Subra (circular route), grade I+

From the parking area, follow the yellow signpost "Subra" uphill and walk on a gravel track gently uphill. After a while, a marking points left and you shorten a hairpin via an old stone path to rejoin the track, which initially continues flat, then climbs steeply in switchbacks to the saddle "Vratlo" and then gently downhill to the shelter "Za Vrtatlom", which is managed in summer.

Just below the shelter at a fork, take the marked route left towards "Subra". The footpath leads along a shallow karst basin and reaches another fork where you follow the markings left. At a subsequent fork, also keep left. You walk through light woodland gently uphill and reach another signposted fork where you continue straight towards "Subra". The route goes flat again through open terrain along a karst depression, then up a wide ridge past a stone house. Beyond, in the forest, the route gradually climbs more steeply and soon reaches the edge of the karstic Subra plateau in blocky terrain, where despite the dense markings you should watch carefully for fissures and cross cracks. You pass several vertical shafts that are labeled (e.g., Nikolina Jama, 188 m deep) and ascend in stages through the karst labyrinth. Beyond the plateau the route reaches forest again and leads steeply uphill there. You reach a junction left which leads to the viewpoint "Vilino Guvno" (very worthwhile!). After returning to this junction, you continue climbing straight ahead and pass the "Zaklon Shelter". Soon you follow a horizontal rock ledge to the right back to the main ridge and then steeply up in rough block terrain, past a junction to a spring and finally surprisingly easily over some karst steps to the gentle summit dome of Subra.

For the descent, follow a mountain ridge from the summit northeast along markings downhill. Soon it goes steeply down over karst steps and curves to the right, then through scattered pines and down to a gorge where you have to climb down (grade I+). Beyond that follows a traverse with unpleasant narrow sections leading to a descent into an extremely steep gully down to the right. Another traverse crosses a deep rock crevice, then continues downhill through very rough karst terrain. The next crossing to the left goes almost flat through very rugged rock for quite a while. Finally, you go down another gully and then diagonally left below it over a slope to a rock plateau where a junction to a spring is marked right. Straight ahead the markings continue flatter through the karst and soon turn right. You reach the labeled junction to Somova Cave and follow the markings left further towards "Za Vratlom". Here the terrain becomes flatter and the path gradually gentle. You cross a forest and reach a fork where you have to turn sharply right towards Vratlo Shelter. Behind a crest in the forest at another fork keep left (Vratlo). Soon you pass Vodena Cave where water drips and at the next crossing reach the ascent route, which you follow left passing the shelter back to the starting point.
