It is possible to visit the Park in a convertible car or jeep although this alternative does not offer as much protection (jeep, Tyrex, etc). Animals will be able to enter their heads in the vehicle and this reduces your security.
There are always risks involved in circulating amongst wild animals. The safety instructions that are given to you upon your arrival must be followed at all times reducing the risk of accidents with an animal. Not feeding the animals should keep them at a safe distance from your vehicle. Be safe you are driving at your own risk.
No, it is not possible to circulate in the park by motorcycle. However, there is an alternative: to rent a caged-in golf cart at the admission to visit the park. The n umber of carts is limited: first come, first serve, no reservation.
