Golden Ball is a paragliding site located in the County of Wiltshire, UK. The site offers a grassy takeoff area with an elevation of approximately 260 meters (765 feet) AMSL. It is primarily used for cross-country (XC) flights, especially during the summer months. The site is sensitive and requires pilots to be full members of the Thames Valley Hang Gliding Club (TVHGC) to fly. Guest memberships are available for visiting pilots. The site is available year-round but may be closed due to farm activities, so it's essential to check before planning your flight. The wind direction is primarily from the southeast to south, and the site features a south-facing escarpment. Parking is available at the Golden Ball/Knap Hill public car park. Be cautious of car thieves in the area. Access to the takeoff area is on foot via designated footpaths from the car park. There are no designated top, slope, or bottom landing areas. Pilots should avoid landing beyond the fence east of the launch area. If an emergency landing is necessary beyond the fence, pilots must walk back to the takeoff position and not take off from beyond the fence. The site is close to Lyneham airspace, so pilots should carefully study their air maps and check NOTAMs for any reactivation of airspace or ATZ. Common XC routes include flying towards Marlborough and navigating around the airspace near Uffington Castle and the Vale of the White Horse.
