Parc Bryn Bach is set in 340 acres of idyllic grass and woodland and our event is being held on a stunning 36-acre lake at the heart of the venue. The lake is in a fantastic location that welcomes family and friends to support the swimmers as they swim the lake.
Parc Bryn Bach is located just off the A465 Heads of the Valleys Road.
Visitors should follow signs for Tredegar and once you’re off the A465 just follow the brown tourism signs for Parc Bryn Bach.
