Kohászok route (Kohász blue trail), section 3: Járdánháza – Ózd – Sáta
Winding in the shadow of mountains is the country’s most scenic long-distance hiking trail outside the Blue Trail, the Kohászok route. On its third section, from a remote, treeless hilly area, we look at the Bükk and discover the surroundings of Arló Lake that recall Transylvanian regions.
This remote section of the Kohászok route has two faces: mostly a forest walk with some beautiful panoramas, but near Ózd it offers unexpected landscapes. The hills near the town, evoking Transylvania with their grassy surfaces, steep slopes, and landslide-shaped forms, provide the most surprising sight on the whole hike, and the Arló Lake is memorable due to its pine-covered, mountainous surroundings. Some sections have gained notoriety for difficult passage, and closed clothing is recommended during the summer season due to the "jungle fight".
A nomadic hiking experience in the back yard of the mountains
The "Kohász blue" from Salgótarján to Diósgyőr meanders under the cover of the higher parts of the Northern Central Mountains, therefore mostly little-traveled, but surprisingly rich in natural sights. The 119 km route is enjoying a renaissance and is the country’s most exciting trekking route that can be completed in a relatively short time. It crosses the Medves region, the Vajdavár region, the hills of Ózd, the Uppony Mountains, and the Bükk, leading through wild, sometimes almost impassable terrains while continuously opening breathtaking views of Hungary’s most dynamic relief, framed from the south by the long ridge of the Mátra and the plateau of Bükk.
There is no boring day or two alike on the Kohász blue: the landscape is surprisingly varied, with spectacular views and atmospheric forest sections following each other. Sometimes short detours are necessary to reach the best viewpoints (e.g., to Pécs-kő, Nagy-kő of Bárna, or Kalica Hill). The hike is relatively nomadic: it passes few settlements, some days the distance is under 25 kilometers, but the terrain is excellent for camping and bivouac. Near Bárna, Hungary’s first bivouac hut awaits hikers, and the Bükk section is full of comfortable overnight spots.
The Kohászok route then and now
As evident from the badge motif obtainable upon completion, the route connects former iron industry centers: Salgótarján, Ózd, and Diósgyőr. The route was marked by Ózd hikers between 1968 and 1970. With the decline of the iron industry strongholds, the route’s popularity diminished, and much of the rarely used paths were reclaimed by nature. The Kohászok route was revived in the early 2020s: an enthusiastic group took over its care, new stamps were made, and path maintenance is ongoing. The hiking booklet can be downloaded before departure (see links), and finishers receive a metal badge and certificate after payment.

Author’s recommendation
- It is worth breaking the hike in Ózd, allowing time to visit the steel mill transformed into an experience park or to eat in a restaurant.
- The Arló Lake is truly spectacular only from the mountain towering beside it (on the north side). We can climb up there on an unmarked path.
Derived from the technical difficulty and the stamina requirements.

Járdánháza – Ózd: Transylvanian atmospheres and mining sights
Járdánháza is not exactly a hospitable place, and the Kohászok route quickly cuts through it: straight across the meadows, approaching the next landscape unit, the hills around Arló with their striking appearance even from afar. Between steep, grass-covered sides and occasionally slipped small hills, we find a road by car to the Arló Lake. The lake, surrounded by vacation homes and hardly accessible from them, is partly artificial and partly natural in origin: the slope of Csahó hill slipped three times due to blasting in mining, and the last landslide in 1929 permanently blocked the stream’s path, creating the stagnant water.
The mark first leads to the forest edge, and be alert when it turns back to the lake shore: at the meeting of two paths stands a signboard, on the back of which we find the stamp. The route does not lead down to the shore but twists among hills with peculiar visual worlds from the far end of the water surface. Beside the Csahó Valley, low but steep hills covered with semi-dry grass, shrubs, and pines ripple, and their slipped, dented shapes recall certain points of Transylvania.
Reaching the first ridge, a large trace of slip “illuminates” on one hilltop edge on the left, but the whole crooked, open landscape is hardly forgiving. Turning right from the valley, we climb out from a green, amphitheater-like basin along a narrowing, sandy deep path, on the other side already along a gas pipeline corridor, then descend into Somsály in the forest. The typical mining settlement, formed during the early 19th century boom of coal mining in Ózd, sank into “coma” at the end of the 20th century along with the region’s industry. Along the tourist route, we can see the ruined, massive but crumbling miners’ church reminiscent of a blast furnace.
We climb up the street to the edge of the village, and before the pine forest, from a ladder we can still look back to the Vajdavár region: there rises the Ökör Hill and its group, in the background the Mátra also appears. Sometimes hard to follow, overgrown in places, elsewhere a pine grove path leads to Ózd, attention to the markings is necessary. From Bükk Hill’s clearing, the town is already visible, behind it the mountains of the Carpathians, up to the Low Tatras. We walk into the town among houses with gardens, and at the entrance of the Digital Power Plant we can stamp. The former ironworks is the mid-19th century creation of the Gömör iron industry with a long history, originally planned to be built near Mátra but finally settled on a remote small village, Ózd. The one and a half century production collapsed along with the local industry after the regime change. Today, the Digital Power Plant and the National Film History Experience Park operate on part of the factory monster.
Ózd – Sáta: easy hillside walk
The next section is a sort of resting walk between mountains. Heading out from Ózd, we first bypass the Hétstelep segregated area, and from the houses on the hill, we can still look back at the town. At the end of the street, the markings invite us to the right, and beside a fence, we start climbing the most troublesome section of the Kohászok route: the vegetation often completely entangles this stretch, which the route maintainers try to keep clean with laborious work. A long forest hike follows over low hills, in mixed forests, with only one viewpoint to the surrounding rolling landscape. If we look out to the edges of pastures near the tourist path, we can note that the size of the undulating plateau overlooking Bükk is growing, as we are already heading south.
We cross the closed Putnok railway line and walk under open hill ridges to Sáta on asphalt road. In the center, in front of the church, the K mark changes to K+ – because the Kohász blue joins the National Blue Trail in the next village, it was necessary to somehow distinguish it. On the opposite side of the village, we find the Sáta stamp in the pub next to the street.
