A superb climb on smooth asphalt, even if it's not the most popular climb. Therefore, traffic is very light, which I personally find more important. Up to Chalet Reynard, you're surrounded by trees. Views are rare. Overall, the climb is very pleasant and suitable for those who want to take it easy.

It is on the square in front of the old summit observatory that most of the cyclists who climb Mont Ventoux meet because the sign “summit of Mont Ventoux 1,912 meters” is there and all the climbers of the whole world wants to take the famous photo. There is sometimes a queue. On this square are the Belvedere of Provence which offers views of the Albion plateau to the Mediterranean and the Belvedere of the Alps which opens onto the northern part. On a clear day, you can clearly see the department of Drôme, the Pre-Alps and the Alps. By climbing slightly to the base of the antenna, you will be able to read below written on the ground, in large figures, the new official measurement of the Giant of Provence by the IGN: 1,910 meters.
