The Apennine of Umbria and Marche, north
This is the part of central Apennine that I am able to inlcude, for the time being. I roamed most parts of the Apennine, but with several areas I still do not have the sufficient familiarity that allows me to find myself at a glance.
As usually, first come the cornerstones of this area, with reference to the Apennine divide ridge: to the north, the Bocca Trabaria pass and to the south, the Colfiorito pass. On the Adriatic sea side, these borders include the territory from the Metauro river right bank, getting to the sea at Pesaro, to the left bank of river Chienti, ending into the Adriatic sea at Civitanova Marche. On the Thyrrenian side is still river Tevere valley, with some secondary tributaries, at the beginning; then there are the two valleys of rivers Chiascio and Topino, with a characteristic N-S direction , in their upper parts, so almost parallel to river Tevere. River Topino then abruptly turns W-NW, west, just south of Foligno, flowing into the Chiascio and then, together, into the Tevere, between Assisi and Perugia.
To the west, river Tevere represents the border of this area. To the south, a conventional limit can be set by the line Perugia – Assisi – Foligno – Tolentino – Civitanova Marche. South of this limit it is already the territory of Valnerina, the river Nera valley.
With respect to the area laying north of it, ending with Montefeltro, the landscape here has some drastic changes. We enter into the area of limestone mountains, characterising the major part of central and southern Apennine, to the doors of the Calabria region. The lanscape features that here start to appear are the karst plateaux, the organisation of mountains in blocks with deep canyons between them and the famous caves. For a better illustration, but also because of some differences that a trained eye starts to perceive, I divide this territory in two areas: the one going until to Fossato di Vico pass, embracing the first three mountain groups of mounts Nerone, Catria and Cucco; and the one south of it, going to the Colfiorito pass, including, amoung the others, the range of Gualdo Tadino, mount san Vicino, mount Pennino and mount Subasio, the latter just ovelooking the city of Assisi.
The first limestone rock groups, the first inland plateaux, the first great central Apennine canyons. Dark birch forests contrasting with the yellowish top meadows during summer: a taste of a lanscape type that will accompany down to the southern Apennine. The three mountains perhaps more besieged by mountain roads, among all but, despite this, still with great hiking possibilities.
Another still relatively low mountain area, but more and more similar to the great ranges of central Italy. Lesser known old centres from which is possible to start hikes with great quote differences, with views on the Sibillini range, here already at short distance. Lesser known valleys and tops, and historical places, like Assisi and many other centres of the Marche and Umbria regions.
