Traeth Llyfn · 900 yards from Porthgain
A big sandy cove between Abereiddi and Porthgain, reached by a steel staircase bolted to the cliff — and cut off at high tide.
There are 4 beaches within about 5 miles of Porthgain. The closest is Traeth Llyfn, 900 yards away as the crow flies — further by road, because almost everything here is further by road.
None of them has RNLI lifeguard cover. That doesn't make them dangerous, but it does mean nobody is watching the water, and this coast has rip currents and a big tidal range. Swim where you can stand, and dial 999 for the Coastguard if anything goes wrong.
1 welcome dogs all year (Abereiddi & the Blue Lagoon); the rest restrict them from 1 May to 30 September. Signs at the access points are the authority, not us.
Parking is the constraint: only 1 have a mapped car park within half a mile, and in July and August those fill by mid-morning.

Dog restrictions and lifeguard dates are set locally and do change. The signs at the beach access points are the authority — not this table.
A big sandy cove between Abereiddi and Porthgain, reached by a steel staircase bolted to the cliff — and cut off at high tide.

The rocky cove below Trefin, with the ruined mill on the shore — a five-minute walk from the village and no sand to speak of.
Black sand, a flooded slate quarry of improbable blue-green, and coasteering's most famous jump-off.
A storm-built pebble bank with woodland and marsh behind, and firm sand appearing only at low tide — quiet, moody and rarely busy.
