This paragliding site, with an elevation of 418 meters, is rarely used and restricted to members only. Top landing is normal here. For more details, you can watch this video: [YouTube Video](https://www.youtube.com/watch?v=ThKpV8DvtFc). Take-off: The site is accessible from Crumlin or Pontypool via the A472. At Hafodyryns, take the minor road leading to the back of the common and a track. Vehicular access via the track requires permission from the Trustees of the Llanover Estate. Note that the ground can become very boggy during wet months. Alternatively, you can access the site by a public footpath up the shoulder of the hill. Parking: If using the footpath, park at the Mountain Air Picnic Site. Take-off: Minimal carry if using the track, but a long carry if using the footpath. The take-off area is awkward, with tall ferns and ditches to watch out for. Landing: The top landing area (A) is tricky for hang gliders and requires careful planning due to the presence of a mast. Paragliders will find slope landing difficult because of the steepness and bracken cover. Both hang gliders and paragliders can land on the first shoulder (B). Hang gliders should avoid landing on the broken ground near the car park (C), and paragliders need to be precise when landing there. Hang gliders can land on the flat part of the common near the Lamb Inn (D). High-performance hang gliders can also land at the sports field, but this is a long glide and not recommended for intermediate gliders. Flying: During the initial height gain, be cautious of turbulence from the trees below ridge level, which can become severe in strong winds. Hazards: There is a clay pigeon shooting range behind the Mountain Air Inn on Sundays; look for the red flag. Other Rules: This is a sensitive site. Please respect the rights of other users of the common. Site Status: This site is exclusively for members of the SE Wales Hang Gliding and Paragliding Club and the Welsh Free Flight Federation, flown with the permission of the Trustees of the Llanover and Pontypool Estates.
