Acknowledged as one of the most spectacular waterfalls in Slovenia, Boka is the enormous threshold of waters descending from the Kanin mountain range. As such, late spring happens to be the best time to visit: when the thick snow is melting, up to 100 tons of water per second falls first 106m freely, then a further 30m on an incline. It is visible from a bridge on the Kobarid-Bovec road (near Žaga). A footpath from the road leads to the source of the waterfall, which takes about an hour and a half to reach.
