Caer Y Twr
History, sea views, and wildlife
Looking out from the top of Holyhead Mountain is Caer y Twr, an Iron Age hillfort settlement.
Don’t let the name put you off though - this 'mountain' is only 220m high and isn't as daunting as it may appear. We'd recommend wearing comfy shoes and clothes to climb it.
The highest point in Anglesey, the views are truly fantastic. If you visit on a clear day, you may be able to see all the way over to the Wicklow Mountains in Ireland.
Once you’ve reached the summit
Take in the breathtaking views before heading over to get a better look at Caer Y Twr. Now, mostly rubble, the outlines of walls can still be made out.
During an excavation, there was actually evidence of the footings of a Roman tower here, with the stones believed to date all the way back to between the 2nd and 4th centuries.
It was believed to once have been either a watchtower or lighthouse, but when you get there, we’re sure you’ll agree it would be the perfect place for either, with views spanning miles!
Looking at the remains, it’s incredible to imagine what once happened here all those years ago.
Time for a bit of wildlife watching too?
As well as the incredible views and wealth of history, you’ll also enjoy watching the wildlife on your visit as a lot of birds nest along the cliff faces near South Stack Lighthouse.
Look out for Atlantic puffins as well as grey seals offshore in the summer - you really get it all on a trip to Caer Y Twr.
Bring a drink and some snacks and find a spot on your walk to sit down, relax and take in the views.
On your walk back down the mountain, be sure to keep looking out for more historic remains.
On the west side, you'll find the remnants of prehistoric dry-stone walls for huts that may have been used around the same time.
The end of a great day exploring
A ten-minute drive from the bottom of the mountain is The Harbour Front Bistro, which features stunning sea views - the perfect place for a treat after a day exploring the area.
We're sure your time visiting Caer Y Twr will give you plenty to talk about with your loved ones.
