The majesty and size of the French Alpine climbs makes this area a must for any keen cyclist. With a great infrastructure of facilities geared to skiing in the winter and cycling/walking in the summer, travel in the Alps is hassle free. The characteristic hairpin climbs will not disappoint you, and the iconic views of high and impenetrable mountains above you offer a superb backdrop to your days on the bike. Infamous greats include the Col d’Iseran, Galibier, Telegraphie and Izoard. Best visited from July to September, the cols can still be impassable in June if it has been a heavy winter.
