Holyhead Breakwater is situated at the north-western end of Holyhead in Anglesey. The Victorian structure, which is 1.7 miles (2.7 km) long, is the longest breakwater in the United Kingdom. The breakwater, which is accessible in good weather, has a promenade on top which leads out to the Holyhead Breakwater Lighthouse. It can be very slippy where the water comes around and moss has grown. Not ideal to ride over in bad weather.

The Stanley embankment is known locally as The Cob, it joins Anglesey to Holy island. The cob is basically the old A5 road and rail link to Holyhead. When travelling on the newer A55 to Holyhead it can be seen to the right as you cross the inland sea. The Cob creates a pinch point where the vast tidal forces push the water through at high tide. At low tide it a vast expanse almost devoid of water.

The sharp drop down on the coast road from the north can be taken at speed to swoop into the dip behind the beach and up again over the short climb out.

Traffic tends to floor it along the straight embankment road so it’s worth using the adjacent cycle path. On Holy Island though it’s better to return to the road as the cycle path runs is narrow and covered in debris from the overhanging trees.
