Climb to the viewpoint

...a great climbing section, which shortens the actual hiking trail a little, but also leads to the viewing rock. If you want to continue leisurely, stay on the GR221.

I missed the path to the side and took the small climbing section. Equivalent to T4 or a red/black route. The actual climbing section is small. I would recommend only by good weather and if you have a head for heights. If you're a competent hiker, nothing to worry about even with a backpack. :)

I cannot recommend this section of the route. Despite looking at the Komoot map and using my mobile phone to navigate, I kept missing the actual route by a few meters. That's probably why I didn't have to climb any of the routes. Sometimes you can't see the path properly and the ground is very slippery (in dry weather!). I didn't see any markings on the path and I didn't have a view.
I suspect most people prefer to take the detour because then you know exactly where you have to go.
