This has been pinned in the wrong place! The arch where this is pinned is Bwa Ddu. The picture is labelled correctly but should be located north of Porth Swtan

Just view stept below the café this viewpoint provides a varying scenery - from the lighthouse over the cliffs of Red Walls (with some climbers on them if you are lucky) and large bird colonies all over the place. The café itself is also worth a visit and the people there will advise on where to go as well.

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 lighthouse has warned passing ships of the treacherous rock below since its completion in 1809. The 91-foot (28 m)-tall lighthouse on South Stack was designed by Daniel Alexander and the main light is visible to passing vessels for 24 nmi (44 km; 28 mi), and was designed to allow safe passage for ships on the treacherous Dublin–Holyhead–Liverpool sea route. It provides the first beacon along the northern coast of Anglesey for east-bound ships. It is followed by lighthouses, fog horns, and other markers at North Stack, Holyhead Breakwater, The Skerries, the Mice, Point Lynas, and at the south-east tip of the island Trwyn Du. The lighthouse is operated remotely by Trinity House. You can only go so far with your bike due to the 400 steps you must take to reach the lighthouse itself. We managed to lock our bikes up and tackle the stairs. But on the way back we realised it was too much and legs were tired 😫
