Mid Wales’ trout fishing centres on the Cambrian Mountains and the upper reaches of the River Severn, and it offers some of the most genuinely wild, dramatic trout fishing anywhere in the UK – from the reservoir-scale stocked fishing at Llyn Clywedog to true wilderness fly fishing across the Elan Valley’s four reservoirs and the loch-style boat tradition at Lake Vyrnwy.
Fisheries Covered in This Guide
- Llyn Clywedog Trout Fishing Guide: Mid Wales’ Hard-Fighting Reservoir
- Elan Valley Trout Fishing Guide: Wild Brown Trout in the Cambrian Mountains
- Lake Vyrnwy Trout Fishing Guide: Loch-Style Boat Fishing on the Powys Border
Each guide below covers what the fishery actually offers, current access and permit information via the fishery’s own website, and how it connects to nearby waters if you’re planning a longer trip. See our brown trout and rainbow trout species guides for background on what you’re likely to catch, and our spinning for trout, float fishing for trout, and trout rod guides for tackle and technique that applies across all of these waters.

Sarah Marsh came to fly fishing through her father, who kept a rod on a small syndicate water in Devon. She spent her teens fishing stocked reservoirs and gradually worked her way toward wild fish on moving water – first on rain-fed freestone rivers in Wales, then on the Hampshire chalk streams she now considers home water.
She holds a level 2 APGAI fly casting qualification and guides informally on the River Test and, from June to September, on a private beat on the River Tay for Atlantic salmon. Her personal best brown trout came from the Itchen at 4lb 1oz; she’d sooner not talk about the salmon that came off at the net last August.
At The River Bend, Sarah writes the game fish species guides, fly fishing technique articles, and the legal content covering trout and salmon regulations.
