The best places to visit near Cardiff are Castell Coch, Tinkinswood Burial Chamber, Flat Holm Isolation Hospital, East Orchard Castle, Llantwit Major Beach, Pistyll Goleu, Tresilian Bay Beach and Berw-ddu Waterfall.
Cardiff sits on the Welsh coast where the Bristol Channel meets the green countryside of the Vale of Glamorgan, with hills, heritage coast and even an island all within reach. Head north and Castell Coch crowns its beech woods above Tongwynlais like something from a fairy tale.
West into the Vale lie the ancient stones of Tinkinswood burial chamber and, further on, the overgrown ruin of East Orchard Castle near St Athan. Out in the channel, a boat carries you to the derelict isolation hospital on Flat Holm.
Along the Glamorgan Heritage Coast, two beaches reward the drive: Llantwit Major with its rock pools and cliffs, and the cave-backed cove of Tresilian Bay. Turn inland to the valleys and you will find two waterfalls, the mossy Pistyll Goleu near Llanwonno and the rain-fed Berw-ddu above Aberdare.
Castles, tombs, beaches, an island and hidden falls all await. Here are eight places to visit near Cardiff.
Castell Coch

Explore Castell Coch Just north of the city above Tongwynlais, Castell Coch rises out of steep beech woodland, its three round towers capped with tall, pointed conical roofs giving it the look of a storybook castle among the trees. The Victorian architect William Burges rebuilt it from 1868 for the third Marquess of Bute, raising it on the remains of a much older medieval castle.
Inside, the painted drawing room and banqueting hall keep the richly decorated scheme he designed. Close to Cardiff and easily reached, it is one of the more enchanting places on the city's doorstep, especially with the woods in leaf.
Tinkinswood Burial Chamber

Visit Tinkinswood Burial Chamber A few miles west in the Vale of Glamorgan, near St Nicholas, Tinkinswood is a Neolithic burial chamber whose great feature is an enormous capstone, one of the largest in Britain: a single slab weighing around forty tons resting on upright stones, over a chamber where the bones of dozens of people were found. Raised around six thousand years ago, it would once have been covered by a long earthen mound, whose outline still shows.
It is a free, open site cared for by Cadw, reached on a short walk across a field, with the smaller St Lythans tomb close by.
Flat Holm Isolation Hospital

Discover Flat Holm Isolation Hospital Out on Flat Holm, a small island in the Bristol Channel off Cardiff, stands a ruined Victorian isolation hospital built in the 1890s to hold cholera cases arriving by ship. It had two wards and a nurse's room, closed in the 1930s and has stood derelict since, though work has begun to stabilise and re-roof it.
The island also carries a lighthouse, a foghorn station and old Victorian gun batteries, and it is now a nature reserve reached by boat with day trips in season. A crossing to this windswept outpost makes for a memorable outing from the city.
East Orchard Castle

Find East Orchard Castle Deeper into the Vale of Glamorgan near St Athan, East Orchard Castle is the ruin of a medieval manor house standing on low ground above the River Thaw. Fragments survive of a large hall block, with windows and fireplaces still visible, along with a long chapel, a barn and a well-preserved stone dovecote.
It was held by the Berkerolles family and later the Stradlings, and fell out of use in the eighteenth century. Sitting on private farmland, it is an obscure and little-visited ruin, the kind of quiet, overlooked spot that rewards those who like their history off the beaten track.
Llantwit Major Beach

Visit Llantwit Major Beach Over on the Glamorgan Heritage Coast, Llantwit Major Beach lies at the mouth of the valley of Cwm Col-huw, serving the town of Llantwit Major in the Vale of Glamorgan. At low tide there is sand and plenty of rock pools, all set below tall cliffs of layered limestone and shale.
A cliff-top nature reserve runs west along the coast, and the beach draws families and surfers alike. There is a car park, a cafe and toilets, and dogs are welcome through the winter months, making it an easy and rewarding coastal day out from Cardiff.
Pistyll Goleu

See Pistyll Goleu North into the hills of Rhondda Cynon Taf, Pistyll Goleu is a small, pretty waterfall in St Gwynno's Forest near Llanwonno, where the Sychnant stream drops over a face of Pennant sandstone. It is a tucked-away, lesser-known spot reached on a short walk of about ten minutes from the roadside, and is often taken in on a longer waterfall walk around Llanwonno.
Photographers are drawn to its mossy, wooded setting. There are no facilities, so it is one for a simple ramble, but its quiet green surroundings make the modest journey from Cardiff feel well worthwhile.
Tresilian Bay Beach

Tresilian Bay Beach Local legend has couples tossing pebbles up at the natural rock arch inside the cove's great cave, a courtship ritual bound to the place. The cave sits at the back of a quiet spread of pebble and rock on the Glamorgan Heritage Coast, folded between Llantwit Major and St Donat's, where limestone cliffs riddled with hollows rise behind the beach and a stream runs down the valley to the sea.
There are no facilities on the sand, and most people walk in along the clifftops from the car park at Llantwit Major. Come prepared, and the solitude is the payoff.
Berw-ddu Waterfall

Find Berw-ddu Waterfall Further north still, a day-trip to the head of the Dare Valley west of Aberdare, Berw-ddu is a hillside waterfall below the cliffs of Tarren y Bwllfa, its Welsh name meaning roughly 'black rapids'. It runs off the hillside and can be reached from the walks in Dare Valley Country Park, but it is an on-and-off fall that needs a good spell of rain to flow and can be nearly dry otherwise.
It is a lightly documented local feature rather than a mapped landmark, so time your visit for after wet weather to catch it at its best.
