The first annual Illini 4×4 Safari event was held in May of 2002, following the final year of the Jeep Jamboree. It has been held every May since. It is traditionally very wet at the Safari event which makes the trails even more challenging and also increases the chance of trail damage. The available trails may be altered due to weather.
Participation is limited to 150 vehicles. Entry fee is $135 per vehicle (including driver) and $75 for each passenger over 10. This includes 4 meals meals (2 breakfast, 2 supper for each person), dash plaque, raffle ticket, and 2 days of trails.
