wet hike

We checked out a (im)possible school trip for my class. Nice for us (well I think it is, but we didn't see much since it was foggy and even rainy, only here, nowhere else in the country today!!). The Hike is probably impossible with pupils who are partially not used to mountain paths at all, because there's a passage through a steep mountainside and another one with a slippery path when wet. And it's autumn, so it's probably wet. We need to find an alternative.
