About the fishery

Alwen is an unstocked reservoir offering permit-controlled fly and coarse fishing through Welsh Water's Llyn Brenig operation. The operator also describes spinning and single-worm trout methods, with fly-only fishing north of the bridge. Access is through Alwen's own car park; the neighbouring Llyn Brenig visitor centre provides permit sales and support.

Fishing access and booking

Access

  • Type: permit_fishing
  • Permits: Llyn Brenig fishing shop; site also describes permit machines. Confirm exact Alwen ticket/machine availability.
  • Season ticket scope: Brenig/Aled Uchaf season product also valid for catch-and-release coarse fishing at Alwen and Aled Isaf.
  • Methods: Spinning, natural fly and single natural worm except north of bridge, where fly only.
  • Conflict: Operator summarises Alwen as fly/coarse catch-and-release, yet also describes spinning/worm trout fishing. Preserve both; confirm method/species restrictions on actual permit.
