Costa de Lisboa - Serra da Arrábida

There are pleasant excursions into the solitude of the hills in the beautiful Serra da Arrábida, now a national park, where the luxuriant vegetation includes many rare species. These include the wild olive tree, the strawberry tree, the mastic tree, holm oak, heather, lemon trees, woodbine and myrtle. The highest point is the Alto do Formosinho (501m/1,643ft), and there are fantastic views from the N 379.1 which winds through the hills.
