The Lakes Circular Walking Trail

The best of both worlds! This moderate walking trail combines both the Brenig Walking Trail and Alwen Walking Trails, with some spectacular views to be found.

Did you know that during the construction of the lake, a number of Bronze Age artefacts were found. The site was used as a camp by Mesolithic hunter-gatherers. This has been dated by radiocarbon analysis of the charcoal from their fires to around 5700 BC. You can follow a number of archaeological trails, the relics visible include a ring cairn (a Bronze Age burial mound), and several barrows!

From the Visitor Centre, head to the dam and then right up the hill towards the main entrance.


At the main entrance look right, then take care crossing the road and you will pick up the trail markers almost immediately for the ‘Lakes Link’ which will take you to the Alwen Car Park.

Head right from the car park following the circular trail markers, approx. 1 ½ miles in don’t miss the marker on your left that takes you through the woods to the shoreline!

Follow the shoreline path that will then take you through the woods and out the other side. Head right, picking up the trail markers for the circular route once again.

This trail, which is rough in places, will take you all the way back to the main road. Cross straight over and follow the path to the next junction. Turn right here. Follow this trail along side the lake back to the Visitor Centre.
