Crampons

I may have to buy crampons and ice axe for summer climbing in North Alps. Because I'm planning to walk Tsurugidani snow gorge near Mt. Tsurugi.
There is much permanent snow on there despite in August. As the surface is frozen, I'll drop down to the end of the gorge if I slip. So the items are needed.
As I'm beginner, walking there alone may be risky. I'll consider whether I'll go there or not for a while.
