Height: 310 meters, Height Difference: 210 meters This site is rarely used. It offers soaring opportunities and some potential for cross-country flights. It's a nice spot for thermal days. The top landing area is fairly extensive and quite flat, but the lift band is narrow, making it challenging to gain enough altitude for top landing if you drop below the hill's summit. There is no defined bottom landing for the NW side, so if you cannot top or side land, you may need to fly back towards the NW corner of the hill and land by the side of the road or in the emergency bottom landing field (B). Region: Caerphilly, UK. Site record: 56.8 km. [Watch a video of the site](https://www.youtube.com/watch?v=6heLfL3TK3M) This is an open site. View the [Site Guide](https://paraglidersite.wordpress.com/2013/07/06/mynydd-meio-site-guide/) and [Site Map](https://www.flysouthwales.co.uk/site-guides/mynydd-meio/). Minimum rating for both hang gliding and paragliding is CP. The wind direction is SSW to WSW (210° - 245°), with the best direction being SW (225°). This site is accessible to all suitably insured hang glider and paraglider pilots. The South East Wales Hang Gliding and Paragliding Club's website is currently switched off. Contact them via [WebCollect](https://webcollect.org.uk/sewhgpgc). For more information, email info@paraglidingspots.com. Road access is via minor roads from the A470. Parking is available alongside the road on the verge. Access to take-off is by foot only, involving a short, sharp carry up the hill. The rigging area is large and the take-off is friendly. The top landing area is extensive and quite flat. Paragliders can bottom land on the open hill alongside the road (A), but there isn’t enough room to safely land a hang glider there. The emergency bottom landing field for hang gliders (B) is at the bottom of the hill to the right of take-off. This field is small and the landing approach is difficult. Do not fly a hang glider unless you are sure it’s soarable or you possess the necessary skills to land in the emergency landing field. Avoid landing in any other enclosed fields or climbing walls or fences. This site can be a good choice if Merthyr is blown out. It’s fairly friendly away from the power lines, but the short ridge length and narrow lift band limit the capacity of this site on non-thermic days. Beware of power lines and the TV mast. Keep a sharp lookout for model aircraft. The A470 valley in front of take-off is full of power lines and pylons, so pilots should not attempt to fly to the valley bottom. This site is frequently used by model aircraft pilots. Please respect their right to fly as well as your own. This is an open site and may be flown by suitably insured visiting hang glider and paraglider pilots.
