Veliki Šumik is 24 meters high. The water slides down the waterfall at a 42-degree incline. Despite the steepness, the waterfall is very picturesque due to its width and abundant flow. 400 meters below Veliki Šumik, at the Lobnica, is Mali Šumik. The water falls first in three cascades, totaling 9 meters, and then over a tonalite ledge nearly vertically for an additional 9 meters. On the rocks near the larger waterfall, there is a solitary habitat of rusty alpenrose (Rhododendron ferrugineum) and, slightly below, the fragile saxifrage (Saxifraga paradoxa).

Veliki Šumik is the largest Pohorje waterfall and the largest Slovenian waterfall on a non-limestone base, plunging 24 meters into a pool below a smooth overhanging wall, where at the end of June, rusty alpenrose blooms in an inaccessible crevice. On the rocks around the waterfall, which are damp from the splashing spray of the wild water, plants that love moist, cool, and shady conditions have settled, such as the unusual rock saxifrage, the broad-leaved golden saxifrage, various lichens, and mosses, which typically only thrive on limestone elsewhere. Here, however, they have settled because the water seeping and meandering through crevices between the rocks also washes and dissolves even the thinnest layers of limestone, depositing it where it evaporates, thus creating conditions for the settlement of basiphilous plants.
