From Sintra I got to Cabo da Roca by bus 403 towards Cascais (a one way ticket for 3,20 € ). The drive lasted 30 minutes (hardly 15 kilometres).
Cabo da Roca is the westernmost cape in Europe. Here are located a nineteenth-century lighthouse and a cross with the words 'Lius de Camoes' engraved on it,which may be translated into English as: “Where the land ends and the sea begins” . A lot of people consider Cabo de Roca to be “one of such places that you have to visit during your lifetime”. I've got to agree on that, it's a beautiful place.
Moreover, the edge of the steep and rocky Cabo da Roca is elevated 144 metres above ocean level. It is another place which attracts thousands of tourists every year. Truly romantic scenery!
That's why if the weather is fine it's worth taking photos of Cabo de Roca. Sadly, the weather wasn't favorable during my stay in Cabo da Roca. Clouds covered the sky, the strong wind started to blow so I didn't have a chance to watch the sunset over the ocean. What a pity! I came back to Lisbon (through Sintra, same route).
