Portugal was a little unexpected addition to the road trip and proved that it's a good idea to go with the flow and leave some travel space open and unplanned.  It was perfect timing for us to have a week of freedom to drive around and explore a new country, just leaving it up to chance. We hoofed it through the mossy hills of Sintra along roads that had a colorful castle on one side and the jungle on the other and we enjoyed a few unexpected beach days along the cliffs of the sleepy surf town Sagres. We followed less of the guidebook and GPS and more just listened to where the land took us.
