Piana di Veglia, where the centuries-old presence of man and the traditions of the rural culture harmoniously coexist, is the ideal place to discover the geological, morphological, botanical, and wildlife features of the Alpe.
The tour of the basin, a short and easy itinerary, can be considered a complete summary of the different aspects and specific features of the Park. As a matter of fact, the homonymous "Sentiero Natura" (Nature Trail) leads us through different laps: the glacial evolution of the basin, the "Marmitte dei Giganti" (giant kettles or potholes), the ancient hunters of Alpe Veglia, the red ant, the mineral spring of Rio Mottiscia, the larch, the pasture, the lime-kiln, the lichens, and the great Alpine folding. The main nuclei and the most picturesque patches of the plain are Cianciavero, Aione, Ponte, Cornù, La Balma, "Lago delle Streghe", and Frua waterfall.
Along the trail following the right bank of Rio Frua, after crossing the watercourse on a small bridge, you reach the beautiful plateau called "Pian dul Scric" (1,993m above sea-level): it is one of the main summer pastures for cows, but it is also a plateau of rare beauty scattered with huge erratic blocks. Valtendra Pass, almost a rocky passage, is the last place where Mt. Leone dominates, since it will soon give way to the mountains of Devero. From here you can go down for a short stretch to Bondolero valley, characterized by two beautiful rocky plates; you can also reach in a short time an oblong lake - where it is possible to see the Alpine newts - from which you can go ahead towards Scatta d'Orogna.
The huge and fascinating Buscagna valley is one of the characteristic alpine environments of the Park ideal as the habitat of the wildlife. In its huge subalpine grasslands, stretches of rhododendron and bilberries, larch woodlands which in the autumn take on wonderful colors, it is possible to find wild goats, chamoises, marmots, hares, ermines, black grouses, Alpine newts, common frogs, Tengmalm's owls, common owls, and a number of bird species nesting here.
Devero or Codelago Lake: the homonymous dam - one of the first ones ever built - was built between 1908 and 1912. It represented an impressive enterprise which provided the first hired job opportunities for the local population; nowadays it is the main destination point of hikes thanks to its beautiful places and the comfortable trail leading to it.
The "great East side" of Devero from Alpe Fontane to the Forni has landscapes reminding of Canada: small lakes and peatbogs, summer pastures, grasslands, and open landscapes offer great views to hikers.
