Hola Mikel,
I did this way with my sister 2017 and you put a smile one my face with your photos
Tomorrow it will be also a walk through wonderful nature, uphill all day. But not so steep, much more steady and good to walk if you take your time. Take care for a good breakfast and in the best case a lunch package. Fortunately, there's not " so thirsty weather" in the moment, as we say in the German language.
I'll just write down some of our experiences, maybe they'll help you.
On the stage between Espinama/Fuente Dé and Portilla de la Reina is nothing, except nature. Uphill on the way to Horcada de Valcavao there will be a few places with fresh water. Downhill via Puerto de Pandetrave to Portilla there is only
one place with water, just after you entered the road and turn left. From now on, you just have to look forward to a great dinner at the hostal in Portilla, it was fantastic.
If you want to sleep the next day in the very very nice Albergue in Horcadas (a dream, great recommendation!!!) eat your Dinner in Riano, or better, buy something (also for breakfast) and cook a nice meal in the very good equipt kitchen. The Albergue is just at the entrance of the village, you can get the key at Lolly´s bar.
On your way further, when you walk through the tunnel at the end of the lake and you can already see the dam, you have to turn left (inside the tunnel). When we were there, the arrows were a little light.
The Albergue in Cistierna has everything what a pilgrim really needs, but nothing more. This hostel simply has a "bad place" between the two great Albergues in Horcadas and Gradefes, so the first impression is worse than it actually is. Inside better than outside - it´s ok.
The Albergue in Gradefes is the last house of the village, directly at the camino and is as good as Horcadas. Of course different, but also very good and very good equipt.
On your way to Mansilla or Puente de Villarente (what we did) you will not find a bar, but enough places to fill up your water
In Puente de Villarente we slept in the Albergue San Pelayo - very nice.
I wish you all the best for your way.
Buen camino Mikel
