Sixty-five volunteers are sleeping at the summit of Snaefell this weekend!
The sleepover’s been organised by Breakthrough Breast Cancer, and hopes to raise awareness and funds, as well as give the guests chance to remember their loved ones.
Half the money raised on Saturday will be going towards the creation of a dedicated breast unit at Noble’s Hospital.
But it’s not just the sleepover that’s taking place, and the organisers are looking for me people to get involved.
