Beaches near Trefin

Aber Draw, Trefin
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.
Traeth Llyfn
A big sandy cove between Abereiddi and Porthgain, reached by a steel staircase bolted to the cliff — and cut off at high tide.
Abereiddi & the Blue Lagoon
Black sand, a flooded slate quarry of improbable blue-green, and coasteering's most famous jump-off.
Abermawr
A storm-built pebble bank with woodland and marsh behind, and firm sand appearing only at low tide — quiet, moody and rarely busy.
