You. Guys. I went to Portugal – Sintra specifically – and I loved the town so much that I went back and explored on my own. I had seen photos of Pena Palace in Sintra, and I just knew that I had to take a day to travel back to see the town and the castle. It’s gorgeous! With its colorful exterior, fabulous tilework, and beautiful views, I would say it is a must see if you are in Sintra or anywhere close to Lisbon.
