This bivouac shelter is a very unique construction, basically composed of a room with a door, windows, and a cistern to collect rainwater, with a manual pump for its extraction. It should be remembered that this is, therefore, water without any sanitary treatment. It is especially important to be respectful in the use of these shelters, whose maintenance and good condition are basic for shepherds in an area as isolated as this. If you walk the marked trail Bosques del Sur, you will find it at kilometer 11.4 of stage number 15.

Last year in August (2024) it was brimming with energy and enthusiasm, but this year (2025) it's dry again. There's water, but it doesn't even fill half the pool. The water filters a few meters down, into Fuente Segura de Abajo.

The pine tree is estimated to be around 500 years old and about 40 meters tall. From the trail, it doesn't look so large, but as you get closer (now via some stairs made of logs), you realize its true size.
