Church Bay is so called because of the nearby St Rhuddlad's Church, Llanrhuddlad which is visible from the bay.

A beautiful viewpoint, small paths, a bit up and down, easily doable.

The ruins are fenced and not directly accessible (probably more to keep the sheep out), but they put up some benches nearby for a break with a view over the sea.

Lovely views from a height that looks down on Porth Padrig beach and surrounding area. Path is OK, but can have some grass growing in the centre. Nice and quite road heads in the direction of Llandadrig.

Cemaes Bay truly is a lovely everyman village with a pretty little harbour and two beaches. Both beaches are perfect for all manner of fun beach activities, Sailing, Windsurfing and Surfing. The Fishing can be excellent along the coast behind St Padrig's Church along the headand on the Llanbadrig Ledges. Then, there is the absolutely staggering Anglesey Coastal Path leading to the east towards Bull Bay, Amlwch and all the way around again. This portion of the Anglesey Coastal Path around Cemaes Bay really does take your breath away. More or less everything that has been weighing heavy on your mind and heart dissolves away to a pleasant state of tranquil reflection.
