Top Beaches Day Trips from Cardiff

The top Beaches Day Trips from Cardiff include Llantwit Major Beach, Tresilian Bay Beach, Berrow Beach, Monknash Beach, Lilstock Beach, Kilve Beach, East Quantoxhead Beach and Minehead Beach.
Cardiff is lucky in its coast: within an easy drive the Welsh capital reaches both the dramatic cliffs of its own Glamorgan Heritage Coast and, across the Bristol Channel, the wide sands and fossil ledges of Somerset. To the west lie the Vale of Glamorgan shores, where Llantwit Major, Tresilian Bay and Monknash sit below tall layered cliffs, reached down wooded valleys.
Look across and around the channel and a different coast opens up in Somerset: Berrow, with its shipwreck on the sand near Burnham-on-Sea, and the fossil-rich rock platforms of Lilstock, Kilve and East Quantoxhead below the Quantock Hills. Further west again, Minehead marks the start of the South West Coast Path.
Some of these are family beaches with cafes and car parks; others are wild coves you can only reach on foot. All make a rewarding day out from the city.
Here are eight beaches for a day trip from Cardiff.

Llantwit Major Beach At the mouth of the Cwm Col-huw valley, Llantwit Major Beach serves the old town of the same name in the Vale of Glamorgan, on the Glamorgan Heritage Coast. When the tide falls it reveals sand and plenty of rock pools, set below tall cliffs of layered limestone and shale.
A cliff-top nature reserve runs west along the coast, and the beach draws both families and surfers. You will find a car park, a cafe and toilets here, and dogs are welcome through the winter months.
About 24km west of Cardiff, it makes an easy and rewarding first stop along this coast.
Tresilian Bay Beach

Tresilian Bay Beach Tucked between Llantwit Major and St Donat's, Tresilian Bay is a peaceful cove of pebble and rock on the Glamorgan Heritage Coast. Limestone cliffs riddled with caves rise behind it, and a stream threads down the valley to the sea.
Its best-known feature is a large cave with a natural rock arch, bound up in a local courtship legend in which couples toss pebbles up at the arch for luck. Most walkers reach it along the cliffs from the beach car park at Llantwit Major, as there are no facilities on the sand.
Some 25km west of Cardiff, it rewards those willing to go on foot.
Berrow Beach

Berrow Beach Across the Bristol Channel on the Somerset coast, just north of Burnham-on-Sea, Berrow Beach is a wide, flat sweep of sand backed by low dunes, looking over the tidal flats of Bridgwater Bay. Out on the sand lie the blackened ribs of the Nornen, a Norwegian barque driven ashore in a gale in 1897, her timbers now half-buried and rising like a skeleton.
The whole crew of ten was saved by the Burnham lifeboat, with no lives lost. A little dune-backed church stands nearby, and Exmoor and the Welsh hills rise across the water.
At low tide the firm sand seems to run for miles. Around 27km from Cardiff.
Monknash Beach

Monknash Beach Monknash Beach is a wild, undeveloped run of sand and rock on the Glamorgan Heritage Coast, backed by high, layered limestone cliffs. Nash Brook flows down the wooded Cwm Nash valley behind and spills over the rock ledges at the back of the beach as a small waterfall.
The only way in is on foot, about a mile down the valley, and at low tide broad flat sands and rock pools open out. The village takes its name from a medieval monastic farm that once supplied Neath Abbey.
There are no facilities on the sand, which is also known as Cwm Nash or Traeth Mawr. About 28km west of Cardiff.
Lilstock Beach

Lilstock Beach West of Kilve and Watchet on the Somerset side of the Bristol Channel, Lilstock Beach is a remote rocky foreshore below low, crumbling cliffs. The shore is a wave-cut platform of dark shale and pale limestone ledges, mixed with shingle, sand and mud, looking toward the island of Steep Holm.
Its rock beds date from the end of the Triassic and start of the Jurassic, around two hundred million years old, and ammonites, belemnites and even marine reptile bones have turned up here. It is a protected geological site.
A small car park sits back in the hamlet, with a short track to the shore. Roughly 31km from Cardiff.
Kilve Beach

Kilve Beach Below the Quantock Hills on the Bristol Channel, Kilve Beach is a rocky, fossil-rich shore on the west Somerset coast. Wide ledges of grey lias rock reach out below low cliffs, and the flat stones and shale give up ammonites and other fossils as they weather onto the beach.
Near the shore stands a ruined brick building, left from a failed scheme in the 1920s to make oil from the shale. A car park and path lead down to the sand.
Do note that the rock is protected ground and must not be hammered. Around 32km from Cardiff, it pairs neatly with neighbouring Lilstock and East Quantoxhead.

East Quantoxhead Beach Close to Kilve on the Somerset shore of the Bristol Channel, East Quantoxhead Beach is another rocky, fossil-rich spot. Low cliffs of grey Blue Lias, banded mudstone and hard limestone stand behind a wide platform of rock ledges that the tide draws back from at low water.
Ammonites weather out of the rock, and rock pools fill among the ledges, so it is a fine place for a slow scramble and a look at the geology. There is no parking at the beach itself, which is reached by a footpath down from the village.
At roughly 32km from Cardiff, it sits right beside Kilve for an easy double visit.
Minehead Beach

Minehead Beach Minehead Beach is the main shore of the Somerset resort town, a broad, flat beach that turns sandy toward the harbour and grows muddier and stonier elsewhere. Behind it runs the Esplanade, lined with old holiday hotels, and at one end sit the harbour, its boats and the Butlin's resort.
This is where the South West Coast Path begins, the long-distance route of some 630 miles down to Poole, marked on the quay by a 2001 sculpture of a pair of hands holding a map. With cafes, parking and plenty to do, it suits a family day.
About 36km from Cardiff, it is the furthest of these beaches.
FAQs
Which beaches are best for families near Cardiff?
Llantwit Major in the Vale of Glamorgan is the easiest, with sand, rock pools, a car park, cafe and toilets. Across the channel, Berrow near Burnham-on-Sea and Minehead in Somerset also offer broad sand and facilities.
Can you find fossils on these beaches?
Yes. The Somerset shore near Cardiff is rich in them: Lilstock, Kilve and East Quantoxhead all have rock ledges where ammonites weather out. Note that Kilve and Lilstock are protected ground, so the rock must not be hammered.
How far is the Somerset coast from Cardiff?
The Somerset beaches here range from about 27km at Berrow to 36km at Minehead as the crow flies from Cardiff, though the drive around the Bristol Channel by road is longer, so allow a good part of the day.
Conclusion
From the surf and rock pools of Llantwit Major to the ancient fossils weathering out at Kilve, this run of coast shows off two very different shores within reach of the city. Families will find easy sand, cafes and parking at Llantwit Major, Berrow and Minehead, while walkers and beachcombers can lose a day at quieter spots like Tresilian Bay, Monknash and East Quantoxhead.
Several beaches uncover their best features only as the tide falls, so it is worth checking the times before you set out and keeping an eye on the water on this big-tided coast. Pick a Welsh cove or a Somerset strand, allow for the drive around the channel, and you will see why these are the beaches for a day trip from Cardiff.
