This site offers a modest altitude range of 250-400 meters, with a takeoff height of 400 meters and a landing height of 140 meters, giving you a top-to-bottom distance of 260 meters. The best wind direction for this location is South-Southwest (SSW). Please be aware that during lambing season (March, April, and May), flying may be restricted. Always check for notices at the access point or contact the local club for the latest information: [Snowdonia Sky Sports Club](https://www.snowdoniaskysports.co.uk/cms/node/13). This site is primarily for gliding down and does not offer much for ridge flying enthusiasts. It is important to avoid landing in the fields north of Llyn Gwynant campsite and below the road unless you are at the Llyn Gwynant campsite itself. Challenges include the lack of a designated bottom landing area, requiring strong conditions for either getting away or top landing. Additionally, the site can become turbulent if the wind is slightly off from the southwest or behind the ribs south of the takeoff area.
