The Afon Ogwen is a seven-mile-long river flowing from the uplands of the Carneddau range in Snowdonia National Park down to the Menai Strait east of Bangor in Gwynedd, Wales. It is celebrated for its scenic beauty and provides diverse river conditions that appeal to anglers of all skill levels. As a classic spate river, its flows are heavily influenced by rainfall, which is often welcomed by local anglers as a rising water level can signal prime fishing conditions. The river supports a healthy population of migratory salmonids, with access available to most of the catchment.
