this one looks great but is it reachable without equipment looks really snowy
So if i am correct the turtmann route is easy F (facile) and the topali route has a via ferrata and is just a little bit harder PD- (peu difficile -)
Last year I went up the Topali side and descended to the Turtmann hut on 20 July. It was a fine day, with fantastic scenery.
Calling the ladder on the Topali side a Via Ferrata is rather generous. Sure, there is a bit of steel and it's very exposed, but it's also quite short. Falling is not an option, but there is plenty to hold on to. Perhaps it's already classified, I don't know, but if I would have to give it a Via Ferrata rating, it would be an A. In addition, I wouldn't rate the Topali route PD- either but F. If it makes you feel more comfortable, you can bring Via Ferrata gear, but judging by the way you've described yourself, you can do it without. Apart from the ladder, the route from the Turtmann side is never steep; in fact, the rest of the Topali route is just a hike. At the bottom of the ladder is a pretty harmless remnant of a glacier. The warden at the Topali hut assured me I didn't need any gear to walk across it, and so I did. At the time there was a little bit of snow on it.
Whether there is snow higher up depends primarily on the time of year. When I was there, it was almost gone. Mostly the trail was bare, but I did encounter a couple of small and harmless snow fields. The Turtmann side is not very steep, so even with more snow, as long as it's not icy or the snow is really hard, you can stop a fall even without an axe. Again, no special gear needed.
