The section of the Anglesey shore opposite Caernarvon is known as Tal-y-Foel Beach (pronounced 'taller voil'). It's not what most people would regard as a beach though. The shore is mosly shingle and seaweed, with some small patches of coarse sand. The road runs along the seafront for about ⅔ mile with a parking area for about 6 cars which has good view towards the mountains of Snowdonia. There are no facilities except for a cafe at the Foel Farm Park.
The photos were taken at low tide.
