Bobotov Kuk from Black Lake and back.

The hike to Bobotov Kuk from Crno Jezero (Black Lake) is the longest and most demanding route, offering a tough but rewarding challenge. While it’s a great option for experienced hikers, I would personally consider it the least favorable due to its steep ascent and difficult terrain.

The journey begins at the main trailhead by Black Lake, where you’ll need to pay a park entry fee of €5 per person. From there, head right along the lake’s edge, crossing a small stream and gradually entering the forest.

At first, the trail meanders through the woods, offering a relatively easy walk. But as you climb higher, the terrain becomes significantly more rugged. You'll soon find yourself navigating loose, rocky scree that can feel tricky underfoot—think less “confident hiker” and more “slippery mess.” Even in summer, you might encounter patches of snow blocking the path, though these are generally easy to pass due to the well-trodden paths of earlier hikers.

Though the incline is moderate at first, it gets noticeably steeper as you approach the final section. The last stretch towards the saddle is long, rocky, and grueling, serving as a true test of your stamina. It can feel endless at times, so brace yourself for a challenging finish.

At the top, there’s a cable to help you climb to the summit. Given the exposed nature of the final ascent, it’s wise to wear a helmet for protection from rocks that could potentially fall from above—something that’s especially important since hikers above might inadvertently dislodge them.

The round trip typically takes about 10-12 hours and involves a climb of over 1300 meters in total. For a more enjoyable experience, it’s crucial to start early and be in good physical shape.

Along the way, you’ll pass two water springs. However, don’t rely on them for hydration—there's always the risk that they’ll dry up during the summer, leaving you without a water source.

You’ll also encounter a katun (mountain hut) that offers drinks for €4, but it’s not guaranteed to be open, so it’s best to plan ahead and bring your own supplies.
