St. Cybi’s Church in Holyhead, Anglesey, was founded in the 6th century by Saint Cybi. Surrounded by ancient Roman fort walls, it features architecture from the 13th to 16th centuries. Still an active parish church, it offers visitors a glimpse into Wales’ medieval history and unique religious heritage.

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.

Ty Bach was built new in 2015 and offers unbelievable cliff top sea views along with views of Dafrach and Treaddeur. Just a 2 minute walk from the door and you’ll see South Stack lighthouse in all its glory and could visit the RSPB coffee shop and visitor centre. It’s a paradise for those who love views of the sea, wildlife and getting away from it all. It's a fantastic place to stay if you enjoy cycling or hiking and it's one of my favourite to use as your home base. It has beautiful windows and you can catch the sun. Very relaxing when you get back from a long ride.

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.
