Near Villena there are some old kilns that were used to turn gypsum into the raw material for plaster - the Hornos de Yeso - and they are near where the Villena Treasure was found.
It wasn't the most scenic spot in Alicante. There was a tip close by and lots of people seemed to have lost heart within sight of their goal and just dumped stuff by the side of the track. Nonetheless, the spot did have a certain charm and lots of lizards.
We followed a public footpath. There's a very simple system in Spain for marking paths. Red and white bands are used for long distance paths, yellow and white for shorter paths and green and white for the local stuff. The bands are usually painted on rocks, fenceposts, walls etc and they are normally well maintained. If the bands are crossed it means not to go there and a hinged symbol marks a turn.
The markings for the path we followed today were haphazard to say the best. Illusionist markers - now you see them, now you don't.
