From Kobarid, follow the road leading to the Napoleon Bridge. Just before the bridge, turn left towards Kamp Lazar. There’s a large (free) car park just before you reach the campsite.
(S/E) From the car park, follow the road towards the campsite. Walk past reception and, at the end of the road, turn right onto the steps leading down to the Soca.
(1) Cross the Soca via the 50-metre-long footbridge (which is about 20 metres high!) then turn left towards Slap Kozjak.
Follow this wide, shaded path to a small bridge, under which flows the river originating from Slap Kozjak.
(2) Carry on straight ahead, following the river along the right bank. A few minutes further on, two small bridges take you closer to the waterfall, before you reach a jetty fitted with a handrail from which you can admire the waterfall and its pool from above.
(3) If you’d like to have a swim or get closer to the pool, you’ll need to retrace your steps to the foot of the jetty, take off your shoes and wade up the stream barefoot (the water will come up to the bottom of your thighs in summer) and settle down on the left-hand side on a ‘beach’ of large pebbles!
For the return journey, follow the same route as on the way there (S/E).
