In reply to Tony the Blade:
I was there on Wednesday - first time since 2002 - and my heart ached at how much the glacier had receded.
The ladders can be daunting, but not difficult, and the second section is all set up with fixed carabiners. However, once you get to the bottom of the last ladder, there is a short sketchy bit of rock before landing on a very steep snowy section with loose rock and gravel.
As has been suggested, it may be best to go from the grotto, and on the way back, have a look at the ascent up to the ladders and decide then.
Regards,
Kris
