A road book is a detailed guide used mainly in adventure trips, especially during 4x4 raids or expeditions. It is essentially a document that describes the route to be followed, step by step, with precise indications on roads, paths, points of interest, distances, directions to be taken and possibly information on weather conditions, accommodation or services available along the route. For 4x4 adventures, a road book is a vital resource because it guides participants through terrain that is sometimes difficult to navigate, off the beaten track. This allows participants to stay on track, plan stops and stages, and ensure that they safely explore areas that are often remote and little frequented. Live an adventure without the constraints of tedious upstream preparations and without too much risk of having to turn around if you had followed a track that ends nowhere. Once it's adventure, 10 times it's annoying and 100 times it spoils the pleasure of your vacation.
