We start this walk from the Hayedo de Montejo parking lot. And we left walking along the M-139 highway crossing the Jarama River and turning into the GR-187. Immediately we leave the road to take a track that leaves to the left in a closed way and where it indicates that we are going to start climbing.
The first section is parallel to the riverbed of the Jarama by the GR-88 – Senderos del Jarama / Camino de Riaza. And that we will leave soon to go up the New Road. Meanwhile we can enjoy the beautiful autumnal colors of the brown leaves of the oaks of the Sierra de Ayllón and the color, already with few leaves, of the beech trees of Hayedo de Montejo. But all this vision is quickly hidden from us by the intense fog that only lets us enjoy about 100 m. That, even so, we continue to enjoy.
Going up we arrive at Collado de Calahorra, where we begin to feel the cool mist hugging us, although it prevents us from enjoying the views of the Umbria de Ravinate.
We continue ascending a path through Las Serranías towards the Cerro de la Calahorra where, amidst the mist, we walk among the raised stones of its chalk, but without being able to see the views or the height of the cliffs that we are passing. We reached its peak. With its geodesic point of Santuy Pic of 1927 meters above sea level. And then we go down one of its ridges that lead us to the track and little by little we leave the layer of fog above to enjoy the sun’s rays at times.
We pass through the Mata del Riscal and continue down the Dehesa de Santuy towards the Hazas de la Ladera, almost in the small town of El Cardoso de la Sierra. We crossed it and came out on the GR-88 between some carpets of oak leaves that in areas surrounded you with those that had the trees. Beautiful!
We cross the GU-187 road and go down again along the track where we have started the walk.
We cross the Jarama, leaving behind the Sierra Norte de Guadalajara and entering the Sierra del Rincón in Madrid.
