In the afternoon heat on the south-facing slope, very little shade. The last 3km are steep. Warning, no water at La Bâtie (cemetery gate locked), refill well before!

From Saint-Michel-les-Portes, it's about 7 km at an average gradient of 8%. The last few kilometers often reach double digits. A cruel climb if it's the last one of your day...

The Col de L'Arzelier isn't a very difficult pass, but it is long. Plenty of shade, which is great in the summer. Very little traffic.
