Arta Terme

Discover Arta Terme

In 1687, the physician and naturalist Giovanni Battista De Candido published the first treatise on the healing properties of the sulphurous waters flowing from the Fonte Pudia spring in the territory of Arta. That document marked the beginning of a thermal spa tradition that would define the economic identity of this Carnic centre for the following three centuries. Today, anyone wondering what to see in Arta Terme will find a town of 2,233 inhabitants set at 442 metres above sea level along the valley of the But torrent, with hamlets scattered across glacial terraces, a heritage of sacred architecture rooted in the Renaissance, and a network of trails that cross beech forests and pastures up to the foothills of the Carnic Alps.

History and origins of Arta Terme

The place name “Arta” first appears in a document from 1275, though its etymology remains debated: some scholars link it to the pre-Latin root *art-, referring to a rocky formation or an elevated point, while others associate it with the Celtic word for “stone”. Evidence of settlement in the area, however, dates back to the pre-Roman period, as suggested by finds recovered along the axis of the Val But, a natural corridor connecting the Friulian plain to the Monte Croce Carnico pass and, from there, to the Austrian side. The Romans travelled this route for both commercial and military purposes, and the presence of intermediate stations along the way is documented by sporadic finds of coins and ceramic fragments on the valley floor. Control of this transalpine road made the territory strategically important for centuries: during the Middle Ages, Carnia fell under the dominion of the Patriarchate of Aquileia, and Arta formed part of the parish system that organised the religious and civic life of the Friulian mountains.

The Parish Church of San Pietro, documented since the 13th century, served as the ecclesiastical point of reference for a vast surrounding territory. The fresco cycle preserved in the church, attributed to the workshop of Giovanni Antonio de’ Sacchis — known as Il Pordenone — or to his circle, places Arta within the circuit of Friulian Renaissance painting of the early 16th century. With the fall of the Patriarchate in 1420 and the transition to the Republic of Venice, Carnia maintained forms of local self-governance: the Community of Carnia, based in Tolmezzo, managed pastures, forests and collective rights, a model of participatory administration that left a deep mark on the organisation of the territory. Arta took part in this communal structure, and its hamlets — Piano d’Arta, Rivalpo, Cedarchis, Zuglio Basso — each retained their own distinct character.

The modern turning point came with the discovery and promotion of the sulphurous thermal waters. The Fonte Pudia, whose dialectal name refers to the pungent smell of sulphur, had been known for centuries by the local population, but it was the aforementioned 1687 treatise that brought it to the attention of the scientific community. In the 19th century, during Habsburg rule, the first purpose-built thermal establishments were constructed, and Arta gradually transformed into a spa resort frequented by visitors from across the entire eastern Alpine arc. The earthquake of 6 May 1976, which devastated Friuli, also struck Carnia: Arta suffered significant damage, but reconstruction was carried out with careful attention to the recovery of its architectural heritage. The addition of the designation “Terme” to the municipal name, made official during the 20th century, sealed the inseparable bond between the town and its hydrotherapeutic vocation. Today the village bears the visible traces of all these phases: medieval stonework, Renaissance frescoes, 19th-century spa architecture and the work of post-earthquake reconstruction.

What to see in Arta Terme: 5 top attractions

1. The Parish Church of San Pietro

The parish church is located in the hamlet of Zuglio, a few kilometres from the centre of Arta, and is one of the most important religious monuments in Carnia. The current building, with a late-Gothic layout and Renaissance additions, contains a cycle of early 16th-century frescoes of remarkable pictorial quality, with scenes of the Passion and figures of saints attributed to the circle of Il Pordenone. The stone portal and the spired bell tower dominate the small surrounding settlement. Visits are free during opening hours for worship; in the summer months it is often possible to access the small annexed museum of sacred art as well. The parish church deserves a longer stop to study the frescoes in detail.

2. The Fonte Pudia and the Thermal Baths

The sulphurous spring flows a short distance from the centre of Arta Terme and represents the historical and economic focal point of the village. The water, rich in hydrogen sulphide, reaches a temperature of around 10°C and is used for inhalation treatments, mud therapy and balneotherapy at the adjacent spa facility. The Fonte Pudia can be reached with a short walk from town along a signposted pedestrian path. The spring area is freely accessible, while thermal treatments require booking at the facility. The distinctive smell of sulphur can be detected from some distance away: it is the village’s most immediate sensory marker.

3. The Church of Saints Hermagoras and Fortunatus in Piano d’Arta

Dedicated to the patron saints Hermagoras and Fortunatus, celebrated on 12 July, this church stands in the hamlet of Piano d’Arta and is the main place of worship in the municipality. The building houses a carved wooden altarpiece of Carnic craftsmanship and several 17th-century altarpieces. The structure reflects the rebuilding that took place after the 1976 earthquake damage, but retains its original volumetric layout. Its position on a slight rise offers a broad view over the But valley and the surrounding mountains. Access is free during liturgical services. Every 12 July, the patron saint festival draws residents from the various hamlets for religious services and communal activities.

4. The Carnic Museum of Popular Arts “Michele Gortani” in Tolmezzo

Approximately 8 kilometres from Arta, in the main town of Tolmezzo, the museum founded by geologist and senator Michele Gortani in 1920 houses over four thousand objects of Carnic material culture: agricultural tools, textiles, carved furniture, kitchen utensils and traditional costumes. For those visiting Arta Terme, this stop provides the ethnographic context needed to understand daily life in the Friulian mountains between the 17th and 20th centuries. The museum is housed in Palazzo Campeis, an 18th-century building in the historic centre of Tolmezzo. Opening hours vary by season; it is advisable to check the institutional website before visiting.

5. The nature trails towards Monte Arvenis and Val Gleria

Several hiking trails depart from the municipal territory of Arta, climbing the valley slopes up to high-altitude pastures. The route towards Monte Arvenis (1,968 m) passes through beech forests, fir woods and clearings with progressively alpine vegetation. The Val Gleria, a side valley branching off from the Val But, offers a shorter itinerary also suitable for families, with the torrent flowing between erratic boulders and pools of clear water. The trails are marked by the CAI (Italian Alpine Club) and can be hiked from June to October without technical equipment. The elevation gain ranges from 500 to 1,500 metres depending on the chosen destination. These routes are the most direct way to experience the geological and botanical landscape of Carnia.

Traditional cuisine and local products

The cuisine of Arta Terme reflects the food traditions of Carnia, built on mountain ingredients and preservation techniques developed to endure long winters. The most representative dish is cjarsòns, half-moon-shaped ravioli with a filling that varies from hamlet to hamlet — and sometimes from family to family — combining potatoes, mountain herbs (mint, lemon balm, marjoram), raisins, grated chocolate, smoked ricotta and occasionally jam. They are dressed with melted butter and grated smoked ricotta, or with butter and sugar. There is no single recipe: the variability of the filling is itself a defining feature, and every Carnic cook defends her own version. Frico, a crispy disc of melted Montasio cheese with potatoes, is the other cornerstone dish: the crispy version uses only aged cheese, while the soft version adds finely sliced potatoes.

Among designated products, the undisputed protagonist is Montasio DOP, a cooked-paste cheese made from cow’s milk across Friuli Venezia Giulia and parts of Veneto, which in the Carnic mountain dairies takes on distinctive flavours linked to alpine pasture fodder. Smoked ricotta from Carnia, a PAT product (Traditional Agri-Food Product) of Friuli Venezia Giulia, is exposed to beechwood smoke and used both grated over cjarsòns and eaten sliced. Carnic speck, also recognised as a PAT product, differs from its South Tyrolean counterpart through a greater emphasis on smoking over curing. Timau bread, produced in the nearby locality of Timau with rye flour and sourdough, is another reference point of local mountain bread-making.

During the summer, various festivals in the hamlets across the territory offer tastings of these dishes. The patron saint festival on 12 July and the summer events organised by the pro loco associations of the hamlets are the main occasions to sample Carnic cuisine prepared according to local recipes. In Arta and the surrounding area, trattorias and agriturismos offer menus based on cjarsòns, frico, polenta with game and porcini mushrooms gathered in the nearby woods. Mountain honey, produced by local beekeepers from the flora of alpine clearings and pastures, rounds out the flavour map of the territory.

When to visit Arta Terme: the best time of year

The period from June to September offers the most favourable conditions for those who want to combine spa treatments with high-altitude hikes. During these months, daytime temperatures range between 20°C and 28°C on the valley floor, the trails towards Monte Arvenis and Val Gleria are fully accessible, and accommodation facilities operate at full capacity. The patron saint feast of Saints Hermagoras and Fortunatus, on 12 July, marks the central moment of the Arta summer. August brings the highest tourist numbers and the food festivals in the hamlets. September, with the first yellowing of the beech forests, offers settled days and fewer visitors: it is the ideal month for those seeking silence in the mountains.

Winter transforms the valley into a snow-covered landscape from December to March, with minimum temperatures regularly dropping below zero. The thermal baths remain open even in the cold months, and the proximity to nearby ski resorts — Zoncolan, Ravascletto-Sutrio — makes Arta a viable base for alpine skiing and cross-country skiing. Spring, between April and May, is the season of wildflower blooms in the valley-floor meadows and the reopening of mountain refuges: the days grow longer, but the higher elevations may still have residual snow. Autumn, especially October, is excellent for walks in the woods: the foliage of the Carnic beech forests colours the entire valley slope in shades of orange and red.

How to get to Arta Terme

By car, Arta Terme is reached from the A23 Palmanova-Tarvisio motorway by taking the Carnia-Tolmezzo-Amaro exit, then continuing on the SS52bis road towards Tolmezzo and subsequently on the SS52 Carnica towards the Monte Croce Carnico pass. From Tolmezzo to Arta the distance is approximately 8 km, covered in about ten minutes. From Udine the total journey is approximately 75 km (one hour); from Trieste approximately 145 km (one hour and forty minutes); from Venice approximately 190 km (two hours). The nearest airport is Trieste-Friuli Venezia Giulia at Ronchi dei Legionari, approximately 130 km away.

The nearest railway station is Carnia, on the Udine-Tarvisio line, located approximately 10 km from Arta Terme. From this station, local bus services operated by TPL FVG connect the valley floor with the localities of the Val But. The service is more frequent during the school term and reduced during summer and holiday periods: it is advisable to check updated timetables on the website of the Municipality of Arta Terme. A car remains the most practical means of transport for moving between the hamlets and reaching the starting points of the hiking trails.

Other villages to discover in Friuli Venezia Giulia

Those who decide to explore Carnia and the mountainous Friuli starting from Arta Terme can put together a multi-day itinerary taking in other localities that deserve attention. Heading up the Tagliamento valley, you reach Ampezzo, a Carnic centre that shares with Arta its position along one of the main valley routes of the region. Ampezzo, situated at the confluence of the Tagliamento with the Lumiei torrent, retains a compact historic core and serves as an access point to the Regional Forest of Cansiglio di Carnia and the hiking routes of the Canal Grande di Socchieve. The distance from Arta is modest — roughly thirty minutes by car — and the road connection crosses the upper valley landscape with notable views of the Tagliamento’s river morphology.

Moving southward, towards the plain, and turning eastward, you reach Bordano, known for the mural art project that transformed the facades of its houses into an open-air exhibition dedicated to butterflies. The village sits at the foot of Monte San Simeone, in a position marking the transition between the mountains and the hilly zone. Bordano and Arta Terme represent two different ways of inhabiting the Friulian territory: the former linked to a contemporary artistic intervention born out of post-earthquake reconstruction, the latter rooted in a centuries-old thermal and alpine vocation. Combining them in a single trip means crossing the geographical and cultural variety of Friuli in little more than an hour’s drive, moving from the deep Carnia to the foothill belt. For a deeper understanding of the regional context, it is useful to consult the dedicated page on Arta Terme on Wikipedia and the information available on the Touring Club Italiano portal.
