At least 10K individuals are forced to escape campsites and houses once a replacement hearth bust out on the French region.
Wildfires have already consumed swathes of forest in tourist-packed southeastern France in recent days, as well as on the island of Corsica.
The new blaze, within the middle of the vacation season, is raging close to Bormes-les-Mimosas, southwest of the popular resort Saint-Tropez on the Mediterranean coast.
The fire broke out just before 11pm on Tuesday and burned 800 hectares of forest by Wednesday morning, with 540 firefighters sent to tackle the blaze.
Around 3,000 campers were among those evacuated from La Londe, La Lavandou and Borme-les-Mimosas.
A fire service official said: “The evacuations, at least 10,000, followed the progression of the fire. It’s an area that doubles or triples its population in summer.”

Tourists in 1,000 inhabitancy plots were forced to escape, in step with Lisa Minot, The Sun’s travel editor, who was at the scene.
She told Sky News the evacuation began around 2am on Wednesday, with holidaymakers told to head to the campsite’s private beach.
“We could see the flames just behind the campsite and we were told to evacuate right down on to the beach,” she said.
“The camp I’m at, Camp du Domaine, has its own private beach and then it goes all the way up into the hills.
“Everybody was told to evacuate to the beach and they’re still there and they have not allowed us to go back to our caravan.
“It’s utter chaos, there are no provisions or anything else… there’s no one telling us what to do.”
Firefighting planes were heading to and from the sea to collect water before dumping it on the flames, while the campsite’s sprinkler system was being used in an attempt to stop the blaze jumping across from the hills.
But Ms Minot revealed the efforts are being “hampered by incredibly high winds”.
Her mother Carol Bielfield was also at the site and said holidaymakers were trying to stay composed.
“It was keep calm and carry on, make some tea, serve some biscuits and hope that you get some information,” she said.
“But we’ve had no information at all. Everyone gave up, started leaving the beach and then the sirens went off and we were told to go back to the beach, but there’s not been any information.”
Local tourist site Fort de Bregancon, the former official retreat of French presidents, has been shut due to the fire.
