More ways to explore the area's outdoor wonders
The river takes charge before you do: cold mountain water funnels from a dam release, pushing a nine-cubic-metre-per-second surge through a short, concentrated run of churning drops and wave trains. You start at the riverside centre on the banks of the Tryweryn, suit up in a 4-season wetsuit and boots, and after a brief safety talk a shuttle carries the group to the head of the course.

History
The Tryweryn valley was transformed by the construction of Llyn Celyn in the 1960s; controlled releases from that reservoir now make the river reliably runnable.
Conservation
River releases are managed to balance recreation and ecology; visitors are asked to take litter home and follow guide instructions to minimise bank and habitat disturbance.
