In reply to Removed UserGRUMPY MONKEY:
I've done a fair few Hut to Hut Treks with extra mountains off-route, some with ropes, some without.
One of my favourites is the Stubai Rucksack Route (Horseshoe) in Austria, stopping at some huts for 2 nights to do mountains like the Wilde Freiger.
Excellent area, huts great with draught german beer.
For planning treks, Kev Reynolds 'Cicerone Book 'Trekking in the Alps' is well worth looking at, then get the appropriate Cicerone (or other) guide of the trek.
If you need more detail of the Stubai trek, email me. I've still got our plan showing the travel, huts and planned summits.
