The Brecon Beacons are just one hour north of Cardiff and are fast becoming a popular destination for hen parties with a streak of adventure in them. The mountains and rivers provide you with the perfect opportunity to try out some exciting activities such as Gorge Walking, Canadian Canoes and even White Water Rafting. The hen night may not be as wild as it would be in a big city, but there are plenty of cosy country pubs where you can enjoy good food and a few drinks.
