English: Bala Mill Falls The Lower Tryweryn runs from the whitewater centre down to the main road bridge in Bala village and is mostly grade 2 to 3. Since the river is dam-released, it is often possible when other rivers have no water, and you can phone in advance to check the release level (if any). Under the Welsh Canoeing Association's new access policy, there is no longer any charge for using the river. The one hard rapid, Bala Mill Falls, usually given grade 4, is towards the end of the run, and is often portaged river right where a permissive path runs next to the leat. This photo was taken from the end of the portage (when I was new enough to kayaking to choose not to run the falls). The usual approach is to break out river left above the falls, from where you can get an idea of the line, but breaking in and choosing the right spot is the most difficult part. The paddler shown has got the right line and is just blasting through the bottom stopper. Offline, the first stopper or a hidden rock may slow the boat down, then this bottom stopper has a tendency to backloop boats, especially shorter playboats. Below the aerated pool, there is a relatively calm pool in which to collect swimmers and equipment.
