For those wanting some adventure, why not hike Mount Kenya? The superbly scenic, snow-capped peak of Mount Kenya is the second highest point in Africa at 5199m.
The main summit is called Batian and the second summit Nelion, both of which are technical climbs; however the third peak, named Lenana, at 4985m is more accessible and a very feasible goal for anyone with a moderate level of fitness. The hike is most commonly done over 5-7 days, depending on the route chosen.
