Kamačnik cut its gorge into the Velika Kapela massif and flows into the river Dobra, collapsing with a small waterfall, since it is partitioned by a gap and a lake at the entrance to the canyon. The source of the Kamačnik is a typical karst, with water reaching the source from a submerged cave channel. At the mouth of the restaurant “Kamačnik” is located, which offers visitors a holiday with local food and drinks.
