Ynys Gifftan
Ynys Gifftan is an island near the south east shore of Traeth Bach, the Dwyryd estuary near Portmeirion in Gwynedd, north Wales. There is a public footpath to it across the estuary marked on Ordnance Survey maps but has no definable marks that make it obvious; it can be reached on foot at low tide and is high. The island has been uninhabited since the mid-1960s and the island's single cottage is in a state of disrepair.
It is one of 43 tidal islands which may be reached on foot from the mainland of Great Britain.
