From the car park, turn left along the cliffs until you find the corner looking over Colywell, this is a crag, called “The Crag” or “Crag Point” and can be fished at high water when there’s not too much movement.
Down the steps to the right of the car park leads to Hartly, which can also be a reasonable spot at high water. At low water you can get on to the Crescent rocks to the south side of the bay; the skeer to the north looks OK but I’ve not had much from there.
If the tide is big, you can get onto the Hartly Island in front of the bay by going over the rocks to the south side. Watch your back as the tide floods and the island gets cut off. All the low water marks are exposed and not somewhere to fish if there’s any swell.
