Do you have any advice for potential travellers?
I was really glad to travel from south to north, going through the desert first, then to greener lands with all the wildlife to expect. The Falls where high on my list of expectations and as I said above, they exceeded them! Also it was quite cold at night in the south, so nice to move up to the warmth. It was really hot in some places, but always manageable, as most of the hot hours were spent in the bus anyway, with "open-windows-aircon".
I loved the camping, although the tents are not very big, and I could most definitely NOT stand up in them! I shared with a friend and we left our big bags in the truck to have more room. So it's a good idea to have a small extra-bag to carry what you need for one night. Once we got ourselves organized (easy by day 2), it was fine. I am not sure I would like to share with somebody I do not know, though, so I would suggest single supplement for people travelling on their own.
I took my walking boots, but hardly wore them, so waste of space. A keen photographer, I also took my tripod, but again hardly used it. A bean bag is perfect to rest your camera on, and there is plenty of sand around to fill it upon arrival! Make sure your sleeping bag is warm, it got really cold towards morning. And a good fleece is absolutely necessary! Clothes line is really useful, we used it all the time. Have a good mosquito repellent, we did and hardly had any bites. A powerful torch is also useful.
It is really useful to read the trip notes before you go, especially the part about money. Several people needed bank stops because they had not read them, and they are not always easy to find (or the ATM is empty...) Basically, we took SA Rands and US$ and were fine.
We do spend a lot of time in the bus, but the scenery we drive through is amazing, so I really did not mind. Also, we stopped frequently for fuel, supermarkets, drinks...and Magnum ice creams! Do not miss tasting the amazing Namibian varieties!
If you can afford the extra cost, you have to take the longer helicopter flight above the Falls that takes you inside the gorges!
The night safari in Etosha was also one of our highlights, and be sure to have a good flash on your camera. The animals do not mind, and at least you can get a few photos...!
