La Drôme des Collines is a hilly area around Romans-sur-Isère with 22 mountain biking routes totalling 600 km which take in the whole area, including a grand circuit.  It offers a hugely diverse area of countryside and landscapes, with lots of different kinds of terrain, making it suitable for bikers of all abilities, offering everything from a gentle potter to a challenging ride. I've been mountain biking for more than 20 years. The kick I get out of the speed, the jumps and the turns is a great escape for me.
