Regional Natural Park of the Ligurian Alps

Situated just a short distance from the Mediterranean Sea, Ligurian Alps Regional Natural Park is nestled within the Ligurian Alps, the southwesternmost part of the Alps, in northwestern Italy. There are 88 named mountains in the Ligurian Alps Regional Natural Park, the highest of which is Monte Saccarello (2,200 m/7,217 ft), which lies along the border between Italy and France.

Ligurian Alps Regional Natural Park, Italy


Ligurian Alps Regional Natural Park was established in 2007. It is located in the province of Imperia in the Italian region of Liguria. It is situated between the French border and lower Piedmont. The park stretches across the municipalities of Rocchetta Nervina, Rezzo, Triora, Pigna, Mendatica, Montegrosso Pian Latte, and Cosio d’Arroscia.

The park covers 60 sq. km (23 sq. mi) of protected area and is located across three valleys:

  • Nervia Stream Valley – Closest to the Mediterranean Sea and has a more mediterranean environment
  • Upper Argentina Valley – Located in the municipality of Triora and features steeper slopes and rocky terrain
  • Upper Arroscia Valley – Characterized by vast pastures and woodland

Ligurian Alps Regional Natural Park is home to Liguria’s highest mountain, Monte Saccarello (2,220 m/7,217 ft), as well as the region’s deepest cave—Grotta della Melosa.

Ligurian Alps Regional Natural Park, Italy


As part of the Ligurian Alps, Ligurian Alps Regional Natural Park encompasse an area that was formed by ancient sediments around 200 million years ago.

The land emerged around 38 million years ago and has been formed and shaped by water over millions of years into what we see today: dolomitic walls, karst plateaus, rugged hills, overhanging walls, and an underground network of caves and cavities.

Ligurian Alps Regional Natural Park is made up of helminthic flyschs from the Maritime Alps, which alternate with layers of stratified sedimentary rocks such as shale, sandstone, marly limestone, and dolomitic limestone. Within the park, you will find sub-vertical walls, gorges, and surface karsts.

Due to the nature of the rock formations, the area is very popular with rock climbers who can enjoy the various peaks of Val Nervia, the Loreto Gorge, and the walls of Piancavallo. The Piancavallo area is actually a very important karst area in Europe, mostly due to its extensive number of underground caves.

An interesting example of a deep karst formation is the incision gorge in Gola delle Fascette, which is around 600 m (1,968 ft) long. The gorge follows the Tanarello and Negrone streams. As the valley becomes more narrow towards Upega, the Gola delle Fascette swallows the water into its natural cavities, underground water pipes, and swallow holes, returning it further downstream from secondary springs and caves.

Other interesting underground karst forms include the Grotta della Melosa, which is approximately 1,650 m (5,413 ft) long and 253 m (830 ft) deep, making it the deepest cave in Liguria.

Interesting examples of surface karst forms and developed sub-vertical walls can be found at the cliffs of Loreto and Realdo, as well as gorges on the Monte SaccarelloMonte FrontèMonte Monega.


The Ligurian Alps Regional Natural Park is home to a huge variety of plants. In fact, it contains several endemic species, thanks to its location between typical Mediterranean and Alpine climates.

This biodiversity is largely due to the geographical position of the park, as well as the region’s geology, soils, and climate, all of which have led the area to be considered one of Europe’s botanical paradises. Indeed, an estimated 3,000 plant species have been recorded in the territory to date.

Home to a landscape of interesting contrasts, the Ligurian Alps Regional Natural Park hosts a mix of Alpine and Mediterranean environments, due to its location close to the Mediterranean Sea.

Here, hikers will find purple saxifrage, which is more often found in the high Arctic and high mountainous areas, yet here overlooks the sea, not far from plants such as thyme, cacti, and prickly pears.

Similarly, in the park, Mediterranean orchids grow close to Ligurian gentian. The best time to visit is arguably during the spring, when the flowers start to bloom and the slopes of Monte Saccerello are covered in rhododendrons.

The area is also home to alpine meadows, mixed woodland, larches, white fir, Scots pine, and beech, which grow just a few kilometers from Mediterranean scrub. Some of the endemic species in the region include callus saxifrage, dusty primrose, bow lily, and Bicknell rhapontic.

Birders in the Ligurian Alps Regional Natural Park can also watch out for black woodpeckers, eagle owls, golden eagles, ptarmigans, and ravens, among other species.

Mammals in the Ligurian Alps Regional Natural Park include the ermine, Alpine hare, pine marten, chamois, and snow vole. Wolves and wild cats are also known to travel in the woods and along the ridges in the park, but they aren’t so easy to spot.

Thanks to the numerous caves and grottos in the Ligurian Alps Nature Park, there are also several species of bats that you might get to see if you’re particularly lucky during your visit.

Human history

Ligurian Alps Regional Natural Park demonstrates centuries of human history through the shape of its land and its many villages. Within the park, you can find churches, stone bridges and huts, as well as museums that highlight the traditions of the people that populated this area throughout the centuries.

Prehistoric remains have been uncovered in Rezzo and Realdo, as well as the old forts of Cima Marta, dry stone walls. Villages dot the landscape, carrying their stories into the modern day.

Small medieval village of Pigna, Liguria

The chestnut trade has long been an important industry in the Ligurian Alps. In fact, the history of it is told in a museum in Montegrosso Pian Latte.

Triora is also in the history books due to a witch trial that took place in 1587–89, which ended in the death of about 200 women living in the area. The village is also known as the Borgo delle Streghe or “Village of Witches.” It is worth a visit, if not for it’s spooky history then because it’s a member of the borghi più belli d’Italia, which are also called the most beautiful villages in Italy.

There are also plenty of other shorter hikes in the park that are great for a day trip or short overnight adventure.

Il Sentiero Degli Alpini (Alpine Trail)

The Alpine Trail (Il Sentiero Degli Alpini) lies on the boundary of Italy and France. It is carved into the slopes of Monte Pietravecchia and Monte Toraggio.

The route was constructed by Italian soldiers between 1936 and 1938. It was originally created as a safe route to transport soldiers, armaments, and provisions from the Monte Grai barracks and later from the Muratone Pass to the Cima Marta fortifications.

The route is recommended for experienced hikers with a head for heights. Part of the original, longer path after Gola dell’Incisa (which is located along the border with France) is now closed on the Italian side due to landslides, so it is forbidden to walk here. Hikers can also join part of the Ligurian High Route from here.
