Few minutes ago on a Polish TV news channel there was a segment about Mont Blanc and how many unprepared people try to climb it each year. At the end of the segment the presenter stated that from now on only French guides will be able to guide people up the mountain and that a permit is now required to climb.
I did some research on the Internet, but I couldn't find any info on the permits that are now required, I could only find old forum posts with this question and answers stating that no permit is required, I didn't find any recent posts so I would like to know what the situation with permits is like at the moment.
