Best Places to Visit in Flintshire & Wrexham

The best places to visit in Flintshire & Wrexham are Plas Power Park, Castell y Fflint, Plaspower Waterfall and Pontcysyllte Aqueduct.
Flintshire and Wrexham run along the Dee from the estuary to the hills above Llangollen, and their finest places mix engineering, castles and quiet woodland. The great sight is the Pontcysyllte Aqueduct, Thomas Telford's cast-iron canal trough carried high across the Dee valley on tall stone piers, the highest canal aqueduct in the world and now a World Heritage Site.
On the estuary at Flint, the ruined castle keeps its unusual detached great tower, the first of the castles Edward I raised in his conquest of Wales. Inland, the ancient woodland of Plas Power in the Clywedog valley threads its riverside paths past a stretch of Offa's Dyke, with a photogenic cascade tumbling over the Clywedog within the same woods.
All four lie within easy reach of Wrexham and the Dee. Some are grand feats of building, others gentle river walks.
Here are four places to visit across Flintshire and Wrexham.
Plas Power Park

Plas Power Woods is an ancient woodland estate park in the Clywedog valley just west of Wrexham, looked after by the Woodland Trust. The River Clywedog runs through it over a weir and stepping stones, with kingfishers along the water, and a well-preserved stretch of Offa's Dyke, the great earthwork boundary raised in the eighth century, runs through the trees, marked by a carved figure of King Offa.
Waymarked paths thread the woods, part of the Clywedog Valley Trail, with the remains of old tramways and mills from the area's ironworking days. The nearest parking and visitor centre are at Nant Mill close by.
Castell y Fflint

Flint Castle sits on a low rise beside the tidal Dee estuary at the edge of Flint town. Its most unusual feature is the large round great tower at one corner, cut off from the rest of the castle by its own moat, a keep set apart like a small fort of its own.
Three further corner towers and lengths of curtain wall stand in ruin around the square plan. Begun in 1277, it was the first of the castles Edward I built during his conquest of Wales.
Plaspower Waterfall

Plaspower Waterfall is a cascade on the River Clywedog within Plas Power Woods, the Woodland Trust estate just west of Wrexham, reached on the riverside walk through the trees. The water tumbles over a rocky step in the river, part weir and part natural fall, into pools where children paddle on warm days, a photogenic spot along the Clywedog Valley Trail.
It lies close to the weir and stepping stones on the same stretch of river, in quiet woodland, with the nearest parking at Nant Mill nearby.
Pontcysyllte Aqueduct

The Pontcysyllte Aqueduct carries the Llangollen Canal high across the valley of the River Dee near Llangollen, a cast-iron trough on tall stone piers and the highest canal aqueduct in the world. It stands about thirty-eight metres above the river and runs some three hundred metres on nineteen arches, the narrow iron channel carrying boats across with a towpath on one side and an open drop on the other.
It was built between 1795 and 1805 by Thomas Telford and William Jessop, and now forms part of a World Heritage Site. Visitors walk the towpath, take boat trips across or steer their own narrowboats over the valley.
FAQs
Can you walk across the Pontcysyllte Aqueduct?
Yes, a towpath runs along one side of the cast-iron trough, so walkers can cross the Dee valley high on the Pontcysyllte Aqueduct, with an open drop on the other side. You can also take a boat trip across or steer your own narrowboat over, on the highest canal aqueduct in the world, part of a World Heritage Site.
What is unusual about Flint Castle?
Its great tower stands at one corner, cut off from the rest of the castle by its own moat, a keep set apart almost like a small fort of its own, which is rare among British castles. Begun in 1277 beside the Dee estuary, it was the first of the castles Edward I built during his conquest of Wales.
Where can you go for a quiet walk in Flintshire and Wrexham?
Plas Power Woods, an ancient woodland in the Clywedog valley just west of Wrexham, is the best place for a quiet walk in Flintshire and Wrexham, with waymarked riverside paths past a weir, stepping stones and a stretch of Offa's Dyke. The Plaspower waterfall tumbles over the river in the same woods, and parking is at Nant Mill nearby.
Conclusion
Flintshire and Wrexham gather their best places along the Dee, from estuary to hills. The Pontcysyllte Aqueduct is the great sight, Telford's iron trough carried high across the valley on its stone piers, the highest canal aqueduct in the world.
At Flint, the ruined castle keeps its detached great tower, the first Edward I raised in Wales. Inland, the ancient woodland of Plas Power threads its riverside paths past Offa's Dyke, with a photogenic cascade tumbling over the Clywedog in the same woods.
From soaring aqueduct to quiet river walk, these are the places to seek out across Flintshire and Wrexham.
