The hidden gems near Swansea are Penllergare Valley Woods, Neath Abbey, Loughor Estuary, Cathole Cave, Giant's Grave, Stepping Stones, WWT Llanelli Wetland Centre and Brombil Reservoir.
Swansea sits between the sweep of the bay and the green hills behind, with the Gower peninsula on its doorstep and the old industrial valleys close at hand. Head north and you reach a restored Victorian valley of woodland, lakes and a waterfall.
To the east, towards Neath and Port Talbot, lie a grand abbey ruin and a still reservoir hidden in wooded hills above the steelworks. West and southwest, the Gower opens up: an ancient cave with rare rock art, a Neolithic burial chamber, and stepping stones that lead down to one of the loveliest bays in Wales.
Along the shore, the wide Loughor Estuary and a wetland reserve across the water in Carmarthenshire draw wading birds by the thousand. Some of these spots are a short hop from the city, others a proper afternoon out, but none are far.
Whether you prefer prehistory, wild coast or a quiet woodland walk, there is something here to suit. Here are eight hidden gems to seek out near Swansea.
Penllergare Valley Woods

Penllergare Valley Woods The man who laid this valley out, John Dillwyn Llewelyn, was a pioneer of early photography as well as a keen gardener, and an observatory once stood among his grounds on the northern edge of Swansea. His Victorian landscape spreads over a hundred hectares of woodland, with two lakes, a waterfall and some seven miles of paths tracing the River Llan.
The great house fell in the 1960s and a motorway later sliced through, yet a local trust has spent years coaxing the gardens and lakes back to life. There is a community cafe, entry is free, and the falls and water draw you in.
Neath Abbey

Explore Neath Abbey About a mile west of Neath stands this substantial ruin of a Cistercian abbey, once called the fairest abbey in all Wales and among the most impressive monastic remains in the country. You can walk the full medieval layout, along with a surviving gatehouse, and trace the later history laid over it, including a Tudor mansion built into the cloisters and eighteenth-century copper-smelting furnaces.
Founded in 1130 and dissolved in 1539 under Henry VIII, it is now a free Cadw site with a car park and level access.
Loughor Estuary

Loughor Estuary At low water the estuary drains to great flats of sand and mud fringed with salt marsh, a haunt of wading birds and wildfowl important enough to matter on an international scale. This is the tidal mouth of the River Loughor, running between the Gower peninsula to the south and Llanelli and Carmarthenshire to the north before it widens into the Burry Inlet.
Cocklers have long worked these flats from villages such as Penclawdd on the Gower shore. Grazed saltmarsh, the old Whiteford lighthouse and a national nature reserve line the edges, and the whole estuary carries several conservation designations.
Wide skies and binoculars reward a slow visit.
Cathole Cave

Find Cathole Cave Out on the Gower near Parkmill, this limestone cave sits in a steep rock face above the wooded Parc le Breos valley. A short climb from the valley floor reaches the triangular opening, with a natural rock platform outside.
Inside, an Upper Palaeolithic engraving of a deer was found on the rear wall in 2010, among the oldest rock art known in Britain. A metal grille now guards the entrance.
Giant's Grave

See the Giant's Grave Nearby in the same wooded valley stands this Neolithic chambered tomb, properly Parc Cwm long cairn or Parc le Breos, near Parkmill west of Swansea. Built around 5,800 years ago, it is a long stone mound with a central passage and pairs of side chambers, its covering earth long gone so the stonework lies exposed.
A level track of a couple of hundred metres from a small parking area reaches it. Cadw looks after it, and it is free and open.
Stepping Stones

Cross the Stepping Stones A long line of stones carries the coast path over the mouth of Pennard Pill, the stream that threads down the middle of Three Cliffs Bay on the Gower's south coast. Cross them and you reach the dunes below Pennard Castle's ruin and the trio of limestone cliffs that name the bay, one of the loveliest views in Wales.
The water is usually shallow enough to paddle, but the sands vanish quickly on a rising tide and the beach can be cut off, so keep a careful eye on the sea.
WWT Llanelli Wetland Centre

Visit WWT Llanelli Wetland Centre Across the water in Carmarthenshire, this wetland nature reserve run by the Wildfowl and Wetlands Trust sits on the Burry Inlet at Penclacwydd, east of Llanelli. Trails and boardwalks lead through lagoons, pools, reedbed and saltmarsh, with hides and observatories looking out over the estuary.
Visitors see collections of ducks, geese and swans alongside wild birds that feed on the mudflats, and there is a visitor centre with a cafe and shop. The estuary is protected for its large numbers of wintering and migrating birds.
Brombil Reservoir

Seek out Brombil Reservoir In the hills above Margam, near Port Talbot, this disused reservoir lies in a quiet wooded valley. The water sits still and dark, sometimes turning a vivid blue-green in warm weather, ringed by trees and rough hillside, with the great sprawl of the Port Talbot steelworks visible down on the coast below.
Made long ago to serve local industry, it has since fallen out of use and been left to nature. Paths loop around it, one climbing steeply to higher viewpoints over the valley and the sea, another dropping to the water's edge over stepping stones.
It is a walkers' spot, an odd, peaceful pocket of woodland and water with heavy industry as its backdrop.
