Located in Swansea, a vibrant city boasting breathtaking beaches, one hidden gem stands out from the rest – Pwll Du Bay.

This secluded beach, nestled at the foot of a valley, is the least accessible in the city, only reachable via three scenic footpaths.

Despite the extra effort required to reach it, visitors swear that the experience is unmatched by the city’s other, more accessible beaches.

Pwll Du Bay’s unique charm lies in its stunning pebble bank, comprising thousands of pebbles, surrounded by towering limestone cliffs, all set within a picturesque and tranquil location.

The pebbles are arranged in a wavy pattern, resembling ripples from the sea, and are remarkably deep, forming dunes.

Pwll Du, translating to ‘Black Pool’, owes its name to a large pool formed behind the beach by a stream that filters through the pebble bank onto the shore, reports Wales Online.

According to Explore South Wales: “The bay is steeped in history having once been a haven for local smugglers.

There is a nearby gully called Graves End which is marked by a circle of limestone rocks, so called due to the burial of several people who were found dead on the bay following a ship called The Caesar ending up wrecked nearby in 1760.

“The Caesar was an Admiralty tender ship on a recruitment mission when rough sea conditions on the channel drove it against the headland of Pwll Du.

Although a few officers of the ship escaped with their lives, around 90 press ganged men all imprisoned below deck on the ship were not so lucky.”

“Later, during the 19th century, it was a centre for limestone quarrying and it’s these rocks that give it its unique topography. Near the top of the cliff on the west side is the now overgrown remnants of one of the quarries which is reportedly a fascinating place to explore if you can find a way to access it.

“There are two cottages situated on the western side of the beach known as Seven Slades, these cottages were originally inns called The Ship and The Beaufort.”

Access to the beach is limited to three footpaths – two along the coastal path from east or west, and the third through Bishopston Valley. The coastal paths offer superb views of the Gower coastline and sea, while the valley walk is an enchanted trek, meandering down through trees to a river which zigzags its way towards the beach.

The journey from the car park at Bishopston or Southgate to the beach is a challenging one, spanning over 400m and potentially involving rough terrain (SA3 2HL). The lack of wheelchair access and lifeguard patrols further complicates matters.

However, those who do make it can enjoy solitude, stunning sea views and the unique spectacle of the pebble dunes.
