Take a tour from Spain, near Logroño, taking off from the nearest airport (where this plane can take off) of the Douro River source, to its estuary at Porto, Portugal.

Visit all the course of the river, including a lot of reservoirs and dams in the way, as well as cities and villages. 

This time there's no adventure component. Just watch the beautiful views. Some waypoints have no description as they are intended only to guide you through the course of the river. I hope you enjoy the Bush Trip.

No extra addons needed.

I tested all the legs and found no issues. However if you find any, please let me know.

Thanks to Buffy GC and Alexander Barthel for the great tools Biushtrip Injector and Little Navmap.
