The Silyap Range rises in the central area of the Chersky Range, to the west of the upper course of the Indigirka. Although the range is one of the smallest of the system, it has some of the most massive mountains of the range. The Silyap Range stretches in a roughly west–east direction for about 100 kilometers (62 mi). The highest peak is 2,690 metres (8,830 ft) high Mount Chyon (Гора Чён), also known as "Gora Chen", an ultra-prominent peak.
The larger Borong Range, another subrange of the Chersky Mountains, rises to the northwest, and the Porozhny Range to the north. The northern end of the Tas-Kystabyt rises roughly 70 km to the south of the range.
