Mostnica Gorge: walking the ravine the river carved itself
Just above Lake Bohinj, the Mostnica river spent thousands of years carving its gorge. This guide covers the walk: the route from Stara Fuzina, the entry fee, the Voje Valley and the waterfall at the end.
Everyone at Lake Bohinj looks at the water and the mountains. Walk ten minutes further to Stara Fužina and you find something at least as remarkable: a gorge where the Mostnica river has cut its way through the limestone, leaving whirlpools and bathtubs in stone so smoothly polished they look sculpted. Emerald water, two kilometres of it, and a waterfall waiting at the end of the valley.
This guide covers how to walk the trail, what you see along the way, whether it works with children and what the entry fee is.
The Mostnica spent thousands of years working on its gorge. Walk alongside it and time seems to slow down.
What makes the Mostnica Gorge so special?
The gorge lies inside Triglav National Park, just above Stara Fužina, a village worth a look in its own right for its distinctive hay racks. The Mostnica has cut down as deep as twenty metres here; at the narrowest points the walls almost seem to touch. The most famous piece of sculpting is the Slončk, the elephant: an opening in the rock that the water has carved into the shape of a small elephant.
Along the way you see how a gorge like this forms: the water drags stones along, they spin in the eddies and grind perfectly round bowls into the rock bed, known as korita in Slovenian. On bright days the water in those bowls shifts from emerald to almost turquoise, depending on depth and light.
What sets the Mostnica apart from the better-known gorges is the calm. No timed entry, no coaches, no fences all the way to the entrance. Just a path, a few stone bridges and the sound of water. For comparison: Vintgar Gorge near Bled is more spectacularly engineered, but it works with time slots and draws many times more visitors. Here, on a weekday morning, the pools can be yours alone.
Stara Fužina: the village where you start
Take a quarter of an hour for the village itself, before or after the walk. Stara Fužina is one of the best-preserved villages in the Bohinj valley, with the characteristic double hay racks (toplarji) you barely see anywhere else, and the small Oplen House museum showing how people lived here well into the last century. The gorge begins at the edge of the village: this is not an attraction you drive to, but a walk that sets off from the everyday life of the valley.
How to walk the trail
The classic route starts at the stone Hudičev most (Devil's Bridge) just above Stara Fužina and follows the gorge upstream:
- Part 1, the gorge: from the bridge it takes about an hour to pass the finest pools and the Slončk. The path switches banks over small stone bridges and is easy to follow.
- Part 2, the Voje Valley: after the gorge the landscape opens into a green alpine valley with meadows and a handful of farms. Halfway along stands Koča na Vojah, a mountain hut with a summer terrace: the logical place to stop.
- Part 3, the waterfall: at the head of the valley the Mostnica drops more than twenty metres. It is at its most impressive in spring and after rain.
Allow three to four hours there and back for the whole route, including breaks. If you only want to see the gorge, you are back in the village within an hour and a half.
How do you get there?
Stara Fužina is a five-minute drive (or a forty-five-minute walk) from Ribčev Laz, the main village on Lake Bohinj. Park in the marked spaces in the village and follow the signs for Korita Mostnice towards the Hudičev most. In high season the car park fills up quickly; come early or take the bus to Stara Fužina.
Is the walk suitable for kids?
Yes, and more so than most gorge walks. The path is wide enough, the railings are where they should be, and the variety keeps attention going: little bridges, the elephant rock, cows in the Voje Valley. From around age five children manage the gorge section themselves; the full route to the waterfall asks for a bit more stamina. A push chair will not make it here, so bring a carrier for the smallest ones.
When to go to the Mostnica Gorge
The gorge is accessible all year, but it is at its best from late spring to early autumn. In May and June the water runs high and the pools are at their wildest; in October the beech forest around the gorge turns golden. After heavy rain the path can be slippery, so sturdy shoes are no luxury. Winter has its admirers too: the entry fee lapses, and in hard frost ice formations hang along the walls. In that season, check with the tourist office in Bohinj first to see whether the path is passable, and expect slippery stretches.

Still have energy afterwards? Lake Bohinj is around the corner, and if you like huts and high places, our mountain hut guide covers the routes that climb into the mountains from here.
And if the combination of gorge and waterfall leaves you wanting more: the Martuljek waterfalls near Kranjska Gora are the spectacular northern counterpart to this walk, and our full guide covers them. On the way there, the Peričnik waterfall in the Vrata Valley is worth the stop too: one of the few waterfalls in the Alps where the path takes you behind the curtain of water.
