The new series of Celebrity SAS: Who Dares Wins starring Katie Price is being filmed in Scotland - far from the harsh exotic locations previous contestants have endured.
Past series of the TV show were filmed in wild foreign locations, including Morocco's Atlas Mountains and the Andes in Chile.
But this series is being shot on the Isles of Skye and Raasay in Scotland, sources said.
Locals in the Inner Hebrides claim TV crews have been spotted on the islands filming the show which sees ex-special forces soldiers recreate the SAS's selection process.
It is thought this year's line up of celebrities, including reality star Price, 41, will stay in an old farmhouse on Raasay during filming.
The local claimed: "Obviously we don't want to cause a scene, but I've been told by a friend working with Channel 4 they're filming the show here.
"He'd said that he'd helped the crews go between Raasay and Skye, and said they'd be staying in a big old farm building.
"The celebrities are apparently due to arrive very soon."
Skye is home to the mountain range Cuillin, popular with mountaineers who enjoy scaling rocky heights with steep cliff edges.
And Raasay, famous as the birthplace of Gaelic poet Sorley MacLean, has a varied terrain, including high point flat-topped Dùn Caan (1,453 ft).
Celebrity SAS: Who Dares Wins pits contestants against harsh environments in life-or-death situations.
For two weeks, they undergo a notoriously difficult training course replicating Special Air Service Selection.
In April 2019, the fifth series featured Olympic gold medalist Victoria Pendleton and England rugby player Ben Foden.
Whereas Skye's population numbers around 10,000, only about 200 live on Raasay.
A spokesperson for Channel 4 said they could "neither confirm nor deny" claims that Celebrity SAS is being filmed in Scotland.
