Ynysgain is a beach of shingle and low-tide sand to the west of Criccieth. Most of it is backed by boulder clay cliffs which are showing signs of erosion. The Afon Dwyfor (river) emerges at the western end.
The easiest access is from Criccieth's Marine Beach - either along the (mostly level) coastal path, or along the shore. Dogs are allowed at all times.
The photos were taken 2 hours after high tide.
