The best traffic-free bike rides around Lozoya

A very pleasant pass to climb up the Puebla de la Sierra side. To do this, you have to access it from Robledillo, with very steep ramps to warm up, and a few kilometers on a narrow and bumpy road. The views and the route are totally worth it. Avoid weekends, especially busy hours, as motorcycles, and especially cars, can spoil the party a bit, as I say, the road is very narrow. There is a fountain at the lowest point between Robledillo and Puebla, and another one when leaving Puebla de la Sierra. They are the only two points where you will be able to fill your bottles "for free".

The water of the rich of Madrid. Shade and beware of a lot of traffic on weekends

Good water and the place is beautiful. A bit crowded if you're right next to it.

Current Castle: Built in the 15th century by the Mendoza family, during the reign of John II of Castile. Historical Uses: Noble residence, defensive stronghold, and setting for events such as the imprisonment of Juana la Beltraneja.

The **Centennial Yew of Canencia** is a unique tree of great botanical and landscape value in the Sierra de Guadarrama, in the Community of Madrid. It is not just a specimen, but part of a small population of yews that has survived in an exceptional setting, the Canencia Birch Forest. ### Characteristics and Location * **Species:** *Taxus baccata* (common yew). * **Age:** The most notable specimen is estimated to be between **400 and 500 years old**. Its longevity is one of the most fascinating characteristics of this species. * **Dimensions:** It has a trunk of considerable girth (around 4.10 meters) and a wide crown about 15 meters in diameter, which demonstrates its advanced age and health. * **Location:** It is located in the **Canencia Birch Forest** area, very close to the Canencia Pass. It is often included in the popular hiking trail known as "The Birch Forest Path" or the "Mojonavalle Waterfall Path." It is located near the Sestil del Maíllo stream. * **Environment:** The yew coexists with other unique species such as birch, holly, and Scots pines. This humid and protected microclimate has allowed the survival of these trees, which are relics of colder, wetter times. ### Importance and Uniqueness * **Botanical Value:** Yews are extremely slow-growing trees and are considered almost immortal. In Spain, they are a protected species, and finding such ancient specimens is a rarity. * **Landscape Value:** The Canencia yew stands out for its majestic appearance in the midst of a very picturesque forest, attracting numerous hikers and nature lovers. * **History and legend:** Like many ancient yew trees, it is steeped in legend. In many European cultures, they were considered sacred trees for their longevity and the toxicity of their parts (except for the pulp of their fruit). ### Access and routes To visit the yew, the most common route is the **Birch Forest Path**, which starts from the Canencia Pass itself. The path is signposted. You walk along a forest track to a detour that leads directly to the Chorrera de Mojonavalle, and a little further on, you will find the yew tree. Despite its age, the tree is increasingly visible and accessible, but it is essential to be respectful and not damage its surroundings to preserve this natural monument.
