Please note that this is not a travel site. It is about "backpacking" American style, which you probably call wilderness trekking. While many of us have done the sort of travel you contemplate, much of our travel was in the relatively distant past.

You will get far more help on a budget travel site such as Lonely Planet. I'd also suggest consulting a guidebook or two--they discuss mountains and lakes as well as cities, and there are guidebooks written specifically for those areas. The guidebooks I used most for European countries (of course that was 13-14 years ago) were Lonely Planet and Rough Guide. If you have library access, start there--even older editions are a good place to start.
