A popular seaside resort on the eastern coast of Anglesey. The derivation of Benllech's name is a matter of some doubt. It is agreed the name comes from Pen llech, or the head of the slab or rock. One school of thought says this refers to the wave cut platforms at the foot of its cliffs, whilst another considers it to be a reference to a pre-historic burial chamber. It is certainly the case that there are a number of ancient burial sites around Benllech, most notably Pant y Saer.

Benllech is noted for its expanse of golden sands, which gently shelve into the sea, making for safe bathing. In addition to its attractiveness to holiday-makers, Benllech is a popular location for retirement. There is a nine hole golf course at Storws Wen, on the road to Llangefni.
