Rocchetta Tanaro Natural Park: the Secret Woodland of Monferrato in Piedmont
A different Monferrato, where vineyards give way to woodland for a few hours
When we think of Monferrato in Piedmont, the first image that often comes to mind is one of vine-covered hills, small villages perched on ridgelines, castles and white country roads crossing the countryside. Yet there is a place where this landscape changes almost suddenly and woodland becomes the main feature: the Rocchetta Tanaro Natural Park, in the province of Asti.
Entering the Park means immersing yourself in one of the most valuable surviving fragments of the ancient woodland that once covered the Asti hills, an environment that helps us imagine how these lands may have looked before centuries of farming, viticulture and human intervention deeply transformed the landscape.
The Park covers about 120 hectares on the hills sloping towards the Tanaro River and is now also protected as a Special Area of Conservation within the Natura 2000 network. Its greatest value lies in its forests: here, woods of sessile oak and English oak have survived, alongside downy oak, Turkey oak, chestnut, wild cherry and many other species that create an environment very different from the cultivated hills surrounding it.
This contrast is precisely what makes Rocchetta Tanaro so interesting for walkers. In just a few steps, you can move from the agricultural landscape of Monferrato into a shady, cool environment surprisingly rich in biodiversity.
A woodland that tells us what the Asti hills once looked like
One of the most fascinating aspects of the Park is its value as a living testimony. The oak woods we see today are remnants of vegetation that once covered far larger areas of the Asti hills.
Sessile oak tends to grow mainly on ridges and drier areas, while English oak prefers cooler, more humid valley floors. Alongside them grow downy oaks, Turkey oaks, chestnuts, hazels and other species that make the woodland highly varied.
Walking slowly through it, we begin to understand how different a mature forest is from a simple area covered with trees. The plants vary in age and size, the undergrowth changes according to light and humidity, and the oldest trees develop hollows and dead wood that become shelters for insects, birds, small mammals and many other organisms.
It is precisely this complexity that is protected today. Conserving an ancient oak wood does not simply mean protecting a few large trees, but preserving an entire system of relationships between trees, soil, water, fungi and wildlife.
Oaks are the great protagonists of the Park
If we had to choose a symbolic tree for the Rocchetta Tanaro Natural Park, it would probably be the oak.
In some parts of the woodland, the oaks reach impressive sizes and form a tall, airy canopy. What is striking is not only the size of the trees, but the feeling of being inside a forest that has had the time to develop a complex structure.
Oaks are also fundamental to biodiversity. A large mature tree can become a refuge, feeding ground and breeding site for a great number of species. Even as it ages, loses a branch or develops a hollow, it continues to play an essential ecological role.
During a hike, it is worth stopping in front of these trees and observing what we usually miss when we walk too quickly: the bark, the hollows, the dead branches still attached to the trunk, the carpet of leaves and the amount of life that can be concentrated around a single tree.
In a territory strongly shaped by human activity, encountering mature trees of this kind allows us to read a much older chapter in the story of Monferrato in Piedmont.
The Park’s most famous giant, however, is not an oak
In the heart of the Park stands a tree that has almost become a local celebrity. It is the great beech tree of Val du Ge’, the Valley of Frost, affectionately known as “Emilio”, a name given to it by groups of schoolchildren.
Its presence is remarkable above all for one reason: beech is a species normally associated with mountain environments and significantly higher altitudes, whereas here it grows at around 130–140 metres above sea level, making it one of the lowest-altitude documented examples in Piedmont.
The great beech is a reminder of climatic conditions in the past and of beech forests that, after the last glacial period, were much more widespread across these hills. The cool and humid microclimate of the valley allowed this small population of beeches to survive even as the surrounding environmental conditions changed.
The best-known specimen is a true giant, estimated to be around two centuries old, with a crown measuring roughly twenty metres in diameter.
Reaching it on foot makes the encounter even more evocative, because the great tree gradually appears among the oaks and almost seems out of place within the rolling hill landscape we have crossed.
The Valley of Frost: its name already reveals a special microclimate
The Val du Ge’ area is one of the most interesting environments in the Park. Its Piedmontese name means “Valley of Frost” and immediately suggests cooler conditions than those found on the surrounding hills.
The small valley of the Ronsinaggio stream maintains a particularly cool and humid microclimate, encouraged by its shape, woodland cover and the presence of water.
Here we also find the Fonte Canà, an iron-rich spring that once represented an important local resource. Water, together with the Ronsinaggio and Rabengo streams, plays a decisive role in the biodiversity of the Park.
For a hiking guide, this is an ideal environment for showing just how much vegetation and sensory perception can change within only a few hundred metres. A short descent into a shady valley floor is enough to experience different temperatures, humidity levels, light conditions and plant species compared with the ridge above.
A small Park with surprising biodiversity
Its relatively limited size should not be underestimated. The close proximity of dry ridges, humid valley floors, streams, springs, oak woods, chestnut groves and more open areas creates a remarkable variety of habitats.
Hundreds of plant species have been recorded in the Park. In spring, the undergrowth changes completely with primroses, violets, lilies of the valley and many other flowers, while between spring and early summer several species of wild orchid can also be found.
The richness of the vegetation naturally supports a wide variety of wildlife. The woodland is home to many bird species, and the streams preserve organisms that are particularly sensitive to environmental quality.
This means that even a simple walk can become a small exercise in naturalistic observation, especially if we learn to pay attention not only to the most visible animals, but also to tracks, sounds, insects, plants and the characteristics of the waterways.
A geology born from Piedmont’s ancient sea
Rocchetta Tanaro also takes us back to the story of the sea that no longer exists, a theme we have already encountered when exploring other areas of Monferrato.
The territory of the Park developed on Pliocene sedimentary formations and includes sands linked to the ancient marine basin that covered this part of Piedmont millions of years ago. Some of these geological layers preserve fossil evidence of organisms that once lived in the ancient Po Gulf.
It is fascinating to think that woodland has grown over these ancient marine sands for thousands of years and that today we can walk among oaks and beeches while knowing that beneath our feet lies the geological memory of a completely different environment.
Once again, Monferrato in Piedmont proves that it can be read on several levels: what we see today is only the latest chapter in a story that began millions of years ago.
Easy trails, but that does not mean the whole Park is completely flat
The Rocchetta Tanaro Natural Park is particularly suitable for people who are not looking for demanding hikes.
The network of trails mainly follows forest tracks, cart roads and valley-floor paths, with generally gentle gradients. Some routes can therefore be walked at a relaxed pace and are suitable even for people who are simply used to going for walks.
However, it is more accurate to describe them as easy trails with moderate elevation changes rather than saying that the whole Park is flat. The landscape is still hilly, and some connections naturally include short climbs and descents.
This gentle variety is one of the Park’s strengths: it does not necessarily require major physical effort, but it still allows walkers to experience transitions between valley floor, hillside and ridge.
An ideal place for anyone who wants to begin walking in nature
Not everyone who joins a hike wants to cover long distances or tackle major elevation gain. Some people simply want to spend a few hours outdoors, some are approaching hiking for the first time, some prefer a relaxed pace, and others want to bring along companions who are less fit.
An environment such as Rocchetta Tanaro can be especially suitable for this kind of experience, provided that the route is chosen according to the group and the ground conditions.
The value of an outing does not necessarily depend on the number of kilometres covered. In a woodland this rich, even a relatively short route offers constant opportunities to stop, observe a large oak, recognise a flower, listen to a woodpecker or descend towards one of the streams.
When a place has so much to tell, there is no need to rush.
Walking through woodland means learning to change your pace
Among vineyards, our gaze naturally tends to widen towards the landscape. We look for villages on the ridges, the Alps on the horizon and the geometric patterns of the rows.
Inside a forest, almost the opposite happens.
Our gaze comes closer.
We begin to notice tree bark, the ground, a leaf, a fungus, a track in the mud or a movement among the branches. Sounds also become more important, because we often hear an animal long before we manage to see it.
It is a different way of experiencing Monferrato, and perhaps that is exactly why it is worth trying.
The Park is also the result of a conscious decision to protect nature
A woodland like this has not survived until today purely by chance.
The history of the area is also linked to Marquis Mario Incisa della Rocchetta, an important figure in Italian environmentalism and one of the founders of WWF Italy, who helped create the conditions for protecting this woodland heritage. The regional natural park was later officially established in 1980.
This is worth remembering because we often assume that an ancient woodland simply continues to exist on its own.
In reality, conservation requires specific decisions, monitoring, management and sometimes intervention to address invasive species or problems affecting oak health.
The forest we walk through today is therefore also the result of people who recognised its value before it was too late.
A guide is not only useful for choosing the right trail
In an apparently simple environment like this, the role of a guide may seem less necessary than in complex mountain terrain or along a technically difficult route.
But once again, the difference is not simply knowing which direction to take.
A guide can explain why sessile oak grows mainly in certain areas while English oak prefers others, why a beech tree growing just over one hundred metres above sea level is so unusual, how to notice a plant that would otherwise go unseen and how the presence of a small stream is connected to the biodiversity of the whole forest.
It means transforming a pleasant walk into an opportunity to truly understand the environment we are moving through.
This too is Monferrato in Piedmont
Perhaps the most interesting reason to visit the Rocchetta Tanaro Natural Park is its ability to change the image we have of Monferrato.
Monferrato is not only vineyards, castles, Infernot and panoramic villages.
It is also a great beech tree surviving in a cool valley at an unusual altitude, an oak woodland preserving the memory of ancient hill forests, an iron-rich spring, a small stream where environmental quality still supports delicate species, and a trail slowly disappearing into the shade of the trees.
During Monfreedom excursions, we love to tell precisely this kind of story, because truly understanding a territory means not stopping at its most famous image.
Sometimes, all we need to do is leave the vineyards behind for a few hours and walk into the woods.
And that is when we discover another face of Monferrato in Piedmont: quieter, greener and older, preserved among the trees of the Rocchetta Tanaro Natural Park.
