About the National White Water Centre
The Afon Tryweryn below Llyn Celyn dam is one of the most consistently good white water rivers in the British Isles. The reservoir above provides controlled releases that maintain the river at appropriate levels for kayaking and rafting throughout the year — a significant advantage over rivers that depend on natural rainfall and are frequently either too low or dangerously high. The National White Water Centre has operated here since 1986, providing structured white water experiences for visitors of all abilities.
For most first-time visitors, white water rafting is the main activity. Groups of up to eight share a large inflatable raft, guided by an experienced instructor who explains safety procedures and controls the experience on the water. The Tryweryn provides several distinct sections of rapid — from the introductory bouncing water of the upper river to the more committed drops of the lower gorge. Guides manage the pace of the experience according to the group's comfort and ability.
The river has a historical and political significance beyond its sporting use. Llyn Celyn above was created by flooding the Welsh-speaking village of Capel Celyn in 1965, despite overwhelming opposition from the Welsh population and the Welsh representatives in Parliament. The episode was a catalyst for Welsh nationalism and a defining moment in modern Welsh identity. A memorial to the drowned village stands at the reservoir, and the Welsh Assembly later passed a formal apology for the flooding.

Frequently asked questions
The Afon Tryweryn is a mountain river below Llyn Celyn reservoir in the hills above Bala. It is one of Britain's finest whitewater rivers — the controlled releases from the dam at Llyn Celyn maintain consistent water levels and wave quality throughout the year, making it possible to raft or kayak in excellent conditions regardless of rainfall. The river has been a centre for British whitewater sport since the 1970s and hosted the 1981 World Slalom Championships. It is important to note that the 2012 London Olympics whitewater venue was Lee Valley in London, not Tryweryn.

Llyn Celyn is a reservoir completed in 1965 to supply Liverpool with drinking water. Its creation flooded the village of Capel Celyn and the homes of 48 families, despite significant opposition from the Welsh community and the Welsh nationalist movement. The flooding of Capel Celyn was a defining moment in 20th-century Welsh history and a significant factor in the growth of Welsh political nationalism. A memorial to the drowned community stands at the reservoir. The Welsh Assembly later passed a formal apology for the flooding.
The National White Water Centre operates throughout the year — one of its key advantages is the controlled release schedule from Llyn Celyn, which means consistent water conditions regardless of season or recent rainfall. Sessions are scheduled around release times, so checking the release calendar on the operator's website (ukraftingcentre.com) is essential before booking. Summer is the busiest period; autumn and spring can be excellent with fewer crowds.
