Vodene kolesarske avanture

4th Corona Challenge

Bike Slovenia in collaboration with Visit Postojna, has invited you for the fourth time to a very special challenge - the 4th Corona Challenge.

The circular Corona Tour takes place along the borders of the municipality of Postojna, with 80% of the route consisting of forest dirt paths, as more than half of the municipality of Postojna is covered by forest. We ride away from the hustle and bustle of civilization, through the Javornik forests, at the foot of Nanos, and finally past the ruins of the once-mighty Baroque Hošperg Castle. You can find a more detailed description of the Corona Tour below.

The tour, with almost 100 kilometers and 2.000 vm is a real treat for endurance cyclists who enjoy nature. It's a perfect ten! We recommend it to cyclists with tires with good traction and at least front suspension, but it's also interesting for gravel cyclists.

In short:

BIKE SLOVENIA AND VISIT POSTOJNA.

The starting/ending point of the route is optional, we suggest cycling clockwise. If we start from Postojna, we first ride towards Unc and just before the intersection for Kalič, we turn right onto a gravel road and climb up into the Javornik forests. We reach the highest point of the Corona tour, followed by a descent, and then we join the Javorniška road, climb a little, and then descend past Poček/Bil (warning: this area may be closed during the week due to military activities, check the Slovenian Armed Forces website) to the village of Žeje. We cross the Pivka river bed past Tišlerjev mill (warning: do not cross the bridge as it is too dangerous; if there is water in the river bed, drive around) to the village of Prestranek (store), and then to the village of Slavina, where we start climbing on a gravel road towards Laž. We pass by a quarry , descend to the Hudičevec farm, and continue on an asphalt road to Razdrto. We turn across the highway (water) to Veliki Ubeljski and onto the path to the village of Strane, past the oldest yew tree (water). We continue the ascent into the Nanos forests to the intersection for Suhi vrh, followed by a descent towards Bukovje, but soon we turn left and climb through several intersections to the Podkraj-Kalce road, from where we turn back onto the gravel road and continue, with ups and downs, all the way to the village of Liplje (regional road PO-Logatec). We ride on the asphalt road to the cemetery in Planina (water) and then to the ruins of the once mighty Hošperg castle (Haasberg). From here, we climb again on a gravel road past the Unška koliševka (125 m deep sinkhole), descend to the PO-Unec road, and take a short ride back to Postojna where we return as winners of the Korona tour or cycling on the outer borders of the municipality of Postojna.
