    The Boka waterfall pours down a grey rock wall between green slopes near Bovec, in the Soča Valley

    Soča Valley, Bovec

    The Boka waterfall, Slovenia's most powerful

    Facts checked on
    Total height
    144 m (a 106 m free fall plus 30 m)
    Width
    18 m
    Water temperature
    4.5 °C on average

    The Boka waterfall drops 144 m in all, 106 m of it in free fall, and is 18 m wide; the Slovenian Tourist Board calls it the country's highest-volume waterfall. You can see it from the road between Bovec and Žaga, but the viewpoint, a quarter of an hour's walk from the bridge, is worth it, especially in spring and autumn when the flow is strongest.

    What I would do

    You can see Boka from the car, but I'd walk up to the lower viewpoint, which is short and easy. I'd only take the upper path with good boots and without children, because it's very steep and exposed in places.

    Step by step

    1. Park by the bridge

      Stop on the road between Bovec and Žaga, where the fall is already visible from the bridge area.

    2. Walk to the lower viewpoint

      An easy path of about a quarter of an hour leads to the lower viewpoint facing the fall.

    3. Decide on the upper path

      The upper trail is very steep with exposed sections; only take it in good boots and without children.

      Water out of the wall

      Water from the Kanin massif emerges on a rock ledge and plunges 106 m straight down, then another 30, in the middle of a sheer wall.

      Spring and autumn

      With snowmelt and rain it can carry up to 100 m³/s and is at its loudest; in dry summers it drops to about 2 m³/s.

      A grim legend

      Folk tradition says two children out gathering mushrooms killed an old woman who planned to roast them, and her blood turned into the waterfall.

      Between Bovec and Kobarid

      It's on the Bovec to Žaga road, so it fits in on the way between Bovec and Kobarid, with the Kozjak waterfall not far off.

    What the Boka waterfall is like

    Water gathers in the mountains of the Kanin massif and comes to light on a rock ledge. From there it free-falls 106 m and straight afterwards another 30, for a total of 144 m with a width of 18 m. Because it hits the ground so hard, erosion keeps deepening the spot where it lands.

    The flow changes enormously with the seasons. In spring and autumn, with snowmelt and rain, Boka is at its best, loud and very photogenic, while in the dry summer months it shrinks to a trickle by comparison. The water is always cold, averaging just a few degrees.

    When to go: spring and autumn

    The difference between seasons is huge. With snowmelt it can carry up to 100 m³/s, and in dry summers it falls to about 2 m³/s, fifty times less, so the same waterfall looks like a different one depending on the date. Visit at the end of a rainless summer and you may find little more than a white thread on the rock face. The Slovenian Tourist Board recommends not stopping at the roadside but climbing to the lookout point, where you feel the full force of the water.

    The Boka legend

    Folk tradition tells a story that sits oddly with the beauty of the place. A boy and a girl who went up the hill for mushrooms knocked, hungry, at the door of a small house, where an old woman fed them. The boy caught her sharpening an axe outside and plotting to kill and roast them, so he waited behind the door with a stick, struck her and finished her off with her own axe. Her blood turned into the waterfall, which took its name from it.

    Getting to the viewpoint

    It’s easy to spot from the Bovec to Žaga road, between Bovec and Kobarid. On the right side of the bridge a well-marked path leads to a panoramic viewpoint, a short walk away. The agile can carry on at their own risk along a very steep path with exposed sections, which opens up even better views until it reaches a viewpoint above the waterfall itself. The Soča Valley Tourist Board also suggests a longer route linking Boka with the Lipuc bridge. Times and distances are in the table.

    More to see around Bovec

    Boka pairs well with the Kozjak waterfall near Kobarid, which is almost its opposite, small and tucked into a stone chamber, and with Virje, next to Bovec. Falls elsewhere in Slovenia are covered in waterfalls in Slovenia.
