This epic mountain bike adventure connects the panoramic slopes of Karavanke mountains, central Slovenia, the remote world of Karst, and the Adriatic coast. Great single trails and highly diverse terrain provide for lots of MTB excitement. 

The Trans Slovenia 04 expedition focuses on offering an unforgettable experience by including as many excellent single trails as possible. This Slovenia bike trip begins in the village of Bleiburg, which is located next to the Austria-Slovenia border and the Petzen Flow Trail, the longest of its kind in Europe. The tour sets off with forest single trails, which were part of the Enduro World Series competition in 2018. Before reaching the Solčava panoramic road above the picture-perfect Logarska Valley, you get the opportunity to bike through abandoned mine tunnels.

Riding across the Velika Planina, arguably the oldest shepherds’ settlement in Europe that remains active up to date, leads to the medieval town of Kamnik. From here on, fun trails run directly to the center of Ljubljana city, where you can enjoy the atmosphere of one of the greenest capitals in Europe and bike around the UNESCO-listed Ljubljana Marshes

Turning back to the hills, you eventually arrive at a very unique natural phenomenon, the intermittent Lake Cerknica. In the next part of this Slovenia bicycle tour, you pass by the world’s famous Postojna Cave and the UNESCO-protected Škocjan Caves. The final downhill ride from the Karst plateau leads to Piran, a romantic city on the Adriatic coast, which reminds of Venice.

This Trans Slovenia bike tour presents an alternative trail for starting the 2000 km long Trans Dinarica tour.

DAY 01


DistanceDistance: 13,5 km
DistanceElevation: 430 m

The Trans Slovenia 04 tour sets off in the Austrian village of Bleiburg. The first day is devoted to single trails. Single Trail Park Jamnica invites with high-quality MTB trails running through forests and over meadows of the north-eastern part of the Karavanke. The most enthusiastic bikers can also try out the 10-kilometre fun-packed Petzen Flow Trail, the longest of its kind in Europe. In 2018, the Petzen and Jamnica hosted the Enduro World Series event, where bikers experienced some of the longest stages in EWS history.

The technical description of the stage only covers the route from Bleiburg to Jamnica without the Single Trail Park and Flow Trail.

DAY 02


DistanceDistance: 45-47 km
DistanceElevation: 1405 m

The second day of this Trans Slovenia bike trip continues with some fun single trails in the Jamnica Single Trail Park. When you return to the valley, it is time to go underground. Biking from one valley to another through the abandoned tunnels of the Mežica mine is a very special experience. 

The underground ride is nicely contrasted by the second half of the day. The route leads from Črna na Koroškem to Mt. Raduha and eventually reaches a beautiful panoramic road high above the Logarska Valley. You might want to take a short break here and enjoy the views over the mighty peaks of the Kamnik–Savinja Alps. The stage ends in the tranquil village of Podolševa

DAY 03


DistanceDistance: 55 - 61 km
DistanceElevation: 1225 m

On the next day you are greeted by the mighty walls of the Kamnik–Savinja Alps. When completing the panoramic road, you descent towards the Savinja Valley, where the next challenge is waiting. The uphill ride to the large pasture plateau of Velika planina is however, truly rewarding. Velika planina is home to one of Europe’s few surviving high mountain herdsmen villages where traditional Alpine herdsmen’s culture is still cultivated. This scenic high-mountain plateau is a hiking paradise for families, photographers, and those who seek a relaxing day out in unspoilt nature.

From the green pastures, a long descent leads to Kamnik, which boasts the prettiest medieval old town in the country.

DAY 04

Kamnik - Ljubljana: THE GREEN CAPITAL

DistanceDistance: 46,5 km
DistanceElevation: 1000 m

The epic Trans Slovenia cycle route continues. If you expect the MTB character of the tour to be put on pause when you approach the capital city of Ljubljana, you are mistaken. In fact, endless interweaving trails lead across the hills surrounding Ljubljana directly into the city center. Welcome to the only European capital with direct access to some of the best MTB trails in the country. 

Ljubljana is one of the smallest capitals of Europe, but it’s huge in terms of the variety of what you can do, see and taste. 50.000 university students give it its youthful appeal, and as an economic and cultural hub of Slovenia, it has a lot to offer to locals and visitors alike. The city center has long ago banished cars to make room for more outdoor cafes and restaurants, cultural events, open-air markets and of course, bike lanes.

DAY 05

Ljubljana - Postojna: THE WONDERS OF KARST

DistanceDistance: 68 - 72 km
DistanceElevation: 1300 - 1550 m

Day 5 of biking in Slovenia starts with a ride across the UNESCO-listed Ljubljana Marshes, a protected area of natural wetlands and peat bogs, which is important due to its rare animal and plant species and the remains of prehistoric pile dwellings. 

The stage continues with an ascent to Mt. Krim, one of the most recognizable landmarks of the Ljubljana basin. A gentle descent then leads to the village of Rakitna, which is embraced by lush spruce forests and known for its healthful climate.

The second part of the day is characterized by a scenic ride along the intermittent Lake Cerknica. The lake appears every year for several months before completely disappearing during the dry season. When the lake bed is full, it becomes the largest lake in Slovenia. The final stop of the day is located just above the entrance to the world-famous Postojna Cave, a visit of which is highly recommended.

DAY 06

Postojna - Divača: CAVE HOPPING

DistanceDistance: 43 - 51 km
DistanceElevation: 610 - 1070 m

On the following day of Slovenia cycling holidays, the route turns towards the seaside. A moderate climb to Vremščica is rewarded by ample views of the Julian Alps, Dolomites and Mt. Nanos. 

A thrilling downhill trail runs across the southern slopes of Vremščica right into the heart of the Slovenian Karst, a region known for numerous caves, vineyards, small secluded villages and friendly locals. MTB Slovenia carries on along the stony landscape, eventually reaching the stunning underground world of the Škocjan Caves. Due to their exceptional significance, these caves were put on UNESCO list of world heritage sites as early as 1986. 

The mountain bike adventure of the day ends in Divača, where you can relax and enjoy the serene landscape, abundant flora, various karstic wonders, and mouth-watering culinary delights.

DAY 07


DistanceDistance: 62 - 68 km
DistanceElevation: 985 - 1230 m

The last stage of the Trans Slovenia mountain bike trip says farewell to the dry lands of Karst and takes you all the way to the Adriatic Sea. The first stop of the day is the medieval Socerb castle, which proudly overlooks the Gulf of Trieste. Next, you ride down to Osp, one of the oldest villages in Slovenia, which was first mentioned back in 1067. 

The trail soon descends to the sea level and you arrive to the city of Koper, situated at the Slovenia’s 47-kilometer coastline. From here on, you follow the Parenzana railway track, a now defunct narrow gauge railway that connected Triste and Poreč in the beginning of the 20th century. After passing through a few tunnels, the route eventually reaches the city of Piran, which is, according to Lonely Planet, a small slice of Venice in Slovenia. Its old town, full of Venetian Gothic architecture, is known as one of the best-preserved historical towns on the Adriatic. For the best sunset views, climb the city walls.
