Mount Gessi is among the six mountains that make up the Rwenzori range. Like Mount Emin, it is positioned north of the triangle shaped by Mounts Stanley, Baker and Speke. Mount Gessi is at an altitude of 15,018 feet or 4,578 metres and ranks the 5th tallest mountain in Uganda.
Mount Gessi and Emin are on either side of a long slim gorge heading north-southwards. The twin peaks of Gessi are Iolanda (15,470 feet) plus Bottego (15,418 feet). Mount Gessi is elevated to rocky north-south edge with the upper peak being at the south end. The mountain is characterized with huts and decent tracks from both the DR Congo and Ugandan side. From Mutsori in Congo, local tribesmen are present as to work as porters and guides. There are numerous shanties preserved all through the Rwenzori.
