Llyn Brenig is a man made reservoir situated in a large area of moorland between Denbigh and the A5. There a many possible rides in this area. The one described is a circuit of the lake and is approximately 10 miles long. There is a short section along a B road, but this isn't normally busy. The ride is described going round the lake in an anticlockwise direction, as route finding is easier this way.
From the Visitor Centre find the track that runs in a southerly direction along the side the reservoir. It starts opposite the cycle hire place. Cycle over the dam and follow the stone track along the reservoir. This leads through a short section of forest and finally onto a small lane. Follow the lane to the junction with the B4510 ad turn left onto the road.
This is where the uphill section starts! It isn't too steep but is fairly continuous. Eventually you reach the summit, where the map shows a parking place with picnic table. In April 2010 the table wasn't there, but the parking place is a good place to admire the view and recover from the climb.
There is now a nice downhill section, which leads to a T junction. Turn left and take the second forestry track on the left (the first one leads to a dead end). This descends down to the reservoir, where you can follow the shore back to the Visitor Centre. Be careful not to take any turns leading off to the right as these will lead you back to the B4501.
The Visitor Centre is open seven days a week between March and the end of October. There is a good cafe and an and outside play area for the children. They can be contacted on 01490 420463 or you can view their web site by clicking here .
