An accurate list of the highest peaks in Africa can be found on Wikipedia here: Wiki List of Highest African Peaks
The prominence used for ranking is 500m. That means that if the saddle (low point) between the mountain and it’s parent mountain (next highest closest point/mountain) is smaller than 500m, it is only considered a secondary peak to the parent. If the altitude between the saddle of the mountain and the parent is more than 500m, it is considered it’s own mountain and given a rank. Rank numbers noted on our website are based on the same criteria as the Wiki page.
