Height: 535 meters This site is occasionally used for paragliding, offering opportunities for soaring and mini cross-country flights. Top landing is generally straightforward. There are multiple takeoff options available. Due to its sensitivity, it is recommended to contact the local club before flying. Region: Wales, UK Site Record: 43.0 km Videos: - [Video 1](https://www.youtube.com/watch?v=Tqp_lOubGvs) - [Video 2](https://www.youtube.com/watch?v=CxHL-KXwVgA) - [Video 3](https://www.youtube.com/watch?v=w5wRNH-xHfk) - [Video 4](https://www.youtube.com/watch?v=1xleqb05Mz8) - [Video 5](https://www.youtube.com/watch?v=-V6d45WIsNw) - [Video 6](https://vimeo.com/90400059) Local Club: [South Wales Soaring Club](http://www.swwsc.co.uk/index.php?topic=6.0) Wind Direction: NNE to ENE Takeoff Height Above Mean Sea Level: 1750 feet How to Get There: From M4 J45, drive up the Swansea valley on the A4067, passing the Dan Yr Ogof Showcaves and over the mountain pass. After passing the Cray Reservoir on your left, take the right turn signposted to Heol Senni. Continue for just over 2 km and turn right up a stony track just after the cattle grid. Park in a space clear of the track and walk up the hill. Hang glider pilots are advised to drive as far along the track as possible for an easier carry-up from the south end of the hill. Landowner and Site Fee: Managed by the Brecon Beacons National Park Authority. No fee is required. Rules: This is a sensitive site. Share vehicles whenever possible and do not disturb livestock. Peregrine falcons nest in the quarry and must be given space during the spring breeding season. Potential Hazards: In strong conditions, be cautious of the dry stone wall and barbed wire fence behind takeoff. Several gliders have been damaged here over the years. The bottom landing area below the hill slopes away deceptively. Low-flying military aircraft frequently use the area during the week; use the freephone service for updates. Takeoff and Landing: There is ample room for takeoff at either end of the quarry. The slope at the south end is gentler and easier to manage in strong conditions. Top landing in front of the wall is tricky for hang gliders, but landing behind the wall is acceptable, except behind the quarry where turbulence may occur. Hang glider pilots may bottom land on the flat area next to the track on the north side of the road. Site Comments: This is an excellent site for thermalling and cross-country flying over friendly terrain. The ridge is relatively short and can become crowded in light soaring conditions.
