In reply to Toerag:
I assume you're staying at KISC? If so the reception are great for recommending routes for walks, and you can borrow maps from them, when i get home i can tell you who makes the map i have.
Afraid i cant give you much on good routes to do, even having worked there for 2 months, but i know alot of groups do the walk across to 'our chalet' and back over two days. Or for a day walk, up to the Frundenhutte or Doldenhutte are very nice.
Very jealous you're going, after working doing their snow and ice activities last summer, i miss kandersteg so much
