The 10 best driving roads in mid Wales.

Mid Wales offers some of the most spectacular, empty tarmac in the UK. Far from the tourist traffic of Snowdonia, the Cambrian Mountains and Elan Valley hide sweeping trunk roads and technical hillside tracks that reward measured, flowing inputs.

REGION OVERVIEW

The heart of the Cambrian Mountains

The roads here are characterized by their openness. You get long sightlines across moorland, punctuated by deep river valleys and sudden, technical ascents. The main trunk routes are astonishingly well-sighted, allowing a confident rhythm without ever needing to press the car too hard, while the minor B-roads ask for extreme precision on broken surfaces.

B4574 · Cwmystwyth · Expert
Mixed widthVaried surface

Pwll-Peiran Bridge (B4574)

A fiercely technical, highly concentrated sequence of corners cutting through the valley. With an extreme curve density and unpredictable grip levels, it punishes careless inputs and demands complete focus on line-choice.

The descent past the Pwllpeiran Upland Research Centre is narrower than it looks and hides deep potholes on the inside line.

B4518 · Llanidloes · Spirited
Mixed widthVaried surface

Bwlch y Gle Dam (B4518)

Winding its way alongside the Clywedog reservoir, the B4518 is a lesson in managing elevation and camber. The road rises and falls dramatically, with corners that tighten unexpectedly, asking for patience on turn-in.

The viewpoint near the Bwlch-y-Gle dam gets busy with walkers by midday, so early morning runs are best.

B4343 · Tregaron · Spirited
Mixed widthVaried surface

Heolfryn (B4343)

Following the western edge of the Cambrian Mountains, this secondary route narrows frequently, alternating between flowing dual-track and tighter, single-track sections. The varied width and unpredictable surface demand constant attention and precise placement.

Sheep frequently wander onto the unfenced sections along the moorland stretch.

A4120 · Aberystwyth · Spirited
Dual-trackVaried surface

Penparcau Road (A4120)

A key artery heading into Aberystwyth, blending faster dual-track sections with tighter, technical turns. The varied surface quality keeps you engaged, requiring small steering corrections and a relaxed grip on the wheel.

Morning traffic heading into Aberystwyth means this is best driven as the sun goes down.

A488 · Craven Arms · Easy
Dual-trackSmooth surface

Colstey Bank (A488)

A long, flowing ribbon of tarmac that winds its way towards the English border. The relatively low curve density means the bends are predominantly long sweepers, making it an excellent road for GT cars.

The tree-lined sections north of Craven Arms create dappled light that can make reading the road surface tricky on a sunny afternoon.

Dual-trackSmooth surface

Brecon Road (B4520)

This route climbs steadily over the Mynydd Eppynt, offering a brilliant combination of wide, open moorland and nicely strung-together left-right sequences. It requires careful reading of the road surface as the elevation changes.

The cattle grids near the summit can be incredibly slippery when wet.

Dual-trackSmooth surface

Terrace Road (A493)

Tracing the edge of the coast, this road blends estuarine views with technical, flowing tarmac. The corners here follow the natural contours of the rock faces, demanding respect for the changing camber.

Keep an eye out for oncoming coaches taking a wide line around the tighter bends during the summer months.

A483 · Newtown · Easy
Dual-trackSmooth surface

Dolfor Road (A483)

A beautifully sighted trunk road climbing south from Newtown. The ascent is wide and forgiving, with sweeping radii that let the car settle nicely through the suspension.

The long climb out of Dolfor holds moisture under the trees long after the exposed sections have dried.

Dual-trackSmooth surface

Treherbert Street (A482)

An expertly surfaced primary road that winds heavily through the valley. It features a satisfying mix of sweeping bends and long straights, allowing for smooth, continuous progress without the fatigue of constant gear changes.

Watch for slow-moving agricultural traffic near the Lampeter end, especially on weekday mornings.

A44 · Llanidloes · Easy
Dual-trackSmooth surface

Pont Rhydlydan (A44)

Running west out of the Wye Valley, this stretch of the A44 is a masterclass in flowing tarmac. The surface is smooth and the corners open up generously, offering excellent visibility across the moorland. It rewards drivers who can maintain a constant, measured rhythm rather than aggressive braking.

The lay-by near the Sweet Lamb rally complex is a good place to pull over and let faster local traffic pass.
