I went on a 3 day/2 night private safari in Ruaha National Park with Bateleur Safaris.  The company was super-professional and gave wonderful service from beginning to end, communicating quickly, and always doing everything they possibly could to make my experience the best it could be. My guide was Rajipa David, the company owner.  Rajipa is incredibly knowlegeable, not just about the animals, but also plants, insects and birds; and he's very entertaining and fun to be with.  We saw an astounding number of animals - including lions. The driver, Stanley, was also wonderful, navigating the bumpy roads smoothly and gently.  It was the trip of a lifetime and I would highly recommend Bateleur Safari Tours to anyone!
