Porth Cae-du (above) is a cove of sand and rocks on the south side of Holy Island, and just a short walk from the much busier Borthwen, and a good place to escape the crowds. Porth Gorslwyn is just to the east, and is mostly pebbles with some low-tide sand.
The names Porth Cae-du (pronounced 'kiy dee') and Porth Gorslwyn (pronounced 'gorse-lewin') translate as 'Black Field Cove' and 'Cove of the reeds'. The photos were taken an hour after low tide.
