Cemlyn shingle ridge walk

Walking trail

Step out of the car park onto a fantastic shingle ridge, watch a host of water birds on the lagoon and walk back along the lane.

On this walk you'll pass the home of the first person to fly from Wales to Ireland, Captain Vivian Hewitt, who also created the lagoon. Please note that Bryn Aber car park and the bridge leading across to Esgair Gemlyn is liable to flooding. Please check for high tide times before your visit.
