About this flying site
A friendly site, with excellent XC potential. The main ridge has a large capacity and can support more than 50 gliders in good conditions. This reduces significantly as the wind goes off to the North or South, and the lift band narrows.
Take-off
West: When rigging or inflating paraglider please watch out hang gliders overshooting the top landing.
Landing
Top landing areas (A & B) are extensive and fairly flat. Watch out for rotor towards the top of the track on the right hand side.
Access and parking
26/5/2025 Note currently keys are only available for the North access gate. We are currently trying to obtain South keys, the locks look the same as the North lock but do not work.
Local weather notes
The usual hazards associated with a cliff edge in strong winds. There can be a sharp wind gradient in the top landing area, and strong sink in the lea of the hill. Don‘t land too far back.
Hazards and cautions
The usual hazards associated with a cliff edge in strong winds. There can be a sharp wind gradient in the top landing area, and strong sink in the lee of the hill. Do not land too far back.
Beware of ticks, especially if you are sat out the ground for significant peroids – sheep and horses graze on the common and these parasites have been found on the top.
