Nant y Moel, UK Elevation: 491 meters This site is regularly used and offers good cross-country (XC) potential. It is a private site, accessible only to members of the South East Wales Hang Gliding and Paragliding Club (SEW) and the Welsh Free Flight Federation. Top landing is generally straightforward. Region: Nant y Moel, UK Site Record: 123.2 km Wind Direction: SSW - WSW (200° - 245°) Best Direction: SW (225°) Minimum Rating: - Hang Gliding: Pilot - Paragliding: CP Access: From the M4 at Bridgend or from the Rhondda on the A4061. Alternatively, from Maesteg and Port Talbot on the A4017. Vehicular access to take-off is via a rough track, with permission from the landowners. Contact Mr. John Pugh at 01656 840436 before traveling to arrange gate access. Parking: Park sensibly by the side of the track adjacent to take-off. Do not obstruct the track or drive across the hill. If accessing by foot, use the designated car park and avoid obstructing the main road or gate area. Take-off: A long carry up can be avoided by using the track. Be cautious of rotor behind the cliffs; carry further over and take off well clear. Landing: The best top landing area is behind take-off, though it can be turbulent. The scree area below the cliffs is unsuitable for paraglider slope landings. The main bottom landing field is the Aberfields Extension at Pricetown, a long glide away. Avoid landing in the main sports field. Pilots can also land in the large field directly in front of take-off, which is bordered by trees and a wire boundary fence. The ground is rough, and it is a long carry out to the road or back to take-off. Do not land in the four fields adjacent to the road, as they are often used for grazing horses. Paragliders may also land at the base of the hill on open ground to the left of take-off. Flying: This is a fairly friendly site located in the scenic Rhondda, which has its own microclimate. Nant y Moel is often flyable when coastal sites are blown out. Hazards: Severe rotor behind cliffs.
