My husband and I went on this trek when they first started them. There is some walking but most of it is in the jeep or standing in the "Boma" in the middle of the savanna. The only animals you get really close to are the hippos. Yes you do walk over a shaky bridge with crocodiles underneath, they are not that close to you. They ride through the same savanna as the Kilimanjaro safari, you might get a little closer to the animals and it does last longer. There are binoculars available in the jeep and in the Boma. We did have fun but I really did not think it was worth the money. If you go to trip adviser it does get 4.5 star but if you read comments even from the people that give it 4 stars quite a few say they were disappointed with the ride through the savanna and the animal "interaction".
