Ffynnon y Wrach is virtually impossible to miss, a strange alien structure at the very side of the road beneath Holyhead Mountain as you ride up towards South Stack. An octagonal brick tower beneath a hemispherical rusted metal dome. Ffynnon y Wrach is generally translated as the Witches Well. The name dates back into antiquity the earliest date I have found of a written record being 1733; but there is no knowledge of the witch or witches to which its name might refer.

Fantastic views of the area and a good camping site set in 18 acres with panoramic views of the stunning Holy Island coast line, nearby beaches, coastal trails and wildlife spots, Blackthorn Farm is perfect for camping or caravaning. And with road, rail and ferry services within a 3 mile radius, it is the ideal base to explore Anglesey and North Wales. I wonderful base camp for cyclists

Malltraeth Cob Malltraeth is the next village along from Newborough to the north. The two villages are linked by a “cob” – a dike wall – with a footpath/cycle track along its top. The cob was completed in the early 19th Century, under the direction of Thomas Telford and John Rennie. At the same time, the Afon Cefni was straightened (and straitened) creating what looks like a canal, but is still tidal. This created nearly 1,600ha of grazing land on either side of the Cefni. Much of this land is now a nature reserve managed by the RSPB. Also you will see Llyn Parc Mawr Community Woodland where they have picnic areas where you can enjoyed the red squirrels. It is off road but I used my gatorskins and it was fine.

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.

It's marking a link which saw Holyhead play host to Dutch sailors at the start of the first world war. The soldiers came to the town after escaping the Nazi advance in 1940 The commemoration will see a Dutch Navy ship sail in to Holyhead harbour and a flypast by RAF jets.

The bridge itself takes the same name as the village it is situated in and is one of three bridges connecting Holy Island and Anglesey. The bridge is approximately four miles (6.5 km) from Holyhead via the old road route, giving it, and the village, its name. A bridge at this location was in existence by 1530, and was the only land route to Holyhead until the construction of the Stanley Embankment in 1823. It is 120 metres (390 ft) long and carries the B4545 road over the Cymyran strait. I think the crossing over the water is about 5km
