Cañón del Río Lobos, Senda de las Gullurías y Ermita de San Bartolomé

Source: www.naturautas.com The route begins in the parking lot of the Casa del Parque. Going up the slope you can see some apiaries that indicate that this area has a large number of interesting aromatic plants for bees. Beekeeping was an important resource. There are two types of hives: the classic ones built with logs and the modern ones, with a box appearance. Climbing up the ravine of the mill, plants capable of living on rocks appear, with almost no soil. Among them, the rompepiedras, cat grapes and pampajaritos stand out. The snouted vipers live in these stony areas, being difficult to observe them due to their elusive nature. They are poisonous and only bite if someone bothers them and corners them. To the left is a large rock known as Monica. Behind us you can see the Castle of Ucero, a historical symbol of medieval and ecclesiastical lordships. At the end of the slope there is a lime kiln that was used to obtain lime. Through the moor we can see different aromatic plants such as lavender, rosemary, thyme, sage, lavender. Looking in the distance, to the left, agricultural areas dedicated to the cultivation of barley and wheat can be seen. Three troughs are crossed. The first two are Vallejos Hondos and Las Torcas. The last one is the Barranco de las Tasugueras, in clear reference to the tasugos, the local name for the badger. At the end of the climb and after the Picachón, you reach the pass. Around the Franco hill there is a salt garden (a place where salt was left for the cattle) and a lapiaz (limestone rock dissolved by rainwater in a multitude of cracks similar to knives). From the second calera, you descend gently surrounded by junipers that begin to mix with the typical pines of the Canyon, the pudio pines. We are very close to the Canyon, deviating to the right we arrive at El mirador de las gullurías. "For San Matías the gullurías sing and the nights and days are equal" they say around here, referring to a small forest lark that in bird guides is called totovía.
