Cerknica to the Karawanks and east to a hole in a slope
Table of Contents
Brief #
This is not a travel plan. Nobody is booking anything.
These are real places. Do not invent over them or relocate them. Where detail is thin, say so and dig; where it is approximate, treat it as approximate.
Fixed: the order of places, both border crossings on foot and off the road, the railway stations as the ends of the walking legs, the cave as destination.
Fluid: season, weather on the day, who these people are, why Idrija, what goes wrong, how long they take.
The group is moving because others will eventually find out what was done in the Cerknica region, and they want to be elsewhere first. They carry no papers. That single fact governs the whole route: no flights, no hotel registers, no international services where police board at borders, and a standing preference for crossings where nobody is standing at all.
It also sets the risk arithmetic. A check is not an inconvenience here, it is a stop — so the ranking measure throughout is the probability of being asked, not legality. That is why the Seeberg is crossed on a cart track rather than the road, why the Burgenland version was argued and lost, why Marchegg is approached on the terminating train instead of the through service, and why the route takes the long way round Bratislava. Where a choice looks eccentric, it is usually that arithmetic showing.
Low profile is the other half. They avoid towns where they’d be remembered, use cash, sleep in fields and huts rather than anywhere that wants a name, and would rather be unremarkable on a marked path than the only people on an unmarked one.
Detail level. Descriptive, not a walking guide. No timetables. But this may be run as a scenario, so granularity is expected to expand at points of play — who is at a junction, what a driver asks, what a farmyard sounds like at six. The prompts under each section are where to start.
Part one — Cerknica to Austria #
The journey runs from an intermittent lake in Notranjska, west and north over the Idrijca hills to a manor above a mining valley, then north-east into a valley that ends at a wall of mountains, then up a cart track over the border, then down the far side to the Drava.
Two things carry it. The detour to Idrija is deliberate and costs a day. And the border is crossed on a track, away from the road, in country with no fence worth the name.
The lake #
Lake Cerknica is not always a lake. It fills and drains on its own cycle; in a dry phase the bed is pasture with roads across it. In a wet phase the water comes back and the roads go under. The town sits above it on dry ground and has always known which phase it is in.
The karst here is sinkholes and swallow-holes, dry stone, scrub, water that behaves impossibly — springs that appear and stop, a stream that runs a few hundred metres and vanishes into a hole in a field.†
Easy country: flat, open, full of places to be unseen.† A poor place to be followed.†
Prompts: the fill-and-drain cycle; which roads go under and when.
The detour west #
The road climbs out of the basin and over the Črni Vrh hills, beech and spruce, small holdings, then drops into the Idrijca gorge.
Spodnja Idrija lies under a pilgrimage church on a rock, Mary on the Rock, recorded since the twelfth century. Upstream is Idrija and the mercury mine that made the valley — the second-oldest in Europe, worked for five centuries, closed within living memory.† The valley wears the mine the way a body wears an old injury.†
Kendov Dvorec stands on a rise above the river: an estate recorded from 1377, seat of the Kenda family, four centuries of provincial money and respectability. Thoroughly restored, comfortable rather than raw.† Good for a bed, a bath, a dining room with white cloth.†
Prompts: the gorge road in June; the mine’s surface buildings now; how a restored manor sits against a working village.
The valley #
Jezersko is a dead end. The Kokra comes down a narrow valley and stops at a wall of peaks, and the only ways on are up and over. Six hundred-odd people; until 1919 it was administered from the far side of the mountains, from Bad Eisenkappel in Carinthia. The village was a health resort on the strength of its air — an eye tuberculosis hospital took the cure seriously — and the mineral spring, Jezerska slatina, was written up in the seventeenth century and poured with meals in the hotels while there were hotels.
Travellers have been put up here since the sixteenth century. Tourism peaked between the wars, mostly Czech, then fell away after 1945.
The village reads as neat and slightly shrunken — timber and plaster, geraniums, wood stacks.† The Planšarsko jezero pond is heart-shaped and glacial. Above the village, on the slope toward the pass, stands the church of sv. Andrej.
Camping: a field at Zg. Jezersko 124, twenty tent pitches, a row of hard standings, an outdoor kitchen. kamp-jezersko.si
Prompts: what the village sounds and smells like in use; what a shrinking alpine village’s summer consists of.
The kasarna #
Two hundred metres off the pass road, up a track, past the church, in the courtyard of the Jenko farm: a stone building much too big for a farmyard, two storeys, Renaissance in a peasant idiom. Built before 1569 as a hospital in the old sense — a lodging house for carters taking goods over to Carinthia. Men slept here with their horses and wrote on the walls. The signatures are still there, dated 1573 to 1575, scratched into the plaster of an inner room.
It got the name kasarna, barracks, later, probably for no better reason than that it looks like one — or for the Austrian soldiers who held this frontier against Napoleon’s troops at Zgornje Fužine.
It is empty now except as a museum: farm tools and household goods, a room on the valley’s mountaineering history. A protected monument since 1949 and in good order — four and a half centuries of the same building in the same yard, unaltered.
The pass road runs past the bottom of the track. From the courtyard the border is a kilometre and a quarter uphill.
Prompts: the wall inscriptions; who keeps the museum and when it opens; what the farmyard is doing around it.
Leaving the road #
The pass road switchbacks toward the saddle and most traffic stays on it. The way on foot leaves it early, on a cart track that cuts away east and climbs through the trees to the same place by a different line. Above, the road is audible and then not.†
Three hundred metres over a kilometre and a quarter — steep, but short, twenty-five or thirty-five minutes of steady work. The track is grassed in the middle, rutted at the edges, and the trees thin as it rises.†
At the top is the saddle, 1218 metres, a small chapel, a viewpoint, the road arriving from the other side. Austria and Slovenia meet here without ceremony: no booth, no barrier, no gate, a sign in two languages and then the sign in the other language.
The ridge #
The road goes down into the Vellach. The track does not.
North of the saddle the ground lifts onto the border ridge and the path goes up around Koroški Storšič to the Kepp, a grassy saddle at 1633 metres with signposts — 415 metres above the pass, so the crossing costs more climbing after the border rather than less. Waymarks change at the line: Austrian paint, Austrian convention.
High open country, limestone and mountain pine, long views into Carinthia, weather arriving from the north without warning.† Afternoon brings cloud off the peaks and thunder in it.†
Below the Kepp the path drops into the Ebriach valley, hours of descent through spruce, a track, an inn called Kovač, and the Eisenkappler Hütte above it with beds and a stove and a wall of photographs of the Kamnik Alps with the peaks named on them.
Prompts: the Kepp and the ridge in poor weather; the Ebriach valley’s farms and who lives there.
Down to the Drava #
The valley road runs down through Gallizien, lanes and forest between scattered farms, then the country flattens into the Jauntal. Stein im Jauntal has a fortified church on a knoll and, a kilometre on, Tainach-Stein station on the Drava line.
The walking is over.
What a traveller notices #
Nobody stops anyone at the border. Both sides are inside Schengen, so crossing on a track is ordinary rather than a caper. Austrian police run occasional roadside checks near the summit — a car pulled onto the verge, a torch, documents, a few minutes — but they sit on the road, not on the tracks. A passport turns a conversation into a short one.
Nobody much minds a tent in Jezersko, and the municipality has not joined Bled and Kranjska Gora in banning them.
The pass road is a summer road. It opens late in May and shuts with the first serious snow in November, and there is no tunnel under it.
Part two — Austria to the cave #
| Leg | Transport | Change at | Crossing | Risk | ~Cost pp |
|---|---|---|---|---|---|
| Tainach-Stein → Klagenfurt | regional rail, Drava line | – | – | low | €3–4 |
| Klagenfurt → Wiener Neustadt | rail | Klagenfurt | – | med | €20–30 |
| Wiener Neustadt → Wien Floridsdorf | rail, S-Bahn | Wiener Neustadt | – | high | €6–9 |

| Trnava → Žilina → Poprad | rail | Žilina | – | med–high | €10–12 |
| Poprad → Kežmarské Žľaby | bus | – | – | low | €1–2 |
| Kežmarské Žľaby → valley head | foot, blue waymark | – | – | low | €0 |
| Below Skalné vráta → cave | foot, unmarked | – | – | med | €0 |
€50–70 a head, cash, Slovak legs in small denominations.
The two hard points. Austria has run temporary controls at the Slovak border since October 2023, extended to 15 March 2027, and they are border-area controls — checks can sit inland, not only on the line. Take the R81, which terminates at Marchegg, rather than the REX8 through to Bratislava: a dead-end train at a dead-end station is a different arrival from a corridor. Board at Floridsdorf rather than Hauptbahnhof if timing allows. Nothing crosses the Morava by car at Marchegg — the bridge is foot and bicycle.
The route deliberately misses Bratislava. Vysoká, then Zohor, then north to Kúty, then east on trať 116 through the Záhorie. Trnava is where the line rejoins the main corridor and where the crowds start.
The valley #
Dolina siedmich prameňov — the Valley of Seven Springs. 49.22094 / 20.27949. The easternmost valley on the southern side of the Tatras, small, cut into the Belianske Tatry, drained by the Čierna voda — the Black Water — which runs down it to the Poprad.
The head of the valley is a natural amphitheatre walled in limestone, with Skalné vráta, the Rock Gate at 1619 m, standing in the wall as a shaped opening, and Bujačí vrch above it at 1946 m. The slopes are rounded and flower-rich; the valley is called the botanical garden of the Tatras, and in June that is not a marketing line.
Chata Plesnivec sits in the upper valley at 1290 m, the only building in the Belianske Tatry, under the walls. No booth, no fee, nobody counting — but the hut is staffed in season and has a window onto the slope.
Route keeping #
The valley is served by waymarked trail, and the markings are the route:
- Blue from Kežmarské Žľaby, and separately from Tatranská Kotlina. Take the Kežmarské Žľaby side, in from the west under the Stežky slopes.
- Yellow from Čierna voda and from the hut.
- Green from Veľké Biele pleso, over the saddle.
Follow blue. The stream is the handrail: keep the Čierna voda on one side and the marks on the trees, and the valley does the navigating. The amphitheatre is the aiming point from the moment it comes into view and Skalné vráta is the landmark to fix on — the gate in the wall reads from a long way down and pulls the eye.
They leave the blue below the walls and climb the Bujačí flank. Everything above the last waymark is unmarked; route keeping from there is contour and memory, the gate behind them as a bearing, the stream below as a fall-line.
Past the hut the trail carries on to Kopské sedlo and over to Chata pri Zelenom plese — a legitimate through-line if they need to reappear elsewhere.
Prompts: what the Čierna voda sounds like in a small walled valley; where the waymark paint stops; how the Rock Gate reads from below at different light.
The cave #
Nenápadná diera — “the inconspicuous hole.” One of 132 registered caves in the Belianske Tatry and one of the roughly 130 nobody is allowed into. No trail, no marker, no entry in any list of visitable caves, no published dimensions. The name promises nothing, which is the point: a hole in a slope that a walker passes without breaking stride.
Inside, borrow Alabastrová: 400 metres of passage in a rockfall-and-seepage system, permanent water through the roof, a karst lake and a waterfall, secondary gypsum crusting the walls — the mineral that gives the other cave its name and looks like something spilled and set. Cold, wet, loud. Bats in the roof, and in the deeper dark the noctuid moths that got the other cave closed.
Real detail on Alabastrová: discovered 1830 by a man named Muller, natural monument in 1981, 1390 m up in the Bujačí vrch massif, closed under the fifth degree of protection. sl.wikipedia · register of accessible caves
Prompts: what 400 metres of wet limestone does to sound and to a torch beam; how gypsum crust forms; what a karst lake surface does in still air.
The approach #
The bus runs from Poprad to Kežmarské Žľaby under the Kežmarská Biela voda. The blue marks start there.
The marked trail is legitimate as far as they keep to it. Stepping off below Skalné vráta is trespass in a national nature reserve, in a range whose ridge is shut year-round in any case. One offence covers the leaving of the path and the cave together.
The hut is the risk in this version. Going in early puts them above it before anyone is up.
What is real and what is not #
Real: Nenápadná diera exists and is registered. The valley, the Čierna voda, Skalné vráta, Bujačí vrch, the hut, the three waymark colours and the through-route to Kopské sedlo are documented. Alabastrová’s interior, date, discoverer, protection status and altitude are documented. The seasonal closure and the closed ridge are real.
Not real: the pairing of that entrance with that interior, and the cave’s exact position, dimensions and character.
Background — the Austrian side #
Not route, and skippable. Material for what the country is like to cross.
The line runs the wrong way. Usually you cross out of the familiar into the foreign. Here you cross out of a Slovene-speaking country into one where Slovene is a minority language under German officialdom. Their language doesn’t stop working at the line; it changes status. South of it they were ordinary. North of it they are a category.
The signs are a political object. Bilingual place names in Carinthia were fought over for fifty years — boards torn down in 1972, a settlement only in 2011, Article 7 of the 1955 State Treaty behind it. A name board north of the saddle is the visible edge of an argument, and some are still contested or vandalised. A character reading the Slovene half aloud makes a statement without meaning to.
Language stratifies. In Obirsko and the Ebriach, Slovene is a kitchen language and German is the language of forms, police and the man who owns the forest. Older farmers answer in Slovene and switch if pushed. In Klagenfurt it is a curiosity. The same words are a password in one village and an awkward performance in the next town.
The war is close. April 1942, roughly a thousand Slovene-speaking Carinthian families deported into the Reich. Partisans worked this ground with the farm population as their base, and the Ebriach dead are buried at Bad Eisenkappel. It is eighty years on and the memory is in the farms the way farm memory works — in who married whom, and which family was away for four years. Not a region that thinks of 1945 as deliverance.
The mountain was worked. Hochobir had lead and zinc. The Rainer Schutzhaus above the hut was miners’ quarters before it became a shelter. The hollow is still under the grass, and the alpine-club plaque doesn’t mention it.
The money shows. Bigger farms north of the line, steel-framed barns, gravelled yards, new cars, silage wrapped in clean white rows, larger and more uniform forest, proper forestry roads. Hunting stands, “Privat” on gates, fences. The emptiness is not wilderness, it is managed — a landscape with an owner. Concealing people gets worse; concealing objects gets better, because the institutions are older.
The hut is an institution. Stamps, guestbooks, a register of summits, the conventions of greeting. The Eisenkappler Hütte is a day-trip destination with a toll road and a car park. They walk two days to reach a place Austrians drive to for lunch. That is a small humiliation worth having.
The ending sharpens. They come off the mountain into the Jauntal, maize and railway, where the village school is bilingual and the Propstei ran Slovene retreats from 1929 because the northern Jauntal was still Slovene-speaking. They arrive in Austria and hear their own language from Austrian children, then board a train where nobody speaks it at all.
Appendix — the Burgenland route, not taken #
Kept for reference and usable as material for an argument between characters.
Reasons to prefer it: both borders are field tracks with nobody on them rather than a footbridge; it avoids Vienna, Bratislava and the main-line corridor; it crosses two national parks, the Őrség and the Aggtelek karst.
Reasons against, and the ones that killed it: days longer; Hungary’s police work buses and trains for migration and smuggling, so the middle traverse is the most exposed ground of any version; the Székesfehérvár interchange sits furthest from any border with the most uniformed presence.
Route: Ebriach → Bad Eisenkappel → Völkermarkt → Lavamünd → over the Soboth → Deutschlandsberg → Feldbach → Güssing → Heiligenbrunn → foot crossing, field track → Pinkamindszent → Őrség → Szombathely → Sárvár → Celldömölk → Veszprém → Székesfehérvár → Salgótarján → Aggtelek → Green Border trail, 7–9 km → Domica → Kečovo → Plešivec → Rožňava → Poprad.
Austria’s temporary controls on the Hungarian border run to 15 March 2027, same as the Slovak line. The Green Border trail is waymarked green T on the Hungarian side and green diagonal bar on the Slovak.
Treat as unverified #
- The cart track over the Seeberg. One account only.
- The Kepp and Ebriach line. Same walker, who went off waymarks with a GPS.
- The Eisenkappler Hütte. Beds asserted on that one account; mid-June opening unknown.
- All Austrian coordinates from the Kepp onward.
- Nenápadná diera’s position. No source.
- Land access on both descents.
Still to pin down #
- A reason for Idrija that is not convenience.
- What the kasarna museum looks like inside.
- Whether R81 and S1 still serve Marchegg after the 2024–25 works.
- Whether the Zohor–Záhorská Ves line still carries trains or has been bus-replaced.
- Where Austrian checks sit at Marchegg.
- Whether any descent crosses restricted land.
Details
- Route choice settled. Marchegg, not Burgenland. The Burgenland version stays in the appendix as argument material only.
- Valley settled. Dolina siedmich prameňov. Monkova dolina was the alternative and was rejected for having a fee booth at the mouth and a register of faces.
- Cave settled. Nenápadná diera as entrance, Alabastrová’s interior borrowed. Do not propose other caves without reason.
- No papers is a premise, not a detail to solve. Do not have them acquire documents.
- The Tatras are the destination. Poloniny was considered earlier and dropped.
- Register and level of detail settled. Descriptive, not a walking guide. No timetables.
- Idrija’s justification is still open and is the one live gap in part one.

Details
Confirmed means a source says it and it can be relied on.
† marks a line that is mine, not a source’s — atmosphere, inference, how something reads. These are placeholders to be replaced with better description, not facts to repeat as though verified.
Approximate and indicative mean deduced. Check before use.
When filling detail, work outward from the confirmed lines and replace the † ones. Do not treat the flagged material as established.
