Hello! I am traveling to Hannover, Germany, and wish to spend a day or two hiking/walking in the Alps/foothills of Alps while I am there in the beginning of June. I would ideally like to travel to a less crowded place. Wherever I go, I will be traveling there by train, and I'd like to be close to Freiburg (since I will be going to the Black Forest next!). Could you give me an idea of where I should go?
Thanks!
