Following weeks of heavy rain, the camp, known as the Jungle, has turned into a muddy bog with charities warning conditions have reached crisis point.
An increasing number of migrants are now attempting to stowaway in lorries and sneak into the Eurotunnel, forcing security at the tunnel to be tightened.
It has been reported that some 800 migrants threw stones at passing trucks in a bid to get them to slow down in order for them to try and clamber into the back.
It is thought that several vehicles were left with broken windscreens and had their cargo holds forcibly opened.
