I have been riding a mountain bike for over 20 years and to try mountain biking in its cradle has always been one of my dreams. We visited USA during autumn, when Rocky Mountains in Colorado had not yet been covered by snow and the temperatures in desert areas of Utah had already been pleasant. We found amazing trails which lead through deep forests, over mountain ridges or red rocks. Trails which test your technical skills, fitness and even fear, but which make you smile in the end.
