I've stayed in the hut repeatedly, and been caught repeatedly. The worst that has ever happened was a polite talking too, and agreeing to pay for a nights camping (but then we stayed the next night at Catani) so nothing really. On other occasions I have seen the ranger around sun down, explained my plans, they were non plussed.
Mike is correct, you can see the route shortly after you pass Mushroom rock, from there on, the main thing you should have to worry about, navigation wise, is that you dont start up the bollocks looking variant start to the right. |
