Ynyslas Beach (pronounced 'unniss-lass') has sand at low tide backed by a shingle bank. There are sea defences in the form of groynes and a wooden barrier at the top of the shingle bank which has to be climbed over to reach the beach. The beach is backed by dunes to the north, and by a golf course to the south.
Parking is at an attended car park, but there are no toilets. 'Ynyslas' translates as 'Blue island'.
