Celebrating F i f t y Years

Brought to you by Welsh Water

Welcome to Llyn Brenig


Llyn Brenig, near Denbigh in North Wales, is a hub for outdoor activities, wildlife and wellbeing located between the popular tourism centres of Snowdonia and Conwy. Things to do include watersports like paddleboarding, kayaking (hire or self-launch), recreational boats and open-water swimming in summer plus bike hire, sauna and cold water dipping all year round.

For anglers, there’s world-class fishing in the clear cold waters of Llyn Brenig, Llyn Alwen and Llyn Aled.

Our walking and cycling trails offer opportunities to immerse yourself in nature across 2500 acres of forest, moorland and lakes amid stunning upland scenery.

You’ll get a warm welcome in our visitor centre with café, gift shop, fishing shop and osprey exhibition.

And of course, Llyn Brenig is a summer breeding home of ospreys with numerous opportunities to catch sight of these magnificent birds from a manned dedicated lookout, photography hide or even at home via webcam.


We’ll be carrying out essential work at Llyn Aled from 9 November until Christmas.

During this time, the Llyn Aled car park will be closed.

As part of the work, our team will also need to work on the road across the dam.

To keep our team and motorists safe, the road across the dam between the A543 to Rhyd-y-Bedd and Llansannan will be closed from Tuesday 24 November until the end of Friday 27 November. A diversion will be in place, so please allow extra time for your journey.

We’re sorry for any disruption and thank you for bearing with us while we carry out this essential work.

Fishing

Llyn Brenig lake is one of the best top-of-the water trout fisheries in the UK. With 23km of shoreline, the lake is stocked with rainbow trout for fly fishing and pike fishing in the winter. Anglers must book in advance.
