It’s an uninhabitable granite island situated more than 200 miles off Scotland’s west coast.
To date just 110 people have successfully landed on Rockall in the past two centuries.
Only five have stayed for more than one night.
Now, four adventurers, including Cam Cameron from Moray, will camp on the lone rock, which pokes out of the North Atlantic.
Their week-long challenge will involve enduring extreme weather conditions and sleeping on the rock’s one-metre-long ridge.
Their aim is survival, as well as raising £1m for charity.
Mr Cameron told STV News: “It’s an extreme challenge, it’s extremely difficult.
“Only 4000 people have been to the summit of Everest, just five people have actually lived on Rockall.
“It’s 17.5m high to the sea level and waves can get to twice the height.
“We have planned it so we hopefully will have relatively calm conditions.”
It will take the team between 24 and 36 hours to reach the rocky outcrop by boat, leaving from Arisaig in the Highlands.
They’ll then transfer to a dingy before jumping onto Rockall with all their gear.
As well as portable stoves, the team will also take a purpose-built aluminium pod for all four men to sleep in.
Jake Watson, who helped to create the shelter, said: “If you can imagine a standard double bed in your house with a roof on – that’s pretty much the size of what they’ll be sleeping in, so it’s not very big at all.
“But it is perfect for the size of the rock and to give them a comfortable night’s sleep.”
More have been to the moon than have lived on Rockall.
But the men behind the expedition say it’s a risk worth taking to raise money for the hard-working charities they support.
