Two Lakes cycle trail — Llyn Brenig

Gravel riding

The longest of the seven waymarked cycle trails at Llyn Brenig, the Two Lakes trail takes in both the western shore of Alwen Reservoir and the eastern shore of Llyn Brenig, and combines forest fire roads, twisting singletrack, open moorland expanses and multiple nature reserves with jaw-droppingly beautiful views.

You’ll definitely need to pack the snacks for this longer loop, as it’s likely to take a whole morning or afternoon.

Start by making your way to Alwen Reservoir, following the yellow Two Lakes markers, which lead you past Llyn Brenig, up the gravel track to cross the main road, into the forest on a narrow singletrack and down to the reservoir’s shore on a fantastic gravel road descent.

You’ll ride over the grand Alwen Dam to reach the western shore. The trail alternates between wider gravel tracks with open views over the water and narrow, twisting singletrack trails.

After passing through a gate, you start climbing on a rougher track up onto moorland, the highest peak of the Denbigh Moors visible ahead of you. The track narrows until you’re following a slither of singletrack between the tussocks of grass, and the higher you get, the greater the view of the upper Alwen Reservoir is revealed. Soon you can see the bridge over the water that you’re yet to cross, and the bewildering expanse of moorland that lies ahead. It really does feel wonderfully remote up here.

A more technical descent warrants the use of a mountain bike, leading you down to cross the reservoir on the long, narrow wooden bridge. Start to climb when you reach the other side, which surprisingly leads you along a stone wall and towards farmland. Pass by farm machinery and grazing fields as you take a direct line towards the north of Llyn Brenig.

A singletrack section through ​​Hafod Elwy Moor nature reserve is a highlight, as is the forest trail that follows. Over the main road, you continue your dead straight line on a narrow singletrack descent that meets the road over Pont Brenig, before ramping upwards again as you climb Bryn Maen.

The singletrack through another nature reserve, Gors Maen Llwyd, is even better than the last, on flowing gravel with a mega view to your right of Llyn Brenig. The final stretch is a wide gravel doubletrack down the eastern shores of Llyn Brenig, then over the dam and back to the visitor centre. Lunch, anyone?

Alwen Dam

Highlight • Monument

The grand, ornate stone dam of Alwen Reservoir couldn't be more of a contrast to the neighbouring Llyn Brenig Dam. It's well worth taking a minute or two to take in this magnificent feat of engineering, that was completed in 1920. The reservoir here was built to provide drinking water for Liverpool and the Wirral.

View of Alwen Reservoir

Highlight • Lake

This is the high point of the circular Alwen trail around Alwen Reservoir.

Enjoy the wonderful views in nearly all directions, which really is a great reward after the long climb.

It feels remote up here, and a brilliant off-road singletrack descent is up next down to the bridge.

Alwen Reservoir Wooden Bridge

Highlight • Cycleway

A long wooden bridge spans the upper reaches of the Alwen Reservoir, which features on the Two Lakes and Alwen circular cycle routes. It's absolutely covered in lichen and feels a little rickety as you ride along. Enjoy the remote lake views as you ride over this long, narrow bridge.

11.0 km

A quieter stretch of bridleway connecting the Brenig and Alwen reservoirs. The track is relatively smooth and quite flat, though can sometimes be pretty muddy after rain.

Cairn Ben Lloyd Singletrack

Highlight (Segment) • Cycleway

A fantastic section of singletrack as you wind your way through Gors Maen Llwyd nature reserve to the north of Llyn Brenig. The undulating trail features on the Two Lakes and Brenig marked cycle routes.

Look into the distance when you rejoin the road heading west to east and you may be able to see the ridge of the Clwydian Range and the sea beyond.

Llyn Brenig — East Shore Gravel Track

Highlight (Segment) • Trail

A long and winding doubletrack gravel road that flanks the eastern shore of Llyn Brenig.

It's a little rough in places so best on a gravel bike, sturdy hybrid or mountain bike rather than a pure road bike.

Enjoy the views as you meander around the little inlets and see what wildlife you can see across the water.

Llyn Brenig Dam

Highlight (Segment) • Structure

Crossing over the top of the Llyn Brenig dam you'll follow a wide and flat gravel track that makes for an easy ride while you soak in those marvellous views over the water and down the bank on the other side into the lush green valley.

Look out for the fingerposts with trail markings to help you navigate onto your preferred route. You may be surprised just how long it takes to cross here, I thought it was further than it looked!

Llyn Brenig

Highlight • Viewpoint

You can find some glorious views here on the edge of Llyn Brenig. Llyn is Welsh for lake.

The dam is fairly recent; it was begun in 1973 and finished in 1976. It maintains the flow of water to the River Dee, not to be confused with the river of the same name in Aberdeenshire.

The water supplied by this reservoir feeds into North-East Wales and North-West England, including the Liverpool area.
