The 10 best driving roads in North Wales.

North Wales is defined by its gradients and the slate-grey sky that hangs over them. From the high mountain passes of Snowdonia to the sweeping moorland runs that dissect the national park, the region offers some of the most rewarding tarmac in the UK. This is our definitive guide to the ten roads that matter.

REGION OVERVIEW

Driving in North Wales

The landscape here dictates the road. While Scotland relies on vast, open glens, the Welsh topography forces routes to cling to valleys, weave through deep forestry, and scramble over harsh moorland. The result is a network that heavily favours the precise driver over the merely fast one. Expect sharp camber changes, sudden drops in visibility, and sheep grazing closer to the apex than you might like. To drive well here is to read the environment as much as the surface.

Dual-trackSmooth surface

Lon Union (A4085)

Winding south towards Beddgelert, the A4085 is a fiercely tight and twisting route. Despite being dual-track, the relentless frequency of corners makes it feel much narrower. It is an intense, busy road that demands constant line-choice and immediate responses, offering little in the way of resting periods.

The road runs immediately adjacent to the Welsh Highland Railway in places, and you'll frequently encounter slow-moving tourist traffic watching the trains.

Dual-trackSmooth surface

Bryn Bella (A5)

The A5 is the historic artery through Snowdonia, and the section south of Bethesda remains an exceptional piece of highway engineering. It follows the path of least resistance through the mountains, resulting in a wide, sweeping carriageway with predictable radii. It provides an excellent, low-stress run that lets you drink in the scenery without fighting the steering wheel.

The stretch alongside Llyn Ogwen is prone to heavy spray in wet weather, drastically reducing visibility on the fastest sweepers.

Pentrefoelas Road (A543)

Making up the northern leg of the famed 'Evo Triangle', the A543 across the Denbigh Moors is defined by its sheer scale. The tarmac stretches out across the rolling heather, characterized by long straights and fast, open sweepers. It is a road that asks for patience and smoothness, rewarding drivers who understand how to balance a car through sustained arcs.

Average speed cameras are now a permanent fixture along this entire stretch, rendering it an exercise in momentum conservation rather than acceleration.

Berwyn Street (B4391)

Climbing away from Bala, the B4391 quickly gains altitude, morphing into a wide, open moorland pass. The road is incredibly generous, with long, sweeping corners and immense sightlines across the Berwyn range. It is less demanding than the tighter valley routes, offering a deeply satisfying, relaxed drive where you can simply enjoy the topography.

The summit offers uninterrupted views back towards the mountains, but is completely exposed to sudden crosswinds.

Dual-trackSmooth surface

Pont Llwyngwril (A493)

Between Rhoslefain and Fairbourne the A493 is pinned between the Cambrian Coast line on the seaward side and hills that rise steeply straight off the inland verge, so the road bends where the land does rather than where an engineer wanted it. The result is a medium-speed coastal road with a good surface and steady rhythm through Llangelynnin and Llwyngwril, then the Friog Hill section under the same rockfall-prone slopes that made the railway build itself an avalanche shelter. It rewards smooth inputs and staying on your side of the white line.

The Friog Hill to Llwyngwril stretch spent more than two years on temporary lights to 2024 while a safety fence awaited repair, and the council logged incidents when the lights failed, so expect a queue there and treat a blank head with suspicion. Crashes have also shut the road between Llwyngwril and Rhoslefain.

B5113 (Colwyn Bay)

South of Bryn-y-maen and its 'Cathedral of the Hills' church, the B5113 climbs onto the broad ridge that runs parallel to the Conwy Valley and stays up there for most of these eight miles, on the western edge of the Denbigh Moors. The surface is good and the road is a full two lanes, so the steady run of corners can be treated as a rhythm exercise; the Carneddau sit across the valley one way, the Great Orme and the sea the other.

There is barely a hamlet between the B5381 crossroads at Glasfryn and the descent towards Llanrwst; a small lay-by below Mwdwl Eithin's trig point is the one obvious place to stop, and the sheep on the plateau spook easily.

Pont Elwy (A544)

The A544 runs eight miles from the A543 at Bylchau, on the high ground above Denbigh, down the Aled valley through Llansannan and on to the Elwy at Llanfair Talhaiarn. It is a two-lane A-road with a good surface and curvature well above its class: crests and quick direction changes on the upper section, then a valley road with steep sides closing in around Llansannan, where the straight run through the village to the river bridge is a 19th-century realignment. It rewards reading the road two corners ahead; the sightlines come and go with the valley.

The road ends on the Elwy floodplain at Llanfair Talhaiarn, crossing the river on the newer bridge a hundred yards above the old three-arch one. Be down to village pace before you see it. The Llansannan to Bylchau section has had its collision closures.

Stryd Gwynant (A498)

From the 277-metre summit at Pen-y-Gwryd the A498 loses 600 feet in about two miles, and does it on a narrow, twisting alignment where anything wide struggles to pass. This is the technical part of the road, and the part that asks for patience. Below that it settles along the southern shore of Llyn Gwynant and past Llyn Dinas toward Beddgelert, alternating open lakeside stretches with tighter, walled and tree-lined sections. It rewards braking-zone judgement and smooth inputs on the descent rather than pace.

The lay-by above Llyn Gwynant is one of the most photographed views in Eryri, so expect cars braking hard into it, and the Watkin Path leaves the road at Bethania, so walkers cross there. Beddgelert finishes with a right-angled bend over the bridge that lorries are told to avoid.

Llandrillo Road (B4401)

The B4401 is the quiet south-bank alternative to the A494 along the upper Dee, leaving the main road just outside Bala and running nine miles through Llandderfel, Llandrillo and Cynwyd towards Corwen. It stays on the valley floor with the Berwyn rising to the south, so the corners come from following the river rather than from gradient, and the road rewards reading the hedgerows for the next bend. Two-lane throughout, with village limits breaking the rhythm at regular intervals.

Ifor Williams builds its trailers at Cynwyd, so expect the odd flatbed on the eastern end. The road took weeks of roadworks closures with a long diversion in spring 2026, and the Llandderfel to Llandrillo stretch has a serious-collision history, so it is not one to hurry.

Llanberis Pass (A4086)

Built in the 1830s to get ore down from the Snowdon mines, the A4086 climbs from Nant Peris to Pen-y-Pass at 359 m in under five kilometres, averaging 5% with a short pitch over 10%. The valley is straight and steep-sided, so the road's interest is in its camber changes and the way dry-stone walls and roadside boulders trim your sightline rather than in any great number of corners. It rewards smooth inputs and a lane-centred line; the Cromlech Boulders that crowd the carriageway are there because locals fought off a 1973 widening scheme.

Pen-y-Pass has 68 pre-booked spaces and the verge is a clearway that gets towed, so the pass itself stays clearer than you'd think; the queue you meet is for the Nant Peris park-and-ride, three miles below.
