More information about Green Castle Woods

This mix of ancient and newly created woodlands, botanically rich meadows and hedgerows provides a haven for wildlife. The Carmarthenshire Coast Long Distance Footpath is routed through the site and fine views can be had over the Afon Tywi and towards Carmarthen.

This is a great place to visit whatever the time of year, with huge diversity and so much to see across the 125 acre (50.5 ha) site. In fact, Green Castle Woods is not just one but three woods - two ancient oak woods and a more recently planted woodland consisting of birch, ash, alder and willow.

There are also hay meadows which are filled with wildflowers and butterflies throughout spring and summer; plus an area of wet pasture, ponds, a stream lined with willow and alder, and a delightful waterfall, which provide homes for rare plants and mosses. The whole wood is criss-crossed by centuries-old hedges and walls, and sunken lanes.

On three sides the surrounding countryside is made up of relatively small hedged fields of permanent pasture and small widely separated woods, which together create a very attractive undulating landscape; whilst the northern boundary rises to a high point of approximately 250 feet from the western bank of the Afon Tywi (River Towy), part of the Carmarthen Bay and Estuaries Site of Special Scientific Interest, with open views over Carmarthenshire and Green Castle itself.

Changing seasons add variety as well. In spring there are carpets of bluebells, wild garlic and wood anemone. In summer look out for grassland flowers such as fleabane, sneezewort and flag iris and also lizards sunbathing. In autumn there’s wonderful autumnal colour, toadstools, and blackberries which visitors are welcome to pick; and in winter the waterfall is at its best.

There is an extensive network of footpaths throughout the site, connecting to the Carmarthenshire Coast Long Distance Footpath, and fine views over the Afon Tywi and towards Carmarthen.

Access and walks

There are three ways into the woods from the car park, all of which are signposted. Look out for a special route to the left for the less able and those in wheelchairs, and a diversion to the right for dog-walkers that connects with the main trail 220 yards further on. The main Wild about Woods circular trail is straight ahead but isn’t suitable for wheelchair users or pushchairs. And there are some wet bits so sensible shoes are a must in wet weather. It takes about an hour to walk round, while the surfaced route take approximately twenty minutes.

The wide kissing gate on the left of the car park leads to a short, circular, easy path through an area that’s almost a perfect miniature of Green Castle Woods. There are also a couple of lay byes with short benches and pull-in spaces for wheelchairs.

Two other entrances can be found off the B4321, and a further entrance where the Carmarthen Coast Path enters the site at the South East corner – all accessed by stiles.

In addition to the Wild about Woods circular train, there is an extensive network of footpaths through the 125 acre (50 ha) woods, including the Carmarthenshire Coast Long Distance Footpath which crosses the site. These footpaths may include steps, footbridges and boardwalks, and some of the paths on the east side of the road go through fields which are grazed by cattle.


Green Castle Woods sits on both sides of the B4321 in Carmarthenshire (Sir Gaerfyrddin) in Wales, and runs down to the River Tywi. It is approximately 3.5 miles out of Carmarthen towards Llansteffan, with IIangain the nearest village at approximately one mile away along the same B4321. The site connects on one side to the western bank of the Afon Tywi (River Towy), an estuary feeding into Carmarthen Bay.
