Walk details
- Start at the reservoir car park. Follow the road alongside the reservoir and pass through the gate. Just after the gate there is a path down to a viewing point at the waterside from which you can see most of the reservoir. Continue on the road alongside the reservoir passing the old colliery until you reach Pont Gerdded.
- Here you have the option of continuing your walk along the opposite bank of the reservoir or turning back along the road. The route on the opposite bank is a narrow footpath with a steep drop to the water on one side and has a rough surface in some sections where tree roots and uneven ground must be negotiated. There are a number of benches where you may stop for a rest.
- If you are walking the opposite bank, turn left through a kissing gate and down some stone steps to a picnic area then cross the footbridge over the Afon Lliw. Follow the path until you reach the dam then across the dam back to the car park.
Highlights
- The dam holding the Lower Lliw reservoir was completed in 1867. However it was never completely watertight, a situation that was corrected in 1979 when it was rebuilt – 112 years after first being constructed. The reservoir originally supplied water to Swansea, but these days after being treated at the nearby Felindre Water Works, water is pumped all over South Wales.
- Coal mining was once active in the area and the walk passes one of the buildings of the Felindre Colliery, disused for over a hundred years.
