River Trothy


The River Trothy is a small trout river with steep banks in many areas and overhanging tree growth making fishing difficult. However, it has Mayfly in abundance in May and June and offers a real casting challenge to the fly fisher with a light rod. The waters are permanently coloured.

M&DAS rent 3 km of right bank from the field below Jingle Street bridge up to Dingestow Bridge. We also rent 3.2 km of right bank above St Dingat’s church in Dingestow to the orchard of lower Llantrothy farm.

We also rent approx. 500 metres of left bank from the Treowen Estate directly opposite Lower Llantrothy farm which can be accessed over a footbridge below Llantrothy Farm orchard.

The best fishing spots

Access is often easiest from the fields just below and just above Jingle Street bridge. The bankside immediately above St Dingat’s church, and the bankside at Lower Llantrothy Farm and at Treowen Estate opposite, are also excellent as the tree growth here is cut back and managed. The vegetation on all banks can be a nuisance and requires regular strimming.


Access at Jingle Street: Leave Monmouth on the Wonastow Rd and travel for approx 2.5 miles. Jingle Street Bridge is on the left.

Continue past Jingle Street to Dingestow. At the tee junction turn right then right again to the Church car park. For access to Lower Llantrothy continue past church for 1 mile & turn right at top of brow behind white bungalow. Park just before farm entrance off the driveway. Pedestrian access is allowed through the farm.

Note: River banks are designated Left and Right looking Downstream
