The next day was a circular walk to the chapel of Peninha
As the book said there are stunning views over the area and as far as Lisbon, we had uncertain weather but it was still clear. Unfortunately the chapel isn't open for visitors so we had to look through the windows. We copped out of the walk around the top and instead walked back down (though a different route). Dinner was at the hotel, we weren't wildly keen but it was very atmospheric!
