I took my family and we did a 7 day hike around Mt Blanc. started out in Chamonix and hiked around the south end of Mt Blanc, then to Italy, over into Switzerland and then back to Chamonix. An average day was around 18-25km with about 4000' of elevation gain.
We carried a day pack and food, and had our bags transported to the next hotel. This was a 10/10 adventure.
