Rieserferner-Ahrn Nature Park partially takes its name from the Rieserferner Group (Gruppo delle Vedrette di Ries/Rieserfernergruppe). This small mountain range forms part of the Central Alps's High Tauern (Alti Tauri/Hohe Tauern). There are 38 peaks over 3,000 m (9,842 ft) in elevation in Rieserferner-Ahrn Nature Park.

At the northern end of Rieserferner-Ahrn Nature Park is the Ahrn Valley (Valle Aurina/Ahrntal), Italy's snowiest and northernmost valley. Rieserferner-Ahrn Nature Park is renowned for its snowfall and contains the highest percentage of glaciers of any South Tyrolean nature park.

At the northern end of the park between Ahrn Valley and Rein Valley (Reintal) is the Durreck Group (Durreckgruppe), a mountain massif that includes several well-known mountains like Dreieckspitze (Triangolo di Riva) (3,031 m/9,944 ft).

Further to the northeast is the Venediger Group (Venedigergruppe). The Venediger Group is home to Dreiherrenspitze, the park's highest summit. To the north of the Venediger Group is Italy's northernmost point, the Vetta d'Italia (Klockerkarkopf) (2,912 m/9,554 ft).

Important landmarks in Rieserferner-Ahrn Nature Park include the Riva Waterfalls (Cascate di Riva/Reinbachfälle), a series of three waterfalls, the largest of which is over 50 m (160 ft) high. Another landmark is the Earth Pyramids of Platten (Piramidi di Plata/Erdpyramiden von Platten), a series of spire-like natural sand towers capped with stones.

Antholzer See (Lago d'Anterselva) is the largest lake in Rieserferner-Ahrn Nature Park and the third-largest natural lake in South Tyrol, with a surface area of 43 ha (104 acres).

Notable settlements in and around Rieserferner-Ahrn Nature Park include Burneck, Rasen-Antholz, and Riva di Tures.

Geology

A part of the Central Alps, Rieserferner-Ahrn Nature Park formed during the Alpine orogeny. The Alpine orogeny is a mountain-building event that began during the Late Mesozoic approximately 60 million years ago and is ongoing in some Alpine regions.

The area which is now Rieserferner-Ahrn Nature Park began forming around 60 million years ago when the small Adriatic Plate separated from the African continent. The Adriatic Plate moved north, colliding with the Eurasian Plate and overriding it by approximately 150 km (93 mi).

High Tauern at Rieserferner-Ahrn Nature Park, Italy

The convergent movement between the Adriatic Plate and Eurasian Plate caused subduction at the edge of Europe, pushing land into the hot magma of the Earth's mantle.

Roughly 30 million years later, the Eurasian Plate penetrated the African Plate through existing fissures from past tectonic activity. This movement created an African and Eurasian geological fusion with igneous tonalite masses partially covering the existing African gneiss zone.

Over the next 20 million years, the tonalite overlay of the African slab eroded, exposing the gneiss and shale below. Remnants of the Adriatic Plate formed into a series of three Austroalpine nappe stacks extending from Brenner (Brennero) to Katschberg, known geologically as the Hohe Tauern Window.

Today, Rieserferner-Ahrn Nature Park is one of Italy's snowiest and most glaciated parks. It's home to over three dozen summits over 3,000 m (9,842 ft), including Rötspitze (Pizzo Rosso) (3,495 m/11,467 ft), Schneebiger Nock (Monte Nevoso) (3,357 m/11,017 ft), and Durreck (Cima Dura) (3,135 m/10,295 ft).

Ecology

From the snowy floor of the Ahrntal to high mixed coniferous forests, Rieserferner-Ahrn Nature Park is home to an array of habitats where flora and fauna thrive. Read on to learn about Rieserferner-Ahrn Nature Park's wildlife.

Fauna

Some of the largest mammal species hikers are likely to encounter in Rieserferner-Ahrn Nature Park include chamois, red deer, and roe deer. Other smaller mammals present include mountain hares, alpine marmots, foxes, badgers, and pine martens.

High Tauern at Rieserferner-Ahrn Nature Park, Italy

The forests of Rieserferner-Ahrn Nature Park are home to many bird species, such as siskins, crossbills, woodpeckers, and nutcrackers. Elusive Eurasian pygmy owls and western capercaillies also succeed in the park's mixed forests.

On the park's pastures nests one of northern Italy's most highly protected bird species, the golden eagle. Water pipits are one of the common birds found on Alpine pastures.

The mountain flowers that grow across the Alpine pastures attract various insects, including bumblebees, beetles, grasshoppers, dragonflies, and butterflies.

Flora

Most of Rieserferner-Ahrn Nature Park's landscape consists of meadows, mixed coniferous forests, rocky slopes, and glaciers.

Spruces dominate the park's montane forests between 800 m (2,624 ft) and 1,400 m (4,593 ft). Larches are present in sunnier areas where there are fewer spruces. Some deciduous trees can be found here as well, including mountain ashes.

Spruces, Swiss pines, and larches constitute most of the forests between 1,900 m (6,233 ft) and 2,200 m (7,217 ft). In humid areas, mountain pines and green alders are present.

Across the meadows and pastures of Rieserferner-Ahrn Nature Park grow many flowering plants, such as cat's feet, arnicas, golden cinquefoils, and bearded harebells.

Alpine rock jasmine is a common plant above 3,000 m (9,842 ft). Other plant species hike could encounter high on the Rieserferner Group's rocky high mountain outcrops include Alpine toadflax, red saxifrage, and musky saxifrage.

Human History

During the Middle Ages, humans traveling between Pinzgau and Zillertal first settled in Rieserferner-Ahrn Nature Park. Remnants of Austrian Pinzgau culture and traditions can be identified in the region. For example, many farmhouses are built with a small bell tower, typical of the Pinzgau region.

Over time farmhouses grew into hamlets, usually centered around a small church and a few artisans. Despite its elevation and unforgiving conditions, Ahrntal has been an area of heavy traffic for over 1,000 years.

On the Krimmler Tauern high mountain pass, the remnants of the old international trade route are still visible. This international trade route linked regions on either side of the Alps. One of the most important links was between Salzburg and northern Italy. Wine and salt were among the most commonly traded commodities.

Transhumance farming was another reason why the Ahrntal was a busy area. To this day, farmers still move their livestock from Alpine pastures towards Salzburg, sometimes through deep snow. Large Alpine pastures exist on the slopes above the treeline, where cattle graze in the summer.

Rieserferner-Ahrn Nature Park first came to the public's attention as a tourist and hiking destination in the late nineteenth century. In the late 1800s, the magazine for the German-Austrian Alpine Association wrote a piece on Rieserferner-Ahrn Nature Park, which raised awareness about the area's beauty.

Rieserferner-Ahrn Nature Park was established in 1998 to protect the culture and nature of the Ahrntal and the surrounding mountains and valleys.

Due to its isolated location and snowy conditions, hikers should come well-prepared when visiting Rieserferner-Ahrn Nature Park. Bring appropriate hiking gear, warm clothing, and plenty of food and water. Note mountain huts along your intended route, and inform others of your itinerary. Check local weather forecasts before hiking in Rieserferner-Ahrn Nature Park.

Read on to learn about some of the best hikes in Rieserferner-Ahrn Nature Park.

Dreiherrnspitze / Picco dei Tre Signori

Dreiherrnspitze (3,499 m/11,480 ft), or Picco dei Tre Signori, one of the most famous and climbed mountains in the Venediger Group. The mountain takes its name from being the historic tripoint between the earldoms of Tyrol, Görz, and the Bishop of Salzburg.

The highest summit in the park, Dreiherrnspitze's normal route can be accessed on its western flank from within Rieserferner-Ahrn Nature Park. Dreiherrnspitze is a demanding mountain only suitable for experienced mountaineers, with crampons, ice axes, and ropes necessary.

You can pick up the trail to Dreiherrnspitze from Rifugio Giogo Lungo (Lenkjöchlhütte) (2,603 m/8,540 ft). The best way to reach Rifugio Giogo Lungo is on the No. 11 trail from Casere (Kasern). The hike from Casere to Rifugio Giogo Lungo takes approximately 3 hours.

The route up Dreiherrnspitze's western flank from Rifugio Giogo Lungo is considered the easiest and is rated PD (not very hard) on the Swiss Alpine Club's (SAC) mountaineering scale. Part of this walk leads over the Umbalkees glacier, but the route is well-marked.

Most of the mountain's difficulty is further on the ascent, when you'll need to watch for crevasses and snow cornices. The steep slope onto the summit ridge is hazardous, with conditions worsening depending on the amount of snow. The hike from Rifugio Giogo Lungo to Dreiherrnspitze takes approximately 6 hours to complete.

Vetta d'Italia / Klockerkarkopf

The Vetta d'Italia (Klockerkarkopf) (2,912 m/9,554 ft) marks the northernmost point in Italy, making it a must for many hikers visiting Rieserferner-Ahrn Nature Park. It's located at the eastern end of the Zillertal Alps, near the Birnlücke pass, which connects to High Tauern.

Due to its position between the Zillertal Alps and the Venediger Group, Vetta d'Italia affords breathtaking views, especially from Großvenediger (3,657 m/11,998 ft) to Rötspitze (Pizzo Rosso) (3,495 m/11,467 ft).

The Vetta d'Italia is almost exclusively climbed from its southern side due to the relatively short, marked trail that leads to the summit. The route from the north is a long, arduous walk from Krimml.
