I'll try to sum up my "Spanish day tripping reports" with spot mapped pics
Canencia Pass http://goo.gl/maps/LpjK3
Surrounded by trees like this ones. I don't have a good pic of the road. Is narrow and very twisted
Entrepeñas Dam http://goo.gl/maps/m2WEr
Is a very worn paved road.
Mijares Pass http://goo.gl/maps/BZGO5
Another worn road, twisted to the limit, very funny! Those 3 pieces of road you see, are the same road
El Pico Pass http://goo.gl/maps/U4aai
Good paved, very twisted road.
All the above pictures were mine.
Now I'll mark some spots that I know but don't have pics. I'll try to get 'em from the web...
El Burguillo Dam http://goo.gl/maps/Rk0MU
Beautiful road, you have access to the dam via non-paved roads
Going into Navaluenga town, you have to your left the "Pit Lane" bar, bikers friendly!
You can take there a fried egg, fries and a piece of bread, plus your drink, for 2.50 €
Puebla de la Sierra Pass http://goo.gl/maps/nLIsm
No delimiter marks on the road, so you can ride from apex to apex as long as you don't see any vehicle coming
There's a great landscape from above.
The landscapes here around Madrid aren't as good as in the Alps, but on this roads you will find loads of bikers going and coming (only if sunny
I tried my best with my English, I hope it was enough.
And I hope this info is useful to you!
