French authorities say a heavy police presence is planned for the week-long operation, scheduled to start on Monday.
Over 6,000 asylum seekers, from mainly Africa and the Middle East, have been living in the temporary camp.
Aid groups, however, say that number could be as high as 10,000.
Among them are around 1,300 unaccompanied children.
Charity workers have been explaining how French authorities will begin dismantling the camp to migrants.
The operation, over the course of a week, will be a tense one and many volunteers have expressed worry over a lack of information.
Migrants will be told to report, voluntarily, to a reception area.
There, they'll be asked for their name, age and nationality before being taken by bus to one of 280 reception centres set up across France, where they'll be given the chance to apply for asylum.
But many are still desperate to get to the United Kingdom.
They were hoping to start a new life in Britain, just 80 kilometres away on the other side of the Channel, by trying to smuggle themselves aboard trucks.
This man from Iraq has vowed not to leave the camp.
"I will sleep on the street if they remove the camp."
(Reporter:) "You'll sleep on the street?"
"Yeah."
(Reporter:) "In Calais?"
"Yeah. Here. I will not move one inch from here."
(Reporter:) "Why?"
"Because I have one hope, to get to the UK, and I don't have any other option."
French Interior spokesman, Pierre-Henry Brandet, says authorities stand firm.
"Preventive measures have been taken. Police and the gendarmerie have undertaken very tight surveillance operations, which is why a high number of security forces have been mobilised, not to facilitate the dismantlement, but to secure the area."
Last month French President Francois Hollande vowed to tear down the makeshift camp, citing not only squalid, unsanitary conditions, but also fears for law and order.
Meanwhile the plight of those most at risk, the camp's 1,300 unaccompanied minors, has been in the spotlight.
This weekend the first group of 80 vulnerable children without family ties to the UK arrived in London, to be resettled in foster homes.
Their identities were concealed after earlier arrivals, who were being reunited with family, sparked accusations they were too old.
Calais authority spokeswoman Fabienne Buccio says they're the latest wave of children to cross the Channel under a recent agreement between Britain and France.
"It's true that for the past few weeks we have intensified our work (with the UK authorities). I can already give you a figure, this week, as we speak, practically 200 children were able to go to the UK. Before it was much more complicated."
But speaking from the Calais camp, Baroness Shaista Ahmad Sheehan, a peer in the British House of Lords, accuses the British government of not doing enough.
"They have been very very complacent. What they have done last week is very welcome but if you don't mind me saying, I think it's too little and it's too late."
