Do you know of Mt. Kilimanjaro? It's a mountain in Africa, I desperately want to hike it one day.
Oh I do like hiking myself ! I understand it's the highest mountain in Africa. 
It is! It's also not a massively strenuous hike, unlike some of the more challenging mountains like Everest. Thus, you still need train but not nearly for as long. Where's your favorite spot to hike?
I've just hiked locally and in California. I've read that Mount Kilimanjaro has many scientific studies done on i because of shrinking glaciers and disappearing ice fields.
