The route starts from the outskirts of Montalbán, at kilometer 167.4, on N-211 toward Teruel. We will take the "old" Utrillas way, toward the fertile lowlands of the Martín river and of the Muela massif, south of Montalbán. At the split, some 400 meters from the road, we will take the left fork to the Martín river; this path is lined with poplar trees.
Soon after crossing the river, we will leave the Utrillas way and take a small and slightly uphill path through fields. This will lead us to a wood and forest path . This path will lead us to the Valdemiguel spring, and upwards, to the Muela massif. It is also possible to reach this point by car, by following the Utrillas way from the river and through the forest.
From the Valdemiguel spring, at the foot of the Muela, a winding old horseshoe path leads us to a lookout. There we will find an information board with the area's geological details, and we will enjoy an impressive view of the valley and village. The path continues uphill through rocky passages, which require extreme caution.
Without leaving the path, we will get to some old watering places in the Vaciones spring. At the top of the Muela, the trail levels out and leads to a fork. One side leads a 5 minute tour to the Montalbán lookout (1,210 m. above sea level), where an information board identifies surrounding mountains, villages and valleys. The other path, also 5 minutes journey, brings us closer to a cave-the Cueva del Greñicas (1,225 m. above sea level). From both of these vantage points, we will have the possibility to observe vultures and other birds of prey landing.
From the split in the path, and at the top of the slope where the Vaciones spring is located, we will find an old path running through the top of the Muela. The marking of the path is being accomplished in the years 2004-2005 thanks to the Cultural park of the Martín river. From the spring we can opt for walking back down the same path, or for continuing through the Muela to Morrón Royo. There, a downhill trail to the forest path will return us to the Val de Miguel spring, and then to Montalbán.
