Fail 8 No Spain No Gain

A six days bike packing trip from Lisboa's area to Extremadura in Spain and back. Some really awesome (by luck) routing down there if you want to ride roads more than gravel. Although in all fairness parts of this trip in Spain would have been way more fun on a gravel bike. However you will find that Spain's fast roads feel extremely safe as they have large shoulders and drivers are extremely respectful. Caceres is a lovely city. The route back across the border to Portugal traverses two national parks and was a blast.
Day 4, Day 5 and Day 6, if you need! The rest is more about getting from A to B than anything else.
