Abereiddi & the Blue Lagoon · 0 yards from Abereiddi
Black sand, a flooded slate quarry of improbable blue-green, and coasteering's most famous jump-off.
There are 8 beaches within about 5 miles of Abereiddi. The closest is Abereiddi & the Blue Lagoon, 0 yards away as the crow flies — further by road, because almost everything here is further by road.
Only one — Whitesands Bay (Porth Mawr) — has RNLI lifeguard cover, and only in season. Everywhere else on this list, you're judging the water yourself.
7 welcome dogs all year across the whole beach (Abereiddi & the Blue Lagoon, Traeth Llyfn, Aber Draw, Trefin and 4 others). Of the others, 1 restrict dogs from 1 May to 30 September. Signs at the access points are the authority, not us.
Parking is the constraint: only 3 have a mapped car park within half a mile, and in July and August those fill by mid-morning.

Black sand, a flooded slate quarry of improbable blue-green, and coasteering's most famous jump-off.
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.
A sheltered working-harbour cove between Trefin and Mathry — kayaks, crab lines and a 5,000-year-old tomb up the hill.
A storm-built pebble bank with woodland and marsh behind, and firm sand appearing only at low tide — quiet, moody and rarely busy.
The drying harbour at the head of Solva's ria — boats on the mud, crabbing off the wall, sand at low water.

St Davids' big Blue Flag surf beach beneath Carn Llidi — sand, swell and sunsets at the end of Wales.
The quiet cove ten minutes north of Whitesands — sand at low tide, no facilities, and currents that deserve respect.
