Traeth Bach, Cemaes Bay

Cemaes, Isle of Anglesey · LL67 0ET

Small shingle-topped beach on the west side of Cemaes harbour, Anglesey's most-reported sea glass spot, with blues and black among the finds.

About Traeth Bach, Cemaes Bay

Traeth Bach is the smaller of Cemaes's two beaches, on the western side of the harbour across the Afon Wygyr from Traeth Mawr. It is sandy with a shingle top and rocks at each end. The village was a working port that shipped china clay, bricks and ochre and had a shipyard, and collectors describe the beach as one of the best for glass on Anglesey.

Sea glass at Traeth Bach, Cemaes Bay

Collectors report white, green and amber as standard, with soft blue, aqua, dark olive, cobalt, turquoise and black turning up, plus sea pottery. Work the shingle line and harbour-wall shingle as the tide drops, then the rock pools at either end; the strandline is freshest after westerly or winter storms.

Visiting Traeth Bach, Cemaes Bay

Getting there
Traeth Bach is on the western side of the harbour; cross the bridge over the Afon Wygyr from the village. Buses 31, 60, 61 and 62 serve Cemaes (check timetables).
Parking
Village car park a couple of minutes' walk behind the beach. The main Traeth Mawr car park (Ffordd y Traeth, LL67 0ES) charges in season; there is also a free public car park off the High Street.
Toilets
Public toilets (including accessible) in the main Traeth Mawr car park, and on the High Street next to Oriel Cemaes Gallery.
Safety
Check the tide times before you go and head out on a falling tide, so you're never cut off. Keep away from the bottom of cliffs, wear sturdy shoes on rocks, and only take sea glass and other man-made rubbish: pebbles, sand and shells should stay on the beach.
