The Cerros Margosos de Pastrana y Yebra Microreserve is a protected natural area of terrestrial character, declared in 2002 and with an approximate area of 68.47 hectares. It is located between the municipalities of Pastrana and Yebra, in the province of Guadalajara, in the surroundings of the confluence of the Arlés river and the Val stream with the Tajo river. Its main interest comes from a very specific geological substratum, formed by limestone, gypsiferous marl, gypsum and clay, which conditions a landscape of dry hills and soft materials easily eroded. The most valuable thing to be seen here is the specialized vegetation that has managed to adapt to these marly-gypsiferous and saline soils, a rare and very fragile habitat. Particularly noteworthy is the presence of Limonium erectum, an endemic species with a worldwide distribution restricted to this enclave, as well as other species of botanical interest such as Gypsophila bermejoi, Lepidium cardamine and the orchid Ophrys omegaifera subsp. dyris. For this reason, the route is of interest to both naturalists and visitors looking for discreet but scientifically unique landscapes. Its relevance is above all botanical and conservationist: it protects very well represented halophilic and gypsiferous communities and safeguards endangered species included in the regional catalog. The micro-reserve is part of the network of protected areas of Castilla-La Mancha and was created to conserve an enclave of great ecological rarity on the banks of the Tagus, where human pressure is low and the value of the land lies in its geological and biological uniqueness.

La Ribera del Río Arlés is a short river walk in Pastrana, in the Alcarria region of Guadalajara, associated with the stretch of the Arlés River near the town. The tourist information sheet lists it as a natural site, and the local guides present it as a walk along the riverbed with access to the riverbank and views of the river in an environment close to the town center. The interest of the resource lies in its riverside landscape: a natural corridor where water, riverside vegetation and the slopes of Alcarria articulate a simple itinerary for walking and observing the valley. According to the route disclosed by Caminos de Guadalajara, the Arlés valley is part of the environment that structures the Pastrana itinerary along this riverbed, which reinforces its value as a walk of proximity and as a reading of the local landscape. Its relevance is mainly environmental and scenic, as it complements the historical heritage of Pastrana with a natural space linked to the river. The tourist documentation of the locality places this place among the natural resources of the municipality and also mentions, downstream, La Pangía, where remains of ancient constructions such as mills and walls can be observed, which adds cultural interest to the environment if the entire valley is visited. There is no specific legal protection for this riverbank in the sources consulted, but it is recognized as a local natural resource and as a recommended section for a quiet visit, especially for those who are looking for a short walk, easy to combine with the town and with a reading of the landscape of the Alcarria.
