My very first flights on Jersey were here. There is an adequate launch site(Dusty Ground) towards the southern edge of the ridge with car parking nearby. The 240ft take off is not bad but the rough steep cliff faces can throw up some slight turbulence now and again.
Wind really needs to be about 250° - 280° to be direct on to the cliff face.
The launch site is within gliding distance of the only bottom landing area, a small carpark and gravel beach just west of the pinacle.
Top landing is available all the way round the site.
The Model Aero Club operate in this area so you might have to share the airspace at times.
