Llansteffan has long been a favourite with locals. According to the , it was a popular destination for Rhondda miners and their families in the 19th and 20th centuries, who would travel west for their summer break.

One of the main attractions is Llansteffan Castle, a beautiful ruin that sits high above the village.

The site was first used as an Iron Age fort, dating back to around 600BC, and was later fortified by Norman invaders shortly after 1100.

Over the centuries, the castle was captured and retaken several times during battles between the Welsh and the English.

The twin-towered gatehouse still stands, and the views from the top stretch across the estuary and surrounding countryside.

According to the official , the site passed through the hands of several families before eventually being granted to Jasper Tudor, uncle of King Henry VII.

Today, visitors can reach the castle on foot by following a path up the headland.

As well as its history, Llansteffan is known for its peaceful surroundings and two beaches.

The main beach is wide, sandy and great for swimming or long walks.

Just around the corner is Scott's Bay, a more secluded spot backed by cliffs made of red sandstone and siltstone.

The village is also popular for its walking routes and wildlife.

According to the , visitors can spot local birds, enjoy headland trails and take in the relaxed community vibe.

As the Tourist Association puts it: "Once you've witnessed the magical beauty of a sunset over the castle it's hard to imagine how you ever missed such a hidden treasure."
