Botswana or Zambia? Which country would you choose out of the two for Safari, and for adventure?
Any advice for or against each would be great.
Would very much prefer a non touristy experience, so if there is anywhere someone would recommend that would be great.
I never been on Safari in Zambia, but several times in Botswana. It a lot to choose from but Okavango Delta and Central Kalahari Game reserve are two highlights. But you also got other areas like Chobe and Savuti. Botswana is not a touristy place nor is Zambia. Botswana is pricey especially if you book something in advance. I had a terribly ecperience with a prepaid tour where everything went wrong. I suggest that you fly in to Maun which is the safari capitol of Botswana, but much less busy than Arusha. Get a hotel there and ask for advice, and arrange the safari from Maun. There are no lodges in Central Kalahari so you have to arrange a tented affair if you go there. In Okavango and other places there is a lot to choose from. It is pro/con whether to arrange something prepaid or doing it on site, but I wasted 20000 US on my last tour to Africa
As for Zambia, it's also quite expensive compared to Malawi/Tanzania. Distances between cities is huge too. The parks are almost inaccessable without transport, but if you take the train down to Livingstone (great journey!), you are right beside the victoria falls (which is overdeveloped for tourism, I believe), where you can do most things independently.
When I went to Zambia we were in rented Land Rovers from Malawi, and went to South Luangwa NP (amazing), down to the Zambezi and to Vic Falls and back to Lusaka and Malawi. The distances are huge, so renting vehicles might be a plus, although there are plenty of long distance busses. My advice is to go to Malawi, where everything is much closer together!!
