In the 1990s, I was a foreign correspondent and backpacked solo across Africa for a year. It wasn't the easiest of journeys but to me, it was the most challenging - and most rewarding - trip of my life. I kept records but the internet wasn't quite a thing yet, so I didn't 'blog' about it (although I did send an email newsletter, probably one of the first travel newsletters ever).
Back then, a woman traveling on her own across Africa was relatively rare - it still is. Africa isn't every woman's first travel choice because there is little tourism infrastructure and you have to do a lot of figuring out own your own.
But if you make the effort, you'll be surrounded by glorious wildlife, hypnotic scenery, wonderful music and a sense of humor you won't find anywhere else.
