The Krn Lakes are stunningly green and heartbreakingly beautiful—it’s no coincidence. Nestled deep in the heart of Triglav National Park and part of the majestic Julian Alps, they sit high above the Soča Valley. The lakes are surrounded by magnificent grassy slopes beneath towering peaks: Velika Baba (2,013 m) to the northeast, Mali & Veliki Šmohor (1,939 m) to the south, and Krn summit (2,244 m) to the southwest.
- Hiking Mission: Velika Baba (2,013 m) Peak & Veliki Šmohor (1,944 m)
- Starting Point The adventure begins at Dom Dr Klementa Juga v Lepeni mountain hut, right above the Soča canyons in the Lepena Valley.
Access to the Starting Point
Between Trenta and Bovec, turn off near the village of Soča onto the road to Lepena. The fully paved, though narrow, road stretches about 6 km to the parking lot at the hut. We approached from the Kobarid–Bovec side. While the road is tight, it’s wide enough for medium-sized buses, and the parking lot offers ample space for cars and buses, with a convenient turning area.
The Dom Dr Klementa Juga v Lepeni hut sits at 700 m in the Lepena Valley. Named after the Slovenian alpinist, philosopher, and writer Dr Klement Jug—renowned for his influential works on alpinism—the hut was rebuilt in 1953 from a former military building. It proudly holds both Family Friendly and Environmentally Friendly certifications.
Route Description
Since we combined several routes into one full hiking day around the Krn Lakes, I’ll break it down step by step.
A gentle start from Dom Dr. Klementa Juga v Lepeni hut to Velika Baba
After parking near the hut, we geared up: hiking boots, t-shirts, walking trousers—nothing more needed (though trekking poles are handy if you use them). We started at 7:37 a.m.
From the hut, follow the wide, marked path toward the Krn Lakes. After a few minutes, the trail splits: the left branch is steeper and more direct, the right is flatter and slightly longer (better for kids or elderly hikers). We chose the left path, but both paths climb through a shady forest and cross several times before rejoining near the upper cable car station. There are wooden steps along the way. After about 30 minutes, you get your first glimpses of Lepena Valley through openings cleared for the cable car.
After nearly 2 hours (around 9:23 a.m.), we reached the upper station of the freight cable car (used for supplying Dom Pri Krnskih Jezerih hut). From there, continue along the same wide path, which climbs moderately steeply. Soon you’ll pass the annual snow measurement point (checked every April). The path then descends slightly to a less obvious crossroads. Turn left (marked “Velika Baba”) onto a faint path that drops gently over a small meadow. Straight ahead leads to Dom Pri Krnskih Jezerih hut (10 min).
The Velika Baba trail enters a short forest strip, then emerges onto a floral, mostly exposed stone path that climbs gently through tall grass. After a few minutes, you reach scree slopes below the peak. The route turns right, then ascends transversely across the slopes with gorgeous views of Krn Lake.
A short, steep section through pine trees brings you under the vertical walls of Velika Baba. The path follows the slope (partly grassy now) to a small valley between Velika Baba (left) and Velika Montura. Here, there’s a minor orientation loop with marked and unmarked trails. Turn left toward Velika Baba (a few steps down), then climb a grassy/stony slope dotted with dwarf pine. The final section steepens quickly, leading to the summit of Velika Baba (2,013 m), a fantastic lookout.
We reached the top at 11:21 a.m. The panoramic views are incredible: neighbouring Julian Alps peaks like Triglav, Jalovec, Krn, Lanževica, Tolminski Kuk, Vogel, Vrh Nad Škrbino, and more. The mountain directly opposite looked especially tempting—half our group planned to climb it that day!
Descent: Velika Baba → Dom Pri Krnskih Jezerih
We descended the same way back until reaching the crossroads near the hut. From the grassland area coming from Velika Baba, turn left at the freight cable car sign. Continue down to the next crossing, then left on the footpath to the hut (a few minutes). (Staying on the road skips the hut.)
We arrived at Dom Pri Krnskih Jezerih at 1:06 p.m.
Dom Pri Krnskih Jezerih Lodge
Perched above Dupeljsko Jezero and just a 15-minute walk from the hidden gem of Krnsko Jezero, this picturesque, welcoming hut is one of Slovenia’s most visited mountain lodges. While the building itself—including its winter room—doesn’t offer direct views, the surrounding green woods more than make up for it, offering the peaceful scenery we love. The hut is open daily throughout the summer, making it an ideal stop for hikers exploring the area.
Krnsko Jezero – Krn Lake (1,391 m)
The path to the lake winds over pastures filled with the soothing sound of cowbells from those classic Alpine cows (you know, the ones on Milka chocolate wrappers—when I saw them, I half expected one to be missing its chocolate!).
Most adventure seekers extend the trip here. Krnsko Jezero is Slovenia’s largest high-mountain lake: 300 m long, 150 m wide, up to 18 m deep, teeming with small fish. Its green-gold colour is mesmerising, framed by dramatic peaks—an inspiration for every hiker (and yes, even goats seem to love it).
Formed by ancient glaciers beneath Krn summit (no glaciers remain today), the lake’s beauty endures thanks to its pristine alpine setting. We soaked in stunning views toward Krn peak and breathed in that crisp mountain air.
Swimming is prohibited to protect the fragile ecosystem (already impacted by introduced fish). My phone battery died from too many photos, but the GPS track captured the rest of our day. If you’re coming from about 3 hours away (like us from Istria, Croatia), Velika Baba + Krn Lake makes a perfect full-day trip. Just relax in this stunning alpine jewel beneath Krn peak.
But my “want-more” colleagues called, so I joined them for Veliki Šmohor!
Krn Lake → Veliki Šmohor (1,944 m)
From the lake, head back along the winding path, joining the route around the hut. Pass the shepherd’s hut to the next crossroads, then right toward Šmohor (follow signs).
After a steep start, the narrow path opens views to Jalovec. Cross a small meadow, enter undergrowth, then join an old, partly overgrown military mule track from WWI. Climb moderately over increasingly open slopes, passing many Isonzo Front remnants (trenches, iron tools, etc.).
Under steep walls of Mali Šmohor, watch for falling rocks (helmet recommended—we didn’t have one). Cross scree, turn left onto grassy slopes, then ascend to the ridge. Bypass Mali Šmohor (right, 3 min) and continue left along the ridge slightly downhill to a saddle. Straight on a scenic, faint path to the summit.
We reached Veliki Šmohor at 3:10 p.m.—breathtaking views of Krn on one side, Jalovec and Triglav on the other.
(Alternative: Lepena → Dom Pri Krnskih Jezerih ~2 hours; hut → Veliki Šmohor ~2.5 hours; total hiking ~4.5 hours.)
Descent from Šmohor
Same route back: past pastures, the hut, then down via the cable car path to Lepena. We reached the hut at 6:15 p.m.
🐐Trek Goat tip. Both peaks above Krn Lake can be done in one day—as we proved! But if you’re not a pro trekker (I’m definitely not), take it slow with breaks at the lake or hut. In summer heat, do one peak in the morning and the other in the afternoon before sunset. After such a long day, it’s wise not to drive far—stay nearby if possible.

Tips for slow travel to Krn Lakes
- Starting point: Dom Dr Klementa Juga v Lepeni (700 m).
- Best time to go: Late spring through early autumn.
- Route difficulty: Easy to moderate.
- Huts: Open in the summer months, offering food and drinks
- Bring: Water, snacks, sun protection, and a camera—but don’t live through the lens.
- Respect: No swimming in the lake; help protect the ecosystem
- Optional: Just Krn Lake. If time is short or you prefer a slower pace, hiking only to Krn Lake and back makes a perfect day tour. You’ll experience forests, history, pastures, and alpine tranquillity—without the pressure of a summit.
- Conclusion. This hike into the heart of the Julian Alps is pure magic. Slow down, breathe it in, and let the mountains speak. Here, it’s not about how far or how high—it’s about how deeply you breathe, how often you pause, and what you notice when you’re unhurried. Krn Lakes, embraced by silence and towering peaks, are a gentle reminder: slow is not less. Slow is more.
