ISV South Africa

The only difficulties I had were with the taste of the water and apparent lack of meat hygiene! I never got sick and this has more to do with the area than the tour company. I could honestly say it was up there with, if not the best, month of my life. The host organisation is amazing and such a good resource for learning about the sad history of South Africa.
Some would say it's too expensive and I was inclined to think the same before I went, but it is worth it to have everything done, a perfect balance of fun and more meaningful work.
