Tan-y-Mynydd – Welsh for “under the mountain” – is a long-established trout fishery set in the easily accessible North Wales countryside near Abergele, in the county of Conwy. It isn’t a Snowdonia venue – it sits closer to the North Wales coast, in Moelfre, a few minutes from Abergele – but it’s a genuinely well-regarded, immaculately kept fishery that’s built its reputation over more than five decades.
Over 50 Years in the Making
The fishery’s pools were first dug in 1971 and have matured naturally ever since, developing the rich aquatic life and natural food sources that produce strong, healthy trout. That maturity shows in the quality of the fishing – fish here test experienced anglers while remaining enjoyable and rewarding for beginners of all ages.
Five Pools, Two Approaches
Tan y Mynydd is built around five pools split into two distinct groups. Three dedicated fly-fishing-only pools each have their own character and technical challenges, and are fully stocked with a varied mix of rainbow, brown, blue, and tiger trout – giving genuine variety and progression through a season. Alongside these, two family-friendly pools allow multi-method fishing, including bait and fly, making them ideal for introducing newcomers, young anglers, and families to the sport without the fly-only restriction.
FlyRebel On Site
Based at the fishery is FlyRebel, a specialist offering carefully selected fly fishing tackle, premium fly tying materials, and its own merchandise, and an official stockist of leading brands chosen through genuine testing and time on the water – a proper tackle shop rather than a token counter.
Visiting
Full current ticket types, pricing, and rules are best confirmed directly on the Tan y Mynydd website before you travel. The fishery is at Moelfre, Abergele, Conwy, LL22 9RF.
If you’re bringing bait or spinning tackle for the family pools rather than fly gear, our guides on float fishing for trout and PowerBait for trout cover the bait-fishing side of stocked trout waters.
Nearby Fisheries
Tan y Mynydd sits within a reasonable drive of several other North Wales waters covered in this series, including Llyn Brenig and Graiglwyd Springs, making a multi-day North Wales trout fishing trip genuinely practical.
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.
