It was a lovely rainy day and we visited 3 different palaces. Sinatra is chock full of high end sites. Word
Of advice: go to pena Palace while you still have leg and lung strength. Otherwise you might have to take lots of breaks and catch your breath like us! Even if you go late in the day—go! It is beautiful and special. The architecture and scale is breathtaking. Nice restaurant on site as well! We enjoyed!
