When little DS told me I was appalled. He was only 7and a half. This kind of hair raising activity I wouldnt consider until aged 11-13 yrs for my son. But no, my Ex to give Ds the holiday of a life time organised for him to go paragliding with the the instructor.....aaahh ! 
My Ds said he was a bit scared, but found it quite fun i think. Still think its not something most parents would let a child of this age do ,,, is it??
