The area is rich with beautiful trails, try to find out what is suitable for you : Bosson Glacier, Planpraz to Chalet de la Flegere, Plan de l'Aiguille to Montenvers,Le Brévent,Le Lac Blanc. Some of the trails you need to take a lift , some maybe a gondola look them up.
The weather is crazy there check it out before you leave, and maybe this will help.
