Olivella is located in the north of the area, in the midst of El Garraf Park. This is exactly what confers on Olivella its own landscape beauty. The village comprises Olivella, several farmhouses and six housing estates.

Before arriving at the village, by the BV-2111, there is already a magnificent example of rural architecture: Can Suriol, a typical Catalan farmhouse, formed by a ´mother´ farmhouse, around which other farmhouses were gradually added. Of the initial settlement there is documentation dating to 1334. Today the farmhouse is an 18th century building which is impressive for its two exterior galleries with semi-circular arches.

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.

Through carrer Major you reach the parish church of Sant Pere i Sant Feliu, built in 1430 on the remains of the castle known as Castell Nou and restructured in the 17th century. After visiting the church, it is worth wandering through the narrow streets of Olivella before branching out to discover its surroundings.

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.

The track continues through Les Piques, an old convent in ruins, through Corral Nou and finally reaches the Palau Novella, a construction from 1892 built by the indiano Pere Domenèch i Grau with the aim of turning it into an agricultural colony. It includes various architectural styles, but its lavishness and luxury stand out. The phylloxera plague ended the fortune of the family, and was also an extremely hard economic blow for the whole area.

Today, the Palau Novella is the headquarters of the Sakya Tashi Ling Buddhist community. However, the visit to the palace is possible and interesting.

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.
