The coastal path goes around the headland above South Stack lighthouse, but you can deviate off the path, head down the steps, and if you have a ticket, cross the bridge onto the island.
Here it is, part of the way down the 400 or so steps down to the bridge -
It was during the early part of a flood tide, and about 300 metres north of South Stack there was a cracking tide race out in the open water.
Under the bridge there was quite a strong current - you`d have a job paddling through there against the current. It`s a pity it is so confined, as there wouldn`t really be enough room to play there.
From the island you get a good view of the rather weird rock formations on the mainland side of the narrows.
Again, from the island you get a good view looking down the coast towards and across Abraham`s Bosom to the Penrhyn Mawr peninsula.
And a cracking view across Gogarth Bay to North Stack.
Here`s the sea kayak bit - looking down from the top of the lighthouse at some paddlers on their way to Holyhead.
It`s not surprising that Porth Dafarch to Holyhead is one of the classic sea kayak trips around Anglesey - it is a fabulous bit of coastline whether you are on land or on the sea, and the tidal currents and tide races certainly give it an extra dimension.
It is one of the most challenging bits of the Anglesey coast for sea kayaking, and not to be undertaken lightly.
