Pembrey Beach - Llanelli (Cefn Sidan)

Pembrey is a long, wide, unspoilt, sandy beach, backed by sand dunes, stretching for approximately 8 miles.  It lies within Pembrey Country Park and offers views across Carmarthen Bay to the hilly coastline on the other side.

The beach is particularly popular for activities such as swimming, and watersports, and its length and width make it an excellent place for visitors to stretch their legs between the ocean and the forested country park.

The country park itself spans over 500 acres and includes many trails for both walking and mountain biking, a number of ponds which can be havens for wildlife, and is scattered with old defences and pillboxes from World War Two. The park also offers many more facilities to visitors including a dry ski slope, a toboggan ride, crazy golf, pitch and putt, train rides, an adventure play area, and an equestrian centre.

A wetland ecosystem, known as Pembrey Burrows can be found behind the eastern end of the beach, and is a good destination for bird watchers.

The country park has a large car park from where the beach can be accessed along a path crossing the sand dunes. Public toilets can be found along this path, as well as a cafe.

Some further facilities can be found in the village of Pembrey, about a mile away. The nearby, larger town of Burry Port contains a greater selection of shops and places to eat, as well as a railway station.

Aside from walking, golf is also a popular pastime in the area, with a number of clubs close to the beach.

Super De-stressing place. Not populated in any way. Beautiful Beach

Best place I’ve been in Britain. People are saying there are a lot of bad people but we only saw dog walkers and families.

Tranquility restored

approach by bike if you can along millennium coastal path from lively burryport harbour with new lifeboat station, cafes and famous lighthouse.  you will be rewarded with 8 miles of stunning wild beach.  so wide and long and beautiful. you can give the country park commercial centre a skip and enjoy a magical day if you prefer wilderness and quiet or travel in for a coffee if preferred. Bliss!

Horrible area

I would not recommend. Full of garbage everywhere and lots of timewasters (alcoholics and homeless people ) in Llanelli. Sorry but won’t ever go or recommend to someone.

What did we get wrong?
