Golden Ball - paragliding only



Available all year round but this site may be closed due to farm activities so please check before you fly.  Use the Telegram Planning group to ask if there are any horse events that might restrict flying. 

Only take off in the designated area and NOT beyond the fence to the left of takeoff, if you see anyone doing so, please have a 'quiet word'.

Restricted to 'Pilot rated' Hill pilots:

Wind Direction / Details

South facing escarpment.

Restrictions (pilot or advanced rated pilots only)

In summer this site is only to be flown with the intention of going XC (cross country), in order to minimise impact on the hill and to comply with the landowner’s wishes. However the site can be flown all year round for soaring but typically there are fewer pilots so less of an issue.


This is a very sensitive site – The agreement can be revoked at any time.
There are lots of horses in this area, often ridden by inexpert riders.  As horses are easily spooked by low flying gliders. Never fly low over horses. 
It always helps to take time to stop and talk to other people using the tracks, preventing problems developing..

Please study your Air-map carefully; you are close to Lyneham airspace but from August 2011 the class D airspace and ATZ has been deactivated and the ATZ temporarily. Check NOTAMs for Lyneham to check if any aspect of the airspace or ATZ have been reactivated. Previously as a rough guide when the airspace was in operation a common route is to fly towards Marlborough; the hills just north of the town are the best bet. At its eastern end the CTR conveniently runs right along the A346 Marlborough to Swindon road, and its southern extremity meets the road about halfway between two obvious villages, Ogbourne St George and Badbury. Stay on the right hand side of this road as you go north and you are clear of airspace. After this, climbs can be found at the golf course north of Marlborough and east of the main road, Whitefields, Liddington or the continuation of Sugar north of the M4.

Uffington Castle has proved to mark a reliable thermal source. The crux is getting back up after the long glide from cloudbase over the chalk ridges near Uffington into the low ground in the Vale of the White Horse.  After that the Thames pretty much marks the Brize Norton airspace - stay south of the Thames, and the airspace becomes much easier after Oxford.

It is now possible to take more of a northerly route and fly past Avebury but note you have RAF Fariford and Brize Norton airspace to contend with.
