If you read the tips for this climb here, it is uncertain whether the people who gave the tips actually went through it.
If you are used to walking in the Alps with everything that goes with it, you will find this mountain a bit "strange".
The Devil's Ladder is actually a water-bearing stream bed that is quite steep, and only "sure-footedness" does not adequately describe this climb (you can't imagine the descent). In the Alps, no one would attempt a climb like this without a helmet, that's where it starts, because everything is slippery and loose. When you have managed the Devil's Ladder, you are halfway up and still working your way through raised moor and rocky scree. There are no paths in the Alpine sense. This also means that there are no, really NO, markings of any kind. Instead, fog and low-hanging clouds quickly set in, making it impossible to find your way. You shouldn't do it without a Komoot tour on your phone (or similar), because there is no way to orient yourself and the paths are hardly recognizable as such, especially in the fog.
The summit cross at the top is cool, but you should be prepared for challenges on the way down.
At the parking lot below you should have 2 euros for the fee. The pub down there is nice. There is nothing on the mountain (just for the sake of completeness).
So if you're more into hiking than climbing, you should be prepared for a 5-6 hour challenge. Without high shoes you can hardly get up and then you have to carry half the raised moor down with you, because you have to climb into passages there. Being sure-footed and not afraid of heights is something to be taken seriously and literally. I wouldn't do it without a helmet again.
