The confluence of these three broad estuaries forms an intertidal area covering thousands of acres on the shores of Carmarthen Bay and is one of the most important areas of such habitat in South Wales.

As well as sandbanks and mudflats there are large areas of grassland, saltmarsh, and numerous creeks.

Outside the estuary mouth are the fine sandy beaches of Laugharne Sands and Pendine Sands to the west and Cefn Sidan Sands to the east. Salmon Point Scar on the north of the Gwendraeth Estuary has a rocky beach and on the opposite shore at Wharley Point where the Taf meets the Tywi there are cliffs.

Behind the dunes of Cefn Sidan Sands is Pembrey Forest,[Map] a large area of pinewoods that has great interest for botanists and entomologists.


Notable Species

Great Cormorant breeds on nearby St Margaret's Island and gathers in large numbers in the estuary and Grey Heron is another locally breeding bird that is always present. Other species seen throughout the year include Common Shelduck, Common Eider and Common Scoter, and Oystercatcher and Ringed Plover which breeds in small numbers. Common Buzzard is a frequent hunter over woods and grasslands.

Ornithologically the area is of most interest in winter and during passage periods. In midwinter various divers and grebes can be seen as well as waterfowl including Eurasian Wigeon, Common Teal, Northern Pintail, Common Goldeneye and Red-breasted Merganser.

Waders include large numbers of Red Knot, Sanderling and Dunlin as well as godwits, Greenshank and Eurasian Curlew.

Twite and Snow Bunting are sometimes present in winter.

During passage periods a wide range of waders can be seen in the estuary, particularly in late summer-autumn when the greatest variety occurs. Wildfowl numbers begin to build up in late September-October.

The resident Common Buzzard are sometimes joined by Merlin, Peregrine Falcon and Hen Harrier, Short-eared Owl and Great Grey Shrike in winter and Northern Goshawk is possible in Pembrey Forest.


Rarities recorded in this area have included Surf Scoter, Common Crane and Eurasian Spoonbill, Cream-coloured Courser and waders such as Long-billed Dowitcher, Grey Phalarope and Buff-breasted Sandpiper, Baird's Sandpiper and White-rumped Sandpiper.

Sabine's Gull, White-winged Black Tern and Little Auk have also been recorded.

Other Wildlife

Pembrey Forest [Map]and the adjacent dunes are rich in invertebrates with more than 30 species of butterfly to be seen including Silver-washed Fritillary and Marbled White. Other insects include a variety of dragonflies, damselflies and grasshoppers as well as rare species of soldier-fly and longhorn beetle.

Plants of interest include Moonwort and Adderstongue, Lesser Water-Plantain, Bloody Cranesbill and Twiggy Mullein. Orchids are rich and diverse with Bee and Fen, Pyramidal, Fragrant and Green-winged, Autumn Lady's Tresses and Marsh, Dune and Broad-leaved Helleborines. Dune Gentian is a local speciality.

Site Information

The area is worth visiting at any time of year but summer weekends and public holidays can be rather crowded.

History and Use

Much of the southern shore is a military area and access is very difficult but Tywyn Point can be reached via Pembrey Forest and Cefn Sidan Sands.

Areas of Interest

The Tywi Estuary can be viewed from Llanstephan on the western bank and Ferryside[Map] in the east. To the south of Ferryside there is a minor road to the rocky shore at Salmon Point Scar.[Map]

Continue on foot from here to explore the northern shore of the Gwendraeth or drive to Cydweli Quay[Map] for the head of the estuary.

For the Taf Estaury one of the best spots is Ginst Point,[Map] reached on foot from Laugharne via Sir John's Hill and the sea-wall.

A possible alternative is to take the A4066 Laugharne to Pendine road and follow the MOD boundary fence towards the point.
