Walk from Montreux to Jaman
If you’ re looking for an uphill walk that is more physical than from Nyon to La Dôle and Leukerbad to Lammenhütte then the walk from Montreux to Jaman will meet your requirements.
I did this hike with a group of people from Berne, Chateau D’Oex, and Geneva. It’s meant to take three and a half to four hours but we did it in a little over 3hrs, despite snow conditions.
