Llandegfedd Reservoir

Llandegfedd Reservoir is the largest inland water body in Gwent, covering some 174 hectares.  It lies near the village of Coed-y-Paen, about 3 miles east of Pontypool and consists mainly of open water with some reedbeds and willow carr at the northern end.  This northern, shallower end is the best area for wintering wildfowl while rare grebes and divers may occasionally be found in the deeper water in the middle.  The winter gull roost is impressive, in some years attracting rare species, whilst Osprey is regular in passage months.

Views can be obtained from the fishermen’s car park at the northern end or from the dam at the southern end.  Three hides are situated at the northern end and one near Sluvad Water Treatment Works south of Sor Bay – see map below.

The site is designated as an SSSI for wintering wildfowl and in order to avoid disturbance there is no access to the footpath on the east side between 1stOctober and 28thFebruary.

During the summer open season the gate to the northern fishermen’s car park will be open from 8.30am and locked at 5.30pm daily


Birdwatching permits

Permits are required if visiting between 1st October and 1st March. They can be purchased from the Welsh Water Visitor Centre located at the dam end of the reservoir at a cost of £8.00.

For entry to the northern end during the winter months you will need a key for the car park gate.  The keys cost £6.00 and can be obtained from the Visitor Centre at the same time as the permit.  If you already hold a key from a previous year you do not need a new one.

Refreshments are available at the Welsh Water Visitor Centre (Tel: 01633 373401 for opening times).

To reach the fishermen’s car park on the northern shore drive to Jerusalem Lane (as above) but ignoring the right hand turn signposted Llandegfedd Reservoir, carry straight on for about 4kms.  Turn right at a crossroads in Glascoed Village, into the road marked with a ‘No through road’ sign.  The car park will be reached in about 500m.
