This Thursday and Friday, the soldiers of the Chamonix Brigade will go to the
Planpraz paragliding take-off area between 11 am and 2 pm in order to make the
paragliders aware of the prohibition by joint municipal decree of the town halls
of Chamonix and Saint -Gervais to land at the top of Mont Blanc. This device is
put in place because of the over-frequentation and the lack of equipment adapted
to the high mountain. The amateur public will be more targeted.
