Distance: 4.5 km; Duration: 3h; Difficulty: Difficult. Location: Aldeia de Chãos Starting point: Cooperative Parking Terra Chã gps-wgs84 coordinates: 39.417998, -8.920365 The natural park of the Aire and Candeeiros mountains are the most important repository of limestone formations existing in Portugal and this is the primary reason for its classification as a Natural Park. Karst morphology, nature of the vegetation cover, the network of underground watercourses, a specific fauna, namely cave, and intense activity in the field of stone extraction are many other aspects that its classification tries to preserve and discipline. Being an altitude zone, the climate is characterized by a peculiar transition between Mediterranean and Atlantic conditions, being therefore humid, with medium temperatures and with great water shortage in summer. This route known as "From Chãos to the Alcobertas Cave" takes place in the surroundings of the village of Chãos, a small village belonging to the parish of Alcobertas and located on the southern slope of the Candeeiros mountain, on a small plateau a few meters from the top of the mountain.
