I have a work trip to Nairobi in December for 5 days, and I was thinking of tacking on an additional 3-5 days to explore. I haven't spent much time in Africa (just Egypt and Morocco), and would be potentially interested in seeing some animals (Masai Mara?), or something else naturally beautiful. I'd like to get out of Nairobi as I will have just spent the week there. What would there be time for in 3-5 days? Also, I'm a 28 year old woman, and will be traveling alone.
