In the green heart of the Central Apennines, a stone's throw from the golden beaches of the Adriatic, in the “Gran Sasso-Laga National Park”, are the Monti Gemelli: which the poet Gabriele D'Annunzio defined in his “Notturno” (1921) "the great mountain. Cilestrina, aerial, snowy, confused with the shining clouds ... ". Of the two mountains, perfectly symmetrical when viewed from the coast, the one to the south, Monte Foltrone has always been known as "La Montagna di Campli": a multifaceted mountain, with impenetrable slopes wooded, mysterious beech woods, spectacular gorges, waterfalls, dolomite rock walls ... And to the south, just a few minutes from the charming historic center of the Farnese’s town, is the “Valley of the Squirrels”, a true outdoor paradise for trekking enthusiasts, mountaineering, climbing, biking, nordic walking, paragliding, or simply unspoiled nature lovers.
The territory of Campli extends from the beech woods and the mountain pastures of Monte Foltrone, more than 1700 meters high, in the Gran Sasso-Laga National Park, up to the Salinello valley, a few tens of kilometers from the Adriatic coast.
The municipality includes 32 hamlets ranging from Battaglia (700 m asl) to Floriano (145 m asl); within these small communities the conservation of an agricultural landscape of great historical and environmental value persists, characterized by rolling hills planted with vineyards and olive groves, cereal crops, such as the ancient solina wheat, spelled and the turquoise potato. There are numerous naturalistic peculiarities that affect the Foltrone and Monticchio mountain areas, both for the zoological aspect (the golden eagle nests here) and for the botanical aspect; over 150 endemic species of flora (orchids and glacial relics) hidden among the limestones of the ridge and in the valleys excavated in the sandstone of the neighboring areas have been counted.
