The put-in on the Afon Tryweryn serves as the main access point for paddlers heading downstream through the National White Water Centre's managed course near Bala in north Wales.

A car park near the river allows paddlers to unload and make the short walk to the water's edge before beginning their run. The upper section of the river, below the Welsh Water stilling basin, is designated as the "Top Site" and is the primary paddling zone.

Flows are controlled by releases from Llyn Celyn Dam, typically between 9 and 12 cubic metres per second, producing consistent Grade III whitewater.

After completing their run, paddlers are returned to the put-in by shuttle bus, making this egress point an integral part of the centre's operations.
