Running just alongside the campsite and with direct access is the Via Verde de Ojos Negros. This is an old disused mineral railway, part of a much longer cycle/walking track which runs from Sagunto to Teruel.
Although I was not feeling 100% with a cold and cough, at least the cycle track would be fairly level. It was a beautiful day, so we packed our lunch and set off.
We passed the old Navajas station, which was quite a distance from the town.

We soon came to the reservoir, the Pantano de Regajo. We spoke to a couple on the campsite who said they had wild camped here a few years ago.[
We went through 2 tunnels which were quite long but lit, then went over a viaduct, through a cutting and reached an old station for the next town Jerica.
We were passed by a pelaton of Spanish bikers all in multi-coloured lycra.  
We passed a group of walkers and then as we approached Jerica there was another old station which had been turned into an Interpretation Centre ( the Spanish are very fond of these!) for the Via Verde.  Unfortunately it was closed, but opposite was a lovely picnic spot with views across to the town of Jerica.
We stopped here for a leisurely lunch and then made our way back to the campsite.

Camping Altomira offers 1 hour per day free wifi in the cafeteria or TV room/ salon.  The cafeteria shuts at 4pm and the salon is a large unheated room, which is often locked in the evening. This means sitting outside in the cold to get wifi!   Wifi on the pitch is expensive and very unreliable - hence the absence of photos on the blog until now!
We have had 2 lovely sunny days, but as we are up in the hills the evenings and early mornings are quite cold and it takes a while to warm up.
