The Tykakh is a left tributary of the Yana. It has its sources at the confluence of the Arga-Sala and Ilin-Sala —both having a length of — at the edge of the northwestern part of the Yana Plateau, near the southeastern end of the Kular Range of the Verkhoyansk system. The river flows first northeastwards, bending in a wide arch roughly in mid-course and then heading southeastwards within the mountain area. Towards the end it meanders heading in an eastern direction in its last stretch, where the river enters a swampy area with lakes. Finally it meets the left bank of the Yana from its mouth. The nearest inhabited place is Batagay, located upstream from its confluence with the Yana
