There are plenty of lists online of the highest mountains in Africa - some include small subsidiary summits that are barely summits, such as Point Lenana on Mount Kenya, while some have glaring omissions such as Mawenzi on the slopes of Kilimanjaro.
Incidentally the Tanzanian government doesn’t recognise Mawenzi as a mountain, despite its 849m prominence (which is more prominence than Lhlotse, the 4th highest mountain on earth), as it would mean that Kilimanjaro is not free standing - rendering its claim as the highest free standing mountain as untrue. Any consistent and reasonable definition of a free standing mountain will either render Kili as not free-standing, or not the highest. But I digress.
Process of identification: using satellite survey data for the continent, I have run the numbers on every summit on the continent with at least 200m prominence and 500m elevation. All summits above 2800m were further subjected to a requirement of at least 7% prominence relative to height, 7% being the standard used in the Himalaya and the Andes. As a reasonableness test, I then compared my top 10 to a number of online top 10 lists and did research on any peaks they listed that weren’t on my list. Satellite data isn’t always perfect, and definitions are subjective - so naturally not everyone will agree with my list.
Here’s my list of the 10 highest mountains in Africa:
- Kilimanjaro (Tanzania) 5895m, prom: 5883m
- Mount Kenya (Kenya) 5199m, prom: 1899m
- Mawenzi (Tanzania) 5149m, prom: 850m
- Mount Stanley (Rwenzori - DRC/Uganda) 5109m, prom: 3951m
- Mount Speke (Rwenzori - Uganda) 4890m, prom: 730m
- Mount Gessi (Rwenzori - Uganda) 4806m, prom: 615m
- Mount Baker (Rwenzori - Uganda) 4790m, prom: 474m
- Mount Emin (Rwenzori - DRC) 4776m, prom: 498m
- Ras Dashen (Simien - Ethiopia) 4620m, prom: 3997m
- Meru (Tanzania) 4566m, prom: 3170m
Incidentally I have run this for the top 50, but I am struggling to find names for 26 of them, which is why I have limited the above to the top 10.
