Walking around the old centre of Olivella is undoubtedly a gratifying experience. Upon arrival you find plaça Major, location of the town hall and La Sala Information Centre, where you can obtain information about the El Garraf Park and Olivella in general, and from where guided tours begin to discover the most picturesque corners of the village. From this spot you can see the first settlement of the village located on the hill, Puig Molí. This settlement comprised a church, castle, and the rectory; the castle known as Castell Vell was constructed in the year 992 following a clear strategic plan during the ´Reconquest´. Today there is a mill built in the 18th century on the ruins of the castle. Very close to the Castell Vell, are the ruins of the church called Església Vella (13th century), the only example of Romanesque architecture in the area. It formed part of the old castle of Olivella and was in use until the 16th century as a parish church. From here you can enjoy a privileged view of the village, but it is difficult to reach and the path is not marked.
An excursion on foot, by bicycle or car on the track that goes from Olivella to Jafra, via La Plana Novella, will allow you to discover some of the most authentic rural landscapes of El Garraf. Leave the village via the road and after a few metres you will reach the asphalted track that leads to Can Grau and to the El Garraf Park. The path will take you to Can Grau. The farmhouse is available for short-term stays and to undertake activities to widen knowledge of the natural environment of El Garraf.
Next we pick up the path in the direction of the sea until reaching the old Barony of Jafra, now uninhabited. We return to Olivella, passing by La Fassina (where handicraft products are made with products from the Park), Els Masets, Mas Bargalló, Can Liona and Can Camps.
