South African based operator, Sustain Safaris, offers some of the most focused mammal tours I have ever seen. I am a keen birder too, but mammals were my main focus for this trip. I was amazed that I had a personal tour with owner-operator, Michael Wright, who is an incredible birder and mammal expert. We stayed in many of the best value lodges in South Africa, and enjoyed excellent cuisines. Michael is also superb with logistics, and is extremely helpful in this regard. It was one the most incredible tours I have ever taken.
