JK07

The Julius Kugy Alpine Trail (JK07) is a 720 km circular long-distance route through the Southern Alps of Austria, Slovenia, and Italy, completed in 30 stages with 45,000 m of total elevation gain. Opened in 2019 by the Alpine clubs of all three countries, it traverses Triglav National Park, the Kamnik-Savinja Alps, and the Carnic Alps in one continuous loop, starting and finishing in southern Carinthia.

About the Julius Kugy Alpine Trail

The trail honours Dr. Julius Kugy (1858–1944), a Trieste-born lawyer, botanist, and mountaineer who devoted four decades to exploring the Julian Alps and became the defining voice of the Alpe-Adria mountain culture. His 1924 memoir From the Life of a Mountaineer remains essential reading for anyone planning time in these peaks.

The route was formally agreed at the 55th Three-Country Meeting in Mojstrana in June 2019, when the Austrian Alpine Club (ÖAV-Landesverband Kärnten), the Slovenian Alpine Association (PZS), and the Italian Alpine Club for Friuli-Venezia Giulia (CAI-FVG) linked their existing regional trails into one cohesive circuit. Trail signage and infrastructure were installed through 2021–2022. In 2023 the project was designated an Innovative Flagship Tourism Project by Austria’s Federal Ministry for Labour and Economy — a recognition shared by fewer than a dozen initiatives across the country. In 2024, a bronze peace sculpture was installed at Wolayersee, inscribed with “Blessed are the peacemakers,” at the alpine lake on the Austria–Italy border where WWI alpine fighting once took place.

The path breaks down as follows: 290 km of mountain footpaths, 160 km of gravel tracks, 95 km of natural terrain, 90 km of asphalt, 60 km of road, and 3 km of secured alpine climbing sections. The highest point reaches 2,401 m; the lowest dips to 198 m. At the official pace the route takes 270 hours of walking — roughly 9 hours per stage over 30 stages. Beyond the main circuit, 8 official extensions and 60 connecting trails allow the JK07 to be walked in sections without retracing steps.

For context on how the JK07 sits within Slovenia’s broader trail network, the 2026 guide to hiking trails in Slovenia covers shorter routes that work well as building-block trips before committing to the full circuit.

Route Overview & Stages

The circuit starts and ends at the Bertalhütte (Borovščica Cottage) near Feistritz im Rosental in southern Carinthia, Austria. The standard direction is clockwise: east through the Karawanken into Slovenia, then west through the Kamnik-Savinja Alps, south through Triglav National Park and the Soča Valley into Italy, and finally north through the Carnic and Gailtal Alps to close the loop in Austria. At an average of 24 km per stage, daily elevation varies widely — from a gentle 600 m on valley-floor connectors to over 1,800 m on the alpine crossing days near Triglav and the Wolayersee.

Highlights & Points of Interest

• Triglav National Park (Stages 10–11): Slovenia’s only national park covers 838 km² of the Julian Alps and hosts alpine ibex, chamois, and the endemic Triglav buttercup (Ranunculus traunfellneri). The trail routes through the Triglav Lakes Valley — a chain of seven glacial lakes at elevations between 1,300 m and 1,996 m — before climbing to Prehodavci pass at 2,071 m.
• Logarska Dolina (Stages 5–6): This 7.5 km glacial valley at 838 m is enclosed by walls rising to over 2,000 m and fed by the Rinka waterfall, which drops 106 m. Entry to the Landscape Park is free on foot; a €5 vehicle fee applies only to those arriving by car.
• Wolayersee Peace Monument (Stage 23): The alpine lake at 1,961 m sits directly on the Austria–Italy border, above terrain where WWI alpine warfare was fought at altitudes exceeding 2,000 m. The bronze peace sculpture installed here in 2024 — blessed jointly by Austrian, Italian, and Slovenian clergy — makes this one of the trail’s most affecting overnight stops.
• Soča Valley & Kobarid (Stage 13): The Soča River’s emerald-green colour comes from dissolved limestone and glacial silt. The Kobarid Museum covers the 1917 Battle of Caporetto (Twelfth Battle of the Isonzo), where German-led forces broke through Italian lines in one of WWI’s most dramatic tactical reversals. The museum won the Council of Europe Museum Prize in 1993.
• Potočka Zijalka Cave (Stage 4): A karstic cave at 1,700 m on the Olševa plateau, excavated in the 1920s and yielding Pleistocene cave bear bones dating back over 30,000 years. The ascent from Bad Vellach (Bela) gains roughly 900 m of vertical relief — one of the steeper early days on the Slovenian section.
• Nassfeld / Naßfeld Area (Stages 27–28): The Nassfeld ski resort operates as a summer hiking hub from late June through September, with cable car access, mountain restaurants, and a dense network of waymarked trails that several JK07 stages use as a high-altitude corridor above 1,500 m.
• Sauris / Zahre (Italian Section): A village at 1,200 m in the Carnic Alps where Friulian and Cimbrian German coexist — a linguistic pocket tracing to 14th-century Bavarian settlement. The Sauris reservoir provides a dramatic overnight backdrop between Tolmezzo and the return north toward Austria.
• Dobratsch Summit House (Stage 29): At 2,166 m on the Villacher Alpe, the summit restaurant commands a panorama stretching from the Dolomites south to the Triglav massif — a full-circle view that closes out the circuit one stage before the return to Bertalhütte.

Practical Information

Best Time to Hike

Mid-June to mid-September is the reliable window for the full circuit. Snow clears from the highest passes (above 1,800 m) by mid-June in average years; by mid-September the first autumn snowfall often returns to the Julian Alps above 2,000 m. July and August are the busiest months — huts in Triglav National Park run at near-full capacity and booking 4–6 weeks ahead is standard practice. The first two weeks of September combine stable high pressure, cooler temperatures (8–16 °C at altitude), and significantly fewer hikers — the best trade-off of conditions and quiet. Afternoon convective storms are most frequent July–August across all three countries; an early start by 6:00–7:00 keeps the exposed ridgeline sections clear of weather.

Accommodation

The JK07 is supported by 17 official mountain huts managed by the ÖAV, PZS, and CAI alpine clubs, supplemented by B&Bs, guesthouses, and small hotels in the towns along the route. Hut dormitory beds typically cost €25–40 per night; private rooms run €45–75. Alpine club membership (ÖAV, PZS, CAI, or any affiliated UIAA club such as the BMC or DAV) cuts hut fees by approximately 50% and pays back its annual cost (€45–72 depending on the club) within 2–3 nights. Wild camping is strictly prohibited inside Triglav National Park and regulated in most other sections — use designated bivouac zones or obtain landowner permission in advance. Town accommodation at Mojstrana, Kobarid, Tolmezzo, and Hermagor runs €60–110 per night for a private room, useful as a rest-day base.

Getting There & Back

The conventional start near Feistritz im Rosental is 20 km from Villach Hauptbahnhof, Austria’s key rail junction connecting Vienna (2h 30min), Salzburg (1h 45min), and Ljubljana (1h 20min). A regional bus or taxi covers the final stretch to Feistritz. Klagenfurt Airport (KLU), 30 minutes from Villach by rail, has direct flights from Vienna, Frankfurt, and Zürich. For hikers entering mid-circuit in Slovenia, Ljubljana Jože Pučnik Airport (LJU) connects to most major European hubs, with rail onward to Jesenice (8 km from Mojstrana) via the Karawanken tunnel — a natural entry point for the Triglav-focused section.

Permits & Fees

As of 2026, there is no trail permit or pass required for the JK07. Triglav National Park is free to enter on foot. Logarska Dolina charges €5 per vehicle (foot traffic is free). The main financial planning items are hut fees (substantially reduced with club membership) and the optional official trail guidebook, available from the Julius Kugy Forum for approximately €25.

Gear & Packing List

Thirty stages across three countries with 45,000 m of elevation demands kit calibrated for sustained alpine terrain. These are the decisions that make the biggest difference on a trip of this length:

• Footwear: The secured climbing sections and consistently rocky Slovenian stages demand lateral stiffness and reliable grip on wet limestone. The La Sportiva Bushido III (340 g/shoe) handles the technical ground with a Vibram Megagrip sole while remaining light enough for 30-day daily mileage without undue fatigue.
• Trekking poles: Essential on the steep descents from Triglav Lakes, the Karawanken ridges, and the long Italian descents into valley towns. The Black Diamond Distance Carbon FLZ poles fold to 38 cm and weigh 420 g per pair, making them quick to stow on the scramble sections without adding bulk to the pack.
• Navigation: Cell coverage drops out reliably on the higher Austrian and Italian ridges. A GPS watch loaded with the JK07 GPX track is a practical requirement rather than a luxury. The Garmin Fenix 7X Solar runs up to 22 days in expedition GPS tracking mode — enough for the full circuit without depending on power-bank top-ups at huts.
• Layering: Afternoon thunderstorms are a near-daily risk in July and August. Carry a packable waterproof shell under 300 g, a mid-layer fleece, and a light down jacket for hut evenings above 1,500 m. Even in July, overnight temperatures in alpine huts at 1,800 m regularly drop below 5 °C.
• Pack volume: Between huts you rarely need more than 2 days of food. A 40–50 L pack keeps the carried load manageable; the secured climbing sections become significantly more demanding above 16 kg total weight. For packs under 1 kg, the 2026 ultralight backpack comparison covers tested options suited to a 30-day mountain circuit.
• Water capacity: Springs and streams are frequent through the Slovenian sections but some Austrian and Italian ridge traverses above 1,600 m have no reliable water for 6–8 hours. Carry at least 2 L capacity and a filter or purification tablets for untreated sources.

Anyone considering a compressed itinerary should work through the fastpacking training guide before committing — the via-ferrata sections have a fixed minimum time requirement regardless of fitness, and several Triglav-area stages have no shortcut if weather closes in.

Frequently Asked Questions

How long does it take to complete the Julius Kugy Alpine Trail?

The official walking time is 270 hours across 30 stages, averaging 9 hours per stage. Fit hikers complete the circuit in 30–35 days of continuous hiking. Most thru-hikers budget an additional 5–7 rest days for weather holds and resupply, giving a realistic total of 35–42 days. Section hikers typically allocate 8–12 days per country segment.

Is the JK07 suitable for hikers without alpine experience?

No. With 45,000 m of total elevation, 3 km of secured climbing sections, and stages regularly exceeding 2,000 m, the JK07 requires prior multi-day alpine hiking experience and comfort on exposed mountain terrain. Hikers building toward it should first complete several hut-to-hut alpine weeks or a route like Slovenia’s 600 km national Slovenian Mountain Trail (Slovenska planinska pot).

Which stages pass through Triglav National Park, and is camping permitted?

Stages 10 and 11 pass through Triglav National Park across approximately 50 km, including the Triglav Lakes Valley and Prehodavci pass at 2,071 m. Wild camping is strictly prohibited throughout the park. The standard overnight stop is Dom pri Triglavskih jezerih hut at 1,685 m — book 4–6 weeks ahead during July and August, as it regularly fills to its 60-bed capacity.

Can the JK07 be hiked in individual country sections rather than as a thru-hike?

Yes, and this is the most common approach as of 2026. Eight official extensions and 60 connecting trails are designed for flexible section hiking, with public transport connections at Mojstrana, Tržič, Kobarid, Tolmezzo, and Hermagor. Each country section covers 180–250 km and makes a coherent 12–18 day trip. The Slovenian section — encompassing Triglav National Park and the Soča Valley — is most often chosen as a standalone.

Does alpine club membership make a meaningful financial difference on the JK07?

Significantly. ÖAV, PZS, and CAI members receive approximately 50% off mountain hut fees throughout all three countries. With 30 hut nights at an average saving of €15–20 per night, annual membership — €45 for PZS, €72 for ÖAV — pays back within the first two nights on trail. Members of affiliated UIAA clubs (BMC, DAV, FFCAM) qualify for the same discounts at huts in all three countries.
