. For a first visit, Olivella is a practical entry point: its information centre can advise on route choice, difficulty level and current trail conditions before heading out.

Why start a visit in Olivella?

Olivella sits at the heart of the park and functions as one of its main gateways. The information centre located in the town square helps visitors get their bearings in an extensive trail network before setting off — useful given the park's size and the variety of terrain it covers, from coastal cliffs to inland ridges.
