The wildest and the greenest trail run in Slovenia

Discover the wilderness of the Kočevje forests through trail running

If we had to find some of the wildest and most remote corners of Slovenia, we would definitely look in the Kočevje region. Vast forests, home to many wild animals, cover a significant part of Kočevsko. They also hide many undiscovered gems—primeval forests, breathtaking trails, and stunning nature—which is at its most beautiful when dressed in lush green. We have selected some of the most exciting spots you will get to discover during our event.

The 5 most fascinating sights along the routes

The wilderness of Kočevski Rog, where you can still find untouched primeval forests, is also home to many wild animals, including lynxes, wolves, wild cats, deer… and, of course, the most famous inhabitants of the Kočevje forests—bears. The Kočevje primeval forests have gained international recognition and are included in the prestigious UNESCO World Natural Heritage list.

1. Primeval forest Rajhenavski Rog

The Rajhenavski Rog primeval forest is one of the best-preserved primeval forests in Slovenia, located in Kočevski Rog. It covers approximately 51 hectares and is part of a larger protected forest area. This extraordinary ecosystem consists of ancient beech and fir trees, some of which are over 500 years old. The forest is uninhabited and untouched by human activity, allowing natural tree growth and decay.

All runners taking on the 30 km or 60 km distance will pass along the edges of this magnificent part of Kočevski Rog.

2. Peaks and scenic viewpoints

The courses also feature some ascents. The most famous peaks include Veliki Rog, Lovski vrh, and Fridrihštajn Castle, which is part of Friday’s vertical run.

  • Veliki Rog is the highest peak of Kočevski Rog, reaching 1,099 meters. Located in the heart of the forest, it is a popular spot for hikers and nature lovers. At the summit, there is also a lookout tower, so if you’re not in too much of a hurry to reach the finish line, take a moment to enjoy the spectacular view.

     

  • Lovski vrh is a scenic hill near Kočevje, reaching just over 900 meters. It is part of the Kočevski Rog forest and offers stunning views of Kočevska Valley and the surrounding forests. The area is rich in wildlife, including bears, deer, and other wild animals.

     

  • Fridrihštajn Castle is now a picturesque ruin above Kočevje, sitting at 970 meters above sea level. It was built in the 15th century by Friderik II of Celje for his beloved Veronika Deseniška. The castle was soon destroyed, leaving only the remains of its walls. Nevertheless, it is a popular hiking destination, offering breathtaking views of Kočevsko and its forests.

3. The Queen of Rog

The Queen of Rog is a majestic ancient fir tree near Rajhenavski Rog primeval forest, one of Slovenia’s most magnificent trees. It stands 55 meters tall, with a trunk circumference of around 500 cm. It is several centuries old and symbolizes the untouched nature of Kočevski Rog.

The race courses pass right by the Queen of Rog, so keep an eye out for this natural wonder!

4. Abandoned villages of the Kočevje Germans

On the longest course, you will also pass several abandoned villages, once home to the Kočevje Germans.

The Kočevje Germans (Gottscheers) were a German-speaking community that settled in the Kočevsko region in the 14th century. They came from Tyrol and Carinthia, maintaining their language, culture, and traditions for centuries. During World War II, most of them left Kočevsko, and their villages were abandoned or demolished after the war. Today, their heritage lives on in historical records, place names, and cultural preservation efforts.

5. Kočevsko Lake

The main event venue is located near Kočevsko Lake, making it a perfect place to cool off after your run or relax before or after the event.

Kočevsko Lake is one of the cleanest lakes in Slovenia and a popular spot for swimming, fishing, rowing, and walking. It is surrounded by forests, which provide a habitat for many wildlife species.

Green meadows and the mysteries of the forest will captivate you as you run

The forests and meadows along the trails offer an incredible setting for trail running. Trail running is about experiencing nature, and there are few places that offer a more primal connection to the wilderness than Kočevsko. As the destination itself claims: “Wild. Yet welcoming.”

For runners, it’s especially exciting to know that more than 90% of the race takes place on trails. You’ll only see about 100 meters of asphalt at the start and another 100 meters at the finish. The rest of the course will take you through stunning forest and meadow trails, hidden deep within the Kočevje forests.

Let’s keep nature untouched

The Kočevsko Outdoor Festival takes place in an extraordinary but fragile natural environment—the Kočevje forests. Everyone involved—organizers, event partners, participants, and visitors—has an essential role in protecting this unique ecosystem.

That’s why we have prepared some guidelines on how to be an environmentally responsible visitor.

The mystical forest, which is also a precious habitat for many wild animals, will surely be grateful for our efforts.

Run solo, in pairs, or as a family

At the Kočevsko Outdoor Festival, you can choose from five distances: 5 km, 10 km, 15 km, 30 km, and 60 km. On Friday, you can also take part in a vertical run (2.6 km with 475 m elevation gain).

A special feature of this event is the option to register as a pair (10 – 60 km) or as a family for the 5 km race. It’s a perfect opportunity for those who want to explore the Kočevje forests together and a great choice for those who might feel a little nervous about running in the wild. After all, everything is easier in good company! 😉
