Grade 1 walk from Four Mile Bridge estuary and along the wooden board walk next to the salt marshes with an abundance of birdlife. On through the fields and woodlands and onto a well defined path that takes us through a delightful pine plantation on the approach to Silver Bay, with its powdery white sands and view over to Rhosneigr and Snowdonia (through the height of the season a beach bar/ cafe is open).

We now take the designated coastal path that takes us on to Rhoscolyn with its blue flag awarded bay with an abundance of rock pools and safe bathing. Rhoscolyn Bay has views to Ynys Traws Island and the Beacon rocks, with an old beacon on the highest rock. The sea here is renowned for fishing for Pollock, Sea- Bass, Whiting and Dog Fish and diving in the crystal clear waters.

After a walk along the bay with its soft sands and rock pools, we ascend through carpeted squill and thrift bounded a mile long uniform stone wall on the landward side and cliff edges on the left. On ward to the National Coastguard Institution building with its panoramic view and which is run by 30 volunteers every day of the year. This breath taking view of the beaches of Holy Island stand out like gems among the rising cliffs.

Further on our walk to the dramatic and natural two arches. Bwa Gwyn which is the white Holyhead quartzite rock with shows massive fractures and deep weathering from the sea and 200 metres further the Bwa Du which is the black arch adjacent to a sea cave. This area is an attraction for the wild birds that include Chough, Peregrine, Falcon, Shag, Raven and Kestrel.

On the grassy descent is the view of Trearddur Bay welcoming us with its wide sandy bay, pretty white houses and quaint shops and cafe’s.
