Walking trails

The ‘Wales Coastal Footpath’ runs along the sea wall and leads to a wooden screen that gives an impressive view of the wildlife on the estuary without disturbing them.

Access

This place is internationally important for the birds that use the foreshore and they are very sensitive to disturbance. Please keep to the footpath and do not attempt to walk on the foreshore as the mudflats are exceptionally dangerous. Cattle and horses roam freely along this stretch of coast, including on the lower path and on top of the sea wall.

About the reserve

This glistening landscape of rippling pools, marshy islands and mudflats stretches far out across the Severn Estuary. This tidal habitat is a difficult place to live but is perfect for specialist coastal plants, like sea aster, marsh mallow and sea milkwort.

It is the thick mud, teeming with invertebrates, which makes this place such a haven for wildlife, particularly the thousands of wading birds that use it as an important stopover to feed and rest during migration. Dunlins, turnstones and redshanks feast on the mud-dwelling creatures in spring and autumn. The haunting calls of curlews and the piping of oystercatchers fill the air and they are joined in the winter by ducks like teal, wigeon and shelducks.

What we do here
Gwent Wildlife Trust owns the fishing rights to approximately 2 km2 of the foreshore. We have an agreement with the Wentlooge Wildfowling and Conservation Association to have a no shoot zone at the mouth of the Peterstone Gout.

Directions
By car
Travelling west, leave the M4 at Junction 28 and at the roundabout exit onto the A48 towards Newport. At the next roundabout, take the 3rd exit, signposted ‘St Brides/Duffryn’. At the mini roundabout, take the 1st exit to continue along the B4239 to St Brides. Continue on for approximately 1.5 km after passing Peterstone Lakes Golf Club, following the road as it veers to the left and then the right. Park across the road from the church.

To reach the reserve, walk along the path by the church signposted ‘Sea wall’.
