The walk begins at St Mary's Church, Marshfield. After passing through the graveyard, the route follows a mixture of grassy tracks, field-paths and quiet lanes as far as the Church of St Bridget, with distinctive leaning tower, in St Brides Wentlooge. The flat, fertile fields between the two villages, each drained by ditches known locally as reens, are more reminiscent of the Netherlands than a typical Welsh landscape. As in much of the Netherlands, this is reclaimed land: prior to the construction of the reens and sea wall, the Gwent Levels would have been a salt marsh regularly inundated by the sea. (It can still be a wet area and mud may be a problem on some paths).

From St Brides, it's a short distance to the sea wall which, with a break at the River Usk, stretches for over fifteen miles from a point just south of Chepstow to the eastern edge of Cardiff. Testimony to the wall's importance can be found on plaques commemorating a disastrous flood in 1606 (January 1607 by modern dating) in the churches of both St Brides and Peterstone. Caused either by a storm surge or a tsunami, a wall of water overflowed the rudimentary sea defences of the time, drowning people as far inland as Marshfield, almost two miles from the sea.

Along the sea wall towards Peterstone Wentlooge is Peterstone Gout, the main drainage outlet for the levels between Cardiff and Newport. (The River Usk splits the Gwent Levels into two distinct parts: the Wentlooge Levels to the west of the river and the Caldicot Levels to the east). Mud is the main feature of the landscape to your left (though suprisingly, there is a small sandy beach near St Brides just above the high tide line). The whole area provides a valuable habitat for a number of species of wading birds.

Just under a mile after crossing Peterstone Gout, the route heads inland towards Peterstone Wentlooge Church, whose impressive tower dominates the tiny village. (The 'Wentlooge' part of the village's name, which it shares with St Brides Wentlooge, is an anglicisation of Gwynllwg, the traditional Welsh name for the area between the Rivers Rhymney and Usk). After a short section along the B4239 (no pavement), the route crosses fields and a main railway line to reach the edge of Marshfield. Unfortunately, the continuation of the right of way was blocked at the time of writing by impenetrable undergrowth at both ends of the path between the main road through the village at ST 258823 and the start and finish point at Marshfield Church. As a result, the present route follows St Mellons Road and Church Lane to return to the starting point.

First time I have used the app. Very impressed. Did this walk 16.1.22, and enjoyed it. Two points to note though: At point 8 the path is impassable - overgrown with brambles and impassable. Walked on to the next lane and carried on. Back in Peterstone Wentlooge the Six Bells pub is now closed and boarded up.

This walk was taken offline whilst works were in progress but we expect them now to be completed. Please inform Walkingworld if there are any issues with it.

Did the walk on 24 March 2013. The walk was very muddy in places and this, coupled with the fact it was a bitterly cold, grey day, probably resulted in a lower classification than it deserves! The bridge over the railway (between Points 6 and 7) was closed because of renovation work - we were able to get through only because it was a Sunday and no activity was in progress (we had to climb over gates and move barriers to squeeze through). We completely missed the track at Point 7 (we didn't see the red and white warning poles, but these may have been removed during tree pruning operations along the lane; the two turnings we found both had locked gates into fields and didn't match the photo), so stayed on the road round to Point 11, where we re-joined the route. In general, however, the walk was easy to follow. St Peter's Church in Peterstone Wentlooge is now a private house, so don't plan to have a lunch or coffee stop there!
