Afon Tryweryn is a North Wales white water asset of immense value. The dam controlled releases of water ensure that it can be paddled throughout the year, although you will need to check with the National Whitewater Centre which is based on site for water level information (01678 520826).
While the Tryweryn retains a wild river feel the upper 2 km section of the river has been re-profiled to ensure optimum paddling conditions and provides some superb class III to IV rapids.
Below the centre a 6km section of class II to III white water give a great river journey experience down to Bala. Bala Mill Falls provide a sting in the tail at class IV just before the end but it can be portaged if necessary.
There are occasional events or competitions held at the centre – on these days recreational paddling is not available. The centre also provides regular white water rafting sessions. Paddling on the Top Site area (at the top of the river) is not open to the public if it has been booked out by a group.
The site has excellent facilities, including parking, hot showers and a café.
