Tourists have been warned to treat western Europe's highest mountain with respect - amid claims some are using it like a "theme park".
Mont Blanc is one of the world's deadliest peaks and around 50 people die in the area every year.
Some 200 people attempt to reach the peak of the 16,000ft mountain every day during the summer months.
But the local mayor in Saint Gervais on the French side of the mountain has told Sky News that overcrowding has become a problem.
It has also lead to situations where inexperienced people are putting their lives at risk by trying to do something they are not capable of, Jean-Marc Peillex said.
He said there are some who have no respect for the dangers and that some travel agents are to blame for not making people more aware of the risks - and the effort required to climb the mountain.
The matter has been debated in the past after a Polish climber rang the mountain rescue team to bring him back down the mountain because he did not want to walk back "on his own steam".
Such incidents demonstrate what officials want to avoid and guides want tourists to understand the risks and be prepared before they take on the challenging climb.
Mountain guide Yann Delevaux explained why Mont Blanc has a reputation for being one of the world's deadliest climbs.
He said: "Because it is very famous and it is the highest peak of Europe, many people are coming to Mont Blanc.
"The crowds make the statistics but if you take the number of people attempting Mont Blanc and the accidents, I don't think it is the deadliest."
His colleague Stian Hagen, who lives in Chamonix, said he has witnessed people walking down dangerous ridges without the right kit and appropriate clothing.
He said: "Every now and then you'd see people taking the lift up to the Aguille du Midi in shorts and running shoes, and walking down the Arete.
"Where you should have crampons and an ice axe to walk down.
"Some people just don't understand.
"That's the other end of stupidity but then you also have a lot of people who overestimate their own ability.
"They come here and think you can just do Mont Blanc and it's easy but they maybe don't know how to move in the mountains here and they are not capable of judging the glaciers and other dangers.
"Altitude is a danger too and suddenly you are not capable of taking care of yourself," he said.
Around 1,000 rescues are carried out every year by the PGHM - a specialist mountain rescue team.
Many incidents happen at the Grand Couloir - part of the most popular route to the summit.
That's because it is considered the most accessible, but it is far from safe.
The steep gorge is subject to almost constant rockfall in high temperatures.
In the last two decades, registers show that this section alone has resulted in at least 74 deaths and 180 injuries.
Last year, the route was suspended after it claimed the life of a 57-year-old man.
It remains a real area of concern for guides, especially for those who approach it without mountaineering experience, unguided and without an awareness of its deadly reputation.
Mr Hagen added that in the mountains, tourists should always look up.
He said: "Danger is things that are falling from above, and that can be rockfall but it can also be all serac falls.
"Seracs are big pieces of ice falling and you can get hit by it or enormous pieces of ice can fall off and create an avalanche.
"So you need to be aware of these overhanging hazards, on top of the underlying hazards of the crevasses," he said.
Guides hope that highlighting the dangers and educating people about climbing Mont Blanc will help reduce the number of incidents.
