About JK17
JK17 is a 23.2 km hiking route in Slovenia. It climbs roughly 45 m (148 ft) along the way. Most people take around 5 hr 9 min at a comfortable pace, plus stops. This is a demanding day. The climbing is sustained and the descent is long enough to punish tired knees.
Above the treeline the route crosses open pasture, at its most colourful in early summer. The higher sections open out completely, with ridgelines stacking into the distance on clear days. Most people walk it in stages, using the waymarking and accommodation built up along the corridor.
Start and finish are in different places, which means public transport or a second car is part of the planning. The route is waymarked and marked on the ground with its own symbol, so navigation is straightforward in good visibility.
It walks well across three seasons, with spring and autumn offering the best combination of light, temperature and quiet paths. The nearest town of any size is Udine, about 32.5 km away, which is where most people base themselves. The route is maintained by Alpine Vereine/Julius Kugy Forum: Kärnten, Slovenija und Friuli-Venezia Giulia I-Adresse: https://www.alpenverein.at/kaernten/.
In short, JK17 suits fit hikers with a habit of long days and an eye on the forecast. Dog access is not formally recorded here, so check locally before bringing one.
Plan around this route’s details
- Start, finish and return
- The recorded 23.2 km line has different endpoints. Confirm travel from the finish before setting out; that return journey is additional to the mapped route.
- Climbing in context
- The recorded ascent averages approximately 2 m of climbing per kilometre across the whole route. This is climbing density, not trail gradient: climbs and flatter sections may be unevenly distributed. Recorded descent totals 45 m and also needs time in your plan.
- What needs a separate check
- This record does not establish surface, dog access, wheelchair access. Check any of these that affect your group. Current closures, access arrangements and transport are not verified by the route line.

Your walking-time scenario
Adjust the example pace and allowances to explore your own plan. This calculator uses your inputs, so it may differ from the directory’s headline estimate.
Calculated walking time including your allowances
6 hr 24 min
349 min for distance + 5 min for ascent + 30 min allowance.
Formula: distance ÷ pace × 60 + ascent ÷ 100 × climbing allowance + stops. Travel to and from the route is additional. Terrain, descent, weather and navigation are not modelled. These results do not establish route suitability. Read the time-planning guide.
Recorded route measurements
The route is normally walked in the direction described below. The gradient is spread evenly, so there is no single section that dictates your pace. The upper section is where the route earns its reputation, and it is also where weather changes fastest. Because the finish is away from the start, check return transport before committing to the second half.

Tips from the trail
- Start at first light. A long day is far more pleasant when you are not racing the sunset on the descent.
- Aim for april to october for the most reliable conditions.
- Leave nothing behind, including fruit peel, and stay on the marked line to protect the ground either side.
Warnings
- This route is long and sustained. Turn back early rather than late if the weather closes in.
- Outside the main season expect snow, ice or closed access on the higher sections.
Safety
Emergency services in Slovenia are reached on 112. Tell someone your route and expected finish time before you set off, particularly if you are walking alone. Mobile coverage is generally usable along this route, but do not rely on it as your only plan. If the weather deteriorates, descending the way you came is almost always the safer option.
What to bring
- Comfortable, broken-in hiking shoes or boots
- Weatherproof jacket
- At least 1.5 litres of water
- Offline map and compass
- Head torch and spare battery
- Extra warm layer
- Sun hat, sunglasses and high-factor sun cream
- Real food, not just snacks
- Small first aid kit including blister plasters
Photography
Shoot the first hour after sunrise from the higher ground: the low angle picks out every ridge and the valleys still hold mist. Take the shot on the way out. Conditions rarely improve by the time you come back past. A wide lens captures the scale, but a short telephoto is what turns a good view into a photograph.
