Description of the trekThe trek to the Lagunitas sector covers a distance of 15,3 km from the entrance of the reserve, and has an expected time of 6 hrs. The first 7 km are of vehicle road, after which the trails starts. The latter passes by the reserve guard's hut and shortly after the diversion to the Horcon de Piedra trail. At this point you must continue south heading to Altos de Cantillana plateau. The route is clearly signposted in order not to confuse the trail. In the diversion, going down a few meters, you will find a water stream where you can rest and resupply your water bottle (it is highly recommended to do so, since finding water afterwards is not assured). The trail continues with the ascent over the mountainside and the ridge of the mountain, where there is no more signalling. This is however not necessary since there is a single and well defined trail. The route ends reaching the oak forest, a beautiful place where you can camp and enjoy amazing views.There is the alternative of doing an additional section of 7 km to the Altos de Cantillana summit (marked in blue on the map). The trail advances over the plateau with a low slope, being easy to walk.
