The trail starts from Trail 5, before entering the Seven Stairs Canyon. The trail begins with a steep 20-meter ascent, veers to the left and continues with another 390-meter ascent (25.5% slope) to the upper part of the canyon. There is a variation of the route here, going down below the walls on the left for 90 meters until the intersection of Trails 5 and the variation of Trail 21. Trail markers continue to the left along the wooded ridge and in 350 meters, they take you down to Sipoaia valley (Trail 5).
