The hidden gems near Bangor are Plas Cadnant Hidden Gardens, Glan Faenol, Bryn Celli Ddu Burial Chamber, Castell Aberlleiniog, Penmon Dovecot, Penmon Point, Dinorwic Quarry and Cwm Idwal National Nature Reserve.
Bangor sits at the edge of the Menai Strait, with Anglesey across the water on one side and the mountains of Snowdonia rising on the other, so hidden gems lie in every direction. Cross the strait to Anglesey and you can wander the restored Regency gardens of Plas Cadnant near Menai Bridge, stoop into the ancient tomb of Bryn Celli Ddu, or head north-east to the little castle of Castell Aberlleiniog and the old stone dovecote and lighthouse-watching headland at Penmon.
Closer to town, Glan Faenol offers a quiet shoreline walk along the strait with views back across the water. Turn inland and south instead and the land climbs fast: the vast slate terraces of Dinorwic Quarry loom above Llanberis, while further into Snowdonia the glacial bowl of Cwm Idwal cradles its dark lake beneath a ring of cliffs.
It is a rare spread of gardens, ancient stones, industry and mountains, all close at hand. Here are eight hidden gems to seek out near Bangor.

Wander Plas Cadnant Hidden Gardens Just across the strait near Menai Bridge, Plas Cadnant is a set of restored Regency gardens laid out in the early nineteenth century and coaxed back to life over recent decades after long neglect. You can wander a curving walled garden with a pool, a wooded valley where the little River Cadnant tumbles through a rocky gorge in a run of waterfalls, and woodland holding the ruin of an old folly.
A large collection of hydrangeas grows here, with a tea room and plant sales. The valley was badly flooded in a 2015 storm and has since been rebuilt.
Being so close to Bangor, it makes an easy outing.
Glan Faenol

Stroll along Glan Faenol A short hop from Bangor, Glan Faenol is a stretch of woodland and old parkland on the shore of the Menai Strait, part of the former Vaynol estate and now in the care of the National Trust. A waymarked walk of about a mile and a half runs through the trees and along the shore, with a bird hide and views over the water to Plas Newydd and the Snowdonia hills.
Old estate buildings and a long boundary wall still stand. It is a quiet, free place to walk, open from dawn to dusk.
Bryn Celli Ddu Burial Chamber

Step inside Bryn Celli Ddu Burial Chamber On Anglesey, Bryn Celli Ddu is a Neolithic burial tomb counted among the finest ancient monuments in Wales. A grass-covered mound holds a low stone passage leading into a chamber at its heart, built more than four thousand years ago on the site of an even older ritual circle.
You can stoop down the passage and stand inside, where a tall smooth pillar rises from the floor. The tomb is known for its solar alignment: at dawn on the longest day, the rising sun shines straight down the passage to light the inner chamber.
A carved, spiral-patterned stone found here is now in the national museum.
Castell Aberlleiniog

Climb to Castell Aberlleiniog Castell Aberlleiniog stands on a steep, ditched earth mound in woodland near Llangoed on Anglesey. On top sits a square stone enclosure with a round tower at each corner, its walls pierced by narrow slits.
The ruin has been repaired and made safe, and wooden steps climb the mound to it, with panels explaining what you see. Footpaths through the trees from the village are the only way in, a peaceful north-eastern corner of the island.
Penmon Dovecot

Penmon Dovecot Step inside and the walls climb away in tier after tier of nesting holes, hundreds of them, with a tall pillar rising at the centre that once bore a revolving ladder for reaching the highest. Built around 1600 near the eastern tip of Anglesey, this square, domed stone house with its little rooftop turret kept doves by the hundred, a ready supply of meat and eggs for the estate.
It stands beside the ruins of Penmon Priory, and entry costs nothing. Fold it into a wander round the wider site, where a priory church, a holy well and old Celtic crosses wait, with parking close at hand.
Penmon Point

Penmon Point A bell tolls across the water from the Trwyn Du lighthouse, a white tower banded in black and raised in the 1830s after a shipwreck offshore. It stands just out from Penmon Point, also known as Black Point, the rocky headland at Anglesey's south-eastern tip, gazing over a narrow sound to the humped shape of Puffin Island.
A private toll road drops down to the car park, and a small cafe waits by the shore. Come for the seabirds, the moving sea, and wide views across the Menai Strait to the Great Orme and Snowdonia beyond.
Dinorwic Quarry

Dinorwic Quarry Above Llanberis in Snowdonia, this enormous abandoned slate quarry was carved into the flank of Elidir Fawr. Terraced galleries rise in giant steps up the mountainside, littered with collapsing sheds and piles of shattered slate that have lain untouched since work stopped in 1969.
Down at the base, the old workshops now house the National Slate Museum, while hidden within the mountain itself sits a pumped-storage power station. The whole place belongs to a World Heritage Site recognising the slate landscape of north-west Wales.
It makes for a strangely moving reminder of Welsh industry.
Cwm Idwal National Nature Reserve

Cwm Idwal National Nature Reserve is a glacial bowl set high in the mountains of Snowdonia, cradling the dark waters of Llyn Idwal within a ring of cliffs. It holds the distinction of being the first national nature reserve ever declared in Wales.
A path of about three miles circles the lake from the car park at Ogwen, rising towards the great cleft in the headwall known as the Devil's Kitchen. The sheer rock walls and hanging valley pull in walkers, climbers and geologists alike, each drawn by something different.
Lace up your boots and take the loop at an unhurried pace.
FAQs
Which of these hidden gems are on Anglesey?
Several sit just across the Menai Strait from Bangor. Plas Cadnant near Menai Bridge, the tomb of Bryn Celli Ddu, Castell Aberlleiniog near Llangoed, and both Penmon Dovecot and Penmon Point at the island's eastern tip are all on Anglesey, an easy drive over the bridges.
Are there good mountain walks near Bangor?
Yes. Head inland from Bangor into Snowdonia for Cwm Idwal, a three-mile loop around Llyn Idwal beneath its cliffs, or explore the huge slate terraces of Dinorwic Quarry above Llanberis. Both give proper mountain scenery within a short drive of the city.
Do any of these places cost money to visit?
Plas Cadnant near Menai Bridge charges admission as a private garden, and Penmon Point has a toll road. Many others, including Glan Faenol, Bryn Celli Ddu and Cwm Idwal, are free to explore, though some Snowdonia car parks near Bangor charge for parking.
