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 wide 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 are to be had over the Afon Tywi and towards Carmarthen.


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.
