The coolness in these gorges is much appreciated when it's close to a heatwave on the plains! And the wild atmosphere of the small road through these gorges (before reaching a busy road for a beautiful descent) is good (a little "kick in the ass" to get out!).

The climb to the charming Som from the Col de Porte is always a treat. There are some very steep sections, but the view at the top is worth it. Be careful on the descent: uneven road, tight bends, cars.
