Right after getting the Spyder I we went on this ride which crosses the country from North to South through a single road, the N2 (or National nš2).
We do like to call this road "our" Route 66, but it's a lot shorter (about 738km/458mi) and probably with a lot more "twisties".
We've done it on four days (at an easy pace) and it was fun!
I've made a short video which you can see it bellow:
And here's some pics (hope you won't mind, there are quite a few)
City of Chaves (starting point).
River Dam.
Palace Hote (which is also a thermal SPA)
Landscape of the Douro vineyards (from which the Port wine is made).
That's us, ready to go
The end.
