Allow a full day to explore this beautiful and historic destination. Set on rolling hills textured by moss covered granite, the park encompasses several must-see historical sights, visitor attractions such as the Disneyland-esque Palácio de Pena, the Palácio Nacional de Sinta and the 10th-century Castelo dos Mouros. The craggy, undulating landscape constitutes the Serra de Sintra, a dramatic expanse of verdant woodland best explored on foot following the many official trails laid out for hikers and those on mountain bikes. Stunning Atlantic Ocean views await those who make it to the mountains' highest points.
