The Route of the Farms begins at Malveira da Serra, following the southern slope of Serra de Sintra, marked by the eruptive massif, an intrusive structure in the limestone and calcareous schist series dating back to the Jurassic and Cretaceous periods. Here, the ancient sedimentary formations have been eroded away and, today, the syenite core is surrounded by uncovered granites.It is on this ring of granites that Malveira da Serra is located, the starting point of the Route of the Farms, a route that runs along the slope of this mountain range, an area integrated in the National Network of Protected Areas, classified as a Natural Park and included in the Sintra - Cascais site, under the Natura 2000 Network.
