Vehicles used to conduct safaris in Tanzania are custom made, four wheel drive Land Cruisers with pop up roofs. When in the park, the roof is open and there is no barrier between you and the animals. Do not be alarmed, the safaris are not dangerous and guides carry no guns. Though the animals are indeed wild, they are also accustomed to the presence of humans in vehicles. For their entire lives, they have seen vehicles regularly driving across the savannah and have grown to ignore them. The animals do not attack tourists, their non-reaction is what allows us to observe them freely in their natural habitat without disrupting their normal behavior. There are times when the animals will interact with visitors, for instance lions will sometimes lay underneath the car to get some shade. A cheetah might jump on the vehicle to get a better view of its surroundings (if this happens, stay calm). These can make for very special moments to remember forever. Caution: remember to stay in your vehicle expect for designated areas where it is allowed to exit as animals are not used to seeing a person outside the vehicle, as a result then humans can be a threat or a potential prey to them. If nature calls, let your guide know so he can take you to a restroom or find a safe, clear spot for you to get out.
