Sintra was one of my favourite parts of visiting Portugal, it was beautiful and a great break from the city of Lisbon. I spent three days checking out the city and then spent a day in Sintra. Sintra is a 40 min train ride from Lisbon and was easy to get to, looking back I wish I had at least spent the night there.
Summer home to European royalty for centuries, Sintra’s unique and fairytale castles are a must see. People usually flock here for the cooler weather and the change in the air due to the lush forests.
