Hidden Gardens Near Betws-y-Coed: Quiet Corners of Eryri and Anglesey
Why Hidden Gardens Near Betws-y-Coed Are Worth Seeking Out
Bodnant and Portmeirion draw the coach parties, and rightly so. North Wales holds plenty of hidden gardens near Betws-y-Coed too. You’ll find them behind castle walls, down hidden valleys and off quiet woodland car parks. These places reward anyone willing to look past the obvious names. Bryn Bella Guest House, on the hillside above Betws-y-Coed, makes an easy base for all four. Return each evening to wide views over the Conwy Valley, then set out again the next morning.
Gwydir Castle: Renaissance Splendour Close to Home
Gwydir Castle sits just down the valley in Llanrwst, so it’s the closest of these gardens to Bryn Bella. Sir John Wynn’s family built this Tudor courtyard house in the sixteenth century. Its Grade I listed garden still carries their stamp today. Fourteen yews here predate 1700. Three surviving Cedars of Lebanon date to around 1625, planted to mark King Charles I’s marriage. The Old Dutch Garden pairs vast clipped yews with a central fountain. In 1828, architect Sir Charles Barry laid out the Tudor Rose knot garden nearby, and peacocks have kept the lawns company ever since. Gwydir Castle usually opens Wednesday to Sunday between April and October, so check its website before you travel. It’s an easy stop on the way to or from Llanrwst.
Plas Brondanw: Clough Williams-Ellis’s Own Garden
Architect Clough Williams-Ellis inherited Plas Brondanw in 1908, at just twenty-five. By then, tenants had split the house into flats, and the garden had become allotments. He spent decades restoring both. He shaped the grounds into a series of Italianate rooms. Yew hedges enclose each one, and axial views link them, framing Cnicht, the peak locals call the Welsh Matterhorn. A 1915 folly tower gives 360 degree views across the mountains and the sea. Below it, a quarry pool feeds a dramatic cascade. The garden earned Grade I listing, one of only three in Gwynedd. Since Williams-Ellis also designed Portmeirion, a visit here shows where his ideas began. Plas Brondanw’s garden opens daily, year round, from 10am to 4pm.
Plas Cadnant: A Hidden Valley Garden on Anglesey
Cross the Menai Strait and you’ll find Plas Cadnant Hidden Gardens near Menai Bridge, spread across nearly ten acres. Three distinct areas sit side by side here. The Walled Garden curves around a still pool. The Valley Garden tumbles past three waterfalls and a running river. Meanwhile, the Upper Woodland Garden climbs past stone outcrops and the ruins of a nineteenth century folly. In 2026, Plas Cadnant opens daily from June to August, then on fewer days through September and October. That pattern suits a full day trip from Betws-y-Coed rather than a quick detour. Combine it with lunch in Menai Bridge before heading back to the quieter pace of the Conwy Valley.
Plas Tan y Bwlch: Free Woodland Gardens Above the Dwyryd
Plas Tan y Bwlch is Eryri National Park’s study centre above the Dwyryd valley, near Maentwrog. It welcomes walkers into its gardens for free. Park at the centre and follow paths into informal, largely shaded woodland gardens. Formal terraces, a water garden and a pond occupy the higher ground. Native oaks, beech, Scots pine and Irish yew grow there too, alongside species brought in from further afield. Rhododendrons and azaleas light up the grounds in spring and early summer. Afterwards, the wider Dyffryn Maentwrog area offers over 30km of connected footpaths around Llyn Mair. A short garden visit can easily grow into a longer walk.
