Nestled in the heart of Triglav National Park, near the glacial Lake Bohinj, lies one of Slovenia’s most picturesque and rewarding hiking routes – the Trail to Mostnica Waterfall. This scenic trail follows the crystal-clear Mostnica River through a stunning gorge and across the peaceful alpine Voje Valley, offering a perfect combination of nature, geology, and serenity. It’s not just a hike – it’s a full sensory experience, ideal for nature lovers, families, and casual walkers alike.
Location and How to Get There
The trail begins in the charming alpine village of Stara Fužina, located just a few kilometers from Lake Bohinj in the Gorenjska region. It is easily accessible by car or public transport from Bled or Ljubljana. There’s a designated parking area near the old military barracks in Stara Fužina (paid during the tourist season).
From there, a short walk leads to the entrance of the Mostnica Gorge. Visitors are required to pay a small entrance fee (around €3–4 for adults), which goes toward the maintenance and conservation of the area, as it lies within Triglav National Park – the only national park in Slovenia.
Trail Overview and Features
The full round-trip trail is approximately 12 kilometers (7.5 miles) long, with a gentle incline suitable for all age groups and fitness levels. Hiking the entire route takes about 3 to 4 hours, depending on pace and time spent at scenic spots. The most common destination is the Mostnica Waterfall (Slap Mostnice), located at the end of the valley.
Mostnica Gorge
The first and most dramatic part of the hike takes you through the Mostnica Gorge, where the river has carved a narrow limestone canyon over thousands of years. The gorge features vertical walls up to 20 meters high and sections just a meter wide, with swirling pools, rapids, and cascades along the way.
Wooden footbridges and railings provide safe access and panoramic views of the gorge’s most iconic spots – including the famous Elephant Rock, a large natural rock formation that strikingly resembles an elephant’s head. This part of the trail is especially popular with photographers and nature enthusiasts.
Voje Valley
After exiting the gorge, the trail opens up into the tranquil Voje Valley, an expansive alpine meadow surrounded by the peaks of the Julian Alps. The valley is especially beautiful in late spring and summer, when wildflowers bloom and cattle graze freely. The peaceful setting offers a perfect place to rest, take photos, or enjoy a picnic.
In the middle of the valley stands the cozy mountain hut Koča na Vojah, a great spot to grab a local meal – from hearty soups to homemade apple strudel and traditional cheeses. The hut is open during the warmer months and is a popular resting point.
Mostnica Waterfall
Continuing for another hour from the Voje Valley, the trail leads to the Mostnica Waterfall, a 20-meter-high (65 ft) waterfall tucked in a forested corner at the valley’s end. The final stretch of the path becomes slightly steeper and more rugged, but it remains manageable for most hikers.
A wooden observation platform allows safe viewing of the waterfall, which is particularly impressive in spring and after heavy rain. The thunder of cascading water and the lush green surroundings make it a rewarding finale to the hike.
Natural and Cultural Highlights
The Mostnica area is part of the Natura 2000 ecological network, recognized for its diverse and rare plant and animal species. The river is home to native brown trout, and the surrounding forests shelter deer, foxes, squirrels, and a variety of bird species.
The trail also showcases fascinating glacial and karst formations, including eroded limestone, potholes, and fossils. These geological features make the area popular among science students and nature interpreters.
On the cultural side, visitors can learn about traditional alpine life by visiting the Dairy Museum (Planšarski muzej) in Stara Fužina. This small but informative museum displays the history of cheese-making, shepherding, and rural life in the Bohinj region.
Best Time to Visit
The trail is open year-round, but the best time to visit is from April to October. In spring, snowmelt feeds the river, making the gorge and waterfall especially powerful. Summer brings mild weather and clear skies, while autumn colors turn the valley into a golden wonderland.
Winter visits are possible but require caution due to ice and snow. Some sections may be slippery or temporarily closed, so proper footwear and warm clothing are essential.
To avoid crowds, it’s recommended to start your hike early in the morning or in the late afternoon, especially during peak tourist months (July and August).
Tips for Hikers
- Footwear: Although the trail is not technically difficult, wearing sturdy, waterproof hiking shoes is highly recommended due to rocky and potentially wet terrain.
- Food & Water: While there are refreshment options along the way, it’s wise to bring a water bottle and snacks, especially outside the summer season.
- Safety: Stay on marked paths – the riverbanks can be slippery and dangerous.
- Respect Nature: As you’re in a protected area, follow park rules – don’t litter, pick plants, or disturb wildlife.

The Trail to Mostnica Waterfall is a perfect example of Slovenia’s natural beauty – unspoiled, accessible, and deeply enriching. Whether you’re looking for a peaceful nature escape, a family-friendly hike, or a scenic adventure through canyons and alpine meadows, this trail delivers it all.
From the dramatic Mostnica Gorge to the idyllic Voje Valley and the thunderous waterfall at the end, every step of this journey is filled with wonder. It’s a must-see for any visitor to the Bohinj region – and a reminder of the quiet power and elegance of nature.
