On the northern side of the Grumeti River, there is a buffer zone/wildlife management authority where you reach after a 15-min drive. An armed ranger will be there for your protection while you will have the opportunity to explore new territory and perhaps follow the animals on foot! The walking safari takes approximately 1.5 hrs hours. What you will encounter is always a surprise. After your walk, you will be taken to the top of Robanda Hill for sundowners while enjoying the sunset over the Serengeti.
