Measuring approximately 900m in length, the bay is sandy, backed by an extensive dune system, with limestone cliffs on either side. Situated on the south west coast of Anglesey, the bay is considered to be fairly remote, due to its 1 kilometre proximity from the nearest road way. The dune system is protected and listed as a Special Area of Conservation, with the beach area making up part of the Tywyn to Aberffraw Site of Special Scientific Interest, confirming the high conservation status of the Area. The site also lies within the Anglesey Area of Outstanding Natural Beauty.

Important! Tide times are for the nearest measurement point and may not be accurate for this location. You should not rely on these times for anything other than a broad indication of when the tide will be at its highest or lowest.
In particular, these tide times are not suitable for navigational use. Accurate tide forecasts require complex calculations and detailed local information. If you intend to engage in any activity for which tidal information is important for safety reasons (including sailing, powerboating, diving, and surfing) then you should obtain professional data.
