If you like surprises, then a 4x4 GPS Challenge might be your kind of fun. But we can't realy guarantee whether you will be pleasantly surprised or not. To get started on with this activity, you can group yourself into teams of four and go hunting for a certain number of 4x4 vehicles. But girls, this is not as easy as easy it sounds. You will have to navigate through rough terrains and risky routes. And there will be ample amount of surprises and misleading things thrown in your way. More than an adventure activity, this is more like a team thing where you can work towards tracking down your vehicle. You can take the help of  a GPS device and refer to  a route map to make things easier for you. But if nothing helps, there is a remote possibility of you being lost as well. But if you are cool headed, 4x4 GPS Challenge is a great activity you can undertake.
