Trekking & Mountain Bike Trails in the Regional Natural Park of the Ligurian Alps

The entire area is covered by forests that evoke legends and alpine landscapes (Testa d’Alpe, Gerbonte, Rezzo beech forest), rock walls and underground cavities (Gole delle Fascette and dell’Incisa, cliffs of Realdo and Loreto, Grotta della Melosa), botanical paradises (the larch woods of Navette, rhododendrons of Monte Saccarello, the mountainous group of Toraggio-Pietravecchia), privileged observation points for wildlife (home to, among others, the golden eagle, capercaillie, black woodpecker, chamois, wildcat, and wolf). A hiker in the Ligurian Alps Park can journey back in time on the legendary Sentiero degli Alpini (Alpine Trail) or along the historic Via Marenca, on the Alta Via dei Monti Liguri (High Route of the Ligurian Mountains), and along ridge paths that offer breathtaking views of uninterrupted chains of peaks, seascapes, and medieval villages.

The territory is divided into four valleys: Valle Arroscia, Valle Argentina, Val Nervia, and Val Tanarello completes the area.

Valle Arroscia – (Cosio d’Arroscia, Mendatica, Montegrosso Pian Latte, and Rezzo)

The Upper Arroscia Valley revolves around Imperia and is the area with a prominent mountainous character, characterised by vast pastures and extensive forested areas. This valley includes Cima di Piancavallo (1896 m above sea level), with its populations of chamois, Monte Frontè (2153m above sea level), Monte Monega (1882 m above sea level), and the captivating Bosco di Rezzo. The valley extends from east to west, following the course of the Arroscia River from Monte Frontè to the Piana di Albenga. The southern exposed slope is home to villages, fields, and land cultivated with olive trees and vineyards, while the northern slopes are the realm of the “ubagu,” where shade, chestnut forests, hornbeams, holm oaks, and above 1000 metres, beeches and wild pines dominate. Between Mendatica and Montegrosso Pian Latte, the majestic Arroscia Waterfalls form a spectacular sequence of cascades, the highest of which exceeds 20 metres.

Valle Argentina –  (Triora)

The Upper Argentina Valley, with the municipality of Triora revolving around Arma di Taggia, features steeper gradients, wild natural landscapes, and settlements perched on ridges or rocky spurs. Here, the landscape immediately reveals dense forests rich in water and wildlife. The small hamlets of Realdo and Verdeggia (which still maintain their original architectural structure with narrow alleyways, thatched roofs, and wooden balconies) provide access to the areas of Monte Gerbonte (1727m above sea level), known for its natural cavities and karstic channels, and Saccarello (2200m above sea level), with its rhododendron-covered moors and extensive pastures watched over by ancient mountain huts.

Val Nervia – (Pigna and Rocchetta Nervina)

Accessible from Ventimiglia/Bordighera, it is the closest to the sea and stretches for about 20km among flower crops, olive groves, and vineyards, which, further north, give way to chestnut forests, conifers, and beech trees. From the sea to the mountains, terraced fields of olive trees and vines are replaced by thyme and lavender shrubs, and even higher up, by alpine flora. Holm oaks, maples, beeches, and firs provide shelter and refuge for chamois, wolves, and reptiles. True natural jewels of this area are the rocky environments of Mount Toraggio (1971m above sea level) and Mount Pietravecchia (2038m above sea level), in addition to the Transfrontier Reserve of Testa d’Alpe (1517m above sea level).

 Val Tanarello

Closed at the bottom by limestone walls, where the stream flows over bare rock, forming ponds and waterfalls, upstream the territory opens up, dividing into valleys covered by dense forests. We are at the border between Liguria and Piedmont (accessible from San Bernardo di Mendatica and Viozene-Upega), in an area that remains largely uninhabited and wild, a realm of beeches, pines, and rock plants. The landscape is extremely interesting from a geological perspective, thanks to the presence of outcrops, basins, and caves. A deviation at Ponte Schiarante leads to Tana Cornarea, which has yielded remains of human and animal habitation (Ursus spelaeus) from the Bronze Age. Today, numerous species of alpine fauna inhabit this area, including chamois, marmots, ermines, capercaillies, golden eagles, and black woodpeckers. For centuries a land of transhumance, the valley retains traces of stone-built settlements, old mule tracks, and medieval bridges (recommended excursion from San Bernardo di Mendatica to Ponte Tanarello).
