For an experience like no other, try bush camping in the reserve. Instead of living in a luxurious lodge or hotel, you will be camping in tents.
Live inside a tent, eat around the campfire, interact with other guests, watch elephants meandering around by the lake and have a peaceful, completely unique experience overall. This is what bush camping is all about. Any kind of stress that you may have will simply melt away after this. You can ask at your hotel for the most popular bush camping sites and then head over.
