Cycling routes in Wales

There are route maps and further information on cycling routes in Wales on the Sustrans Cymru website.

Short Routes

Top Road Cycling Routes in the Brecon Beacons

The following are a few suggestions taken from the Brecon Beacons tourism website. If you are looking for some inspiration for your next cycling adventure, then look no further.

These are quite short rides (1 to 2 hours), and take in some of the best scenery and quietest roads. You could always string a couple of them together for a longer ride…. You will need the OS map to work out the exact route, but here are some basic directions:

1. Llangorse Loop 30km

Leave Brecon at the roundabout by the Leisure Centre, take route 8 to T junction, then right into Groesfford, turn left towards Llangorse on the B road, but at the top of the hill turn right to Talyllyn – lovely views to R of the Beacons, and soon Llangorse lake is seen on the left.  At T junction turn R to Pennorth, and at the end left to Llangasty.  More views here and lovely downhill past Treberfydd.  Turn L at sign to Cathedine, and pass pretty cottages until you climb steeply to the road coming from Bwlch.  Turn left here and swoop along the undulations, into Llangorse (choice of 2 pubs if you are thirsty but our favourite is the Castle Inn) then after the pubs take the left to Llanfihangel, and a gentle climb back to the top of the hill you first climbed.  Flat out down the hill to Groesfford and left at the bottom, then turn right just after the underpass to return to town along the canal.

2.  Mynydd Meander 25km

Leave Brecon through Llanfaes towards Cardiff, and at the roundabout take the 3rd exit past the B&M store and Livestock market.  Climb gently for 5 km to cattle grid (Strava segment) then as you crest the top enjoy fantastic mountain views to your left. Enjoy the rolling narrow road for 9 or 10 km now until you reach a t-junction with the A4215.  Turn left and make the fast and easy descent to the main A470 just south of Libanus.  Cross the A road (slightly right/left) and take the small lane by the National Trust sign.  After a row of white cottages turn left and head back towards Brecon on tiny lanes with hedges thick with birds and wildflowers. There are several options here, best to keep R at the first junction, and then just follow your nose.  You will end up back in Llanfaes where you turn R back into town.

3. Aberyscir Adventure – 25 km

This time take the Cradoc road, climbing out of town for about 3km and turn left at Cradoc dropping down to Aberyscir and carry on towards Aberbran.  Just before Aberbran turn R signposted to Soar and start the first of 5 short climbs on this circuit. Pass some lovely woodland then drop down to Soar and turn right after you have passed all the houses. Start the next climb then as it flattens off and goes round to the left, turn right and climb again.  More nice woodland here, then drop into a stream valley and steeply up the other side. It feels quite remote now, as you climb again on seldom used lanes with grass growing up the middle. Eventually the road swings R and flattens momentarily.  There is still a bit more climbing after you pass a farm with sheepdogs on the left, but soon you emerge on to Aberyscir common, with massive views and a lovely descent back down to the village of Aberyscir where you turn left and rejoin the road from Cradoc. A few metres of easy climbing and then downhill all the way back to town.

4. Lunch at the Mill – 33 km

Start the same as route 1, this time follow route 8 all the way to Talgarth.  This is a hilly one with a few steep climbs, but lovely narrow lanes and very little traffic.

Lovely views when you top out at Penyrallt before the descent to Llanfilo.  When you reach Talgarth just head into the centre and you will find the mill near the Bridge Inn.  The Bakers Table cafe does brilliant light lunches and cakes. The return journey has a few options, none as hilly as the outbound route.  The shortest return is back the same way to the turn off from the B4560, but turn left almost immediately after this turn, and follow the very tiny lane via Tredwstan and Glyndwr, back to Llanfihangel.  From here it is a gentle climb back towards Brecon, and a fast descent to Groessford, where you can turn left and return via the canal tow path, or right back to route 8 where it ducks under the A470.

For a longer ride, stay on the B4560 to Llangorse and continue to Bwlch.  Turn left through Bwlch and right to Llangynidr on the bend coming down the hill.  (Take care as cars come fast round this bend) Down the hill to cross the Usk at Llangynidr on a lovely old bridge, then right to Talybont on Usk, and tea and cake at the Post Office if it is open.  Return to Brecon on the B road, or along the canal path.

Long Routes

Long Distance Cycle Touring Routes in the Brecon Beacons National Park – The Taff Trail and Lôn Las Cymru

Two long-distance National Cycle Routes cross the Brecon Beacons National Park, the Taff Trail and Lôn Las Cymru. Whether you’re planning a ride lasting just a couple of days or setting out on a journey of 300 miles or more, our Park is a convenient and scenic place to start or finish.  

National Cycle Route 8, The Taff Trail

Distance: 88km / 55 miles

The Taff Trail leads from Cardiff to Merthyr Tydfil, Talybont Reservoir and Brecon.

It’s a mainly traffic-free route that takes in the sights of Wales’ vibrant capital before heading to the cradle of the Industrial Revolution and ending in the beautiful Brecon Beacons National Park.

It starts in Cardiff Bay, home to some fantastic attractions such as the Doctor Who Experience. Just a short ride away, you’re transported from cosmopolitan Cardiff to rural heaven. Cycle eight relatively gentle miles along a disused railway line that follows the Taff corridor, to a region of crashing weirs rich with wildlife, impressive mountain backdrops and the picturesque Castell Coch perched on the mountainside.

On the trail, there are plenty of pretty places to stop and picnic before arriving at the industrial heritage town of Pontypridd. Here you will find a museum, a historic old bridge and the tranquil Ynysangharad War Memorial Park.

Back on the trail, head for Merthyr Tydfil, a town built on iron and coal, and home to the magnificent Cyfarthfa Castle. Visit the Castle’s museum and art gallery before climbing steadily up the Torpantau Pass where you’ll discover the old Merthyr Railway. Drop into the pretty vale of the Usk, close to the small village of Talybont-on-Usk. Then pick up the Brecon and Monmouthshire Canal at Brynich Lock and follow the old towpath into the centre of Brecon.

The surfaces are good throughout and there are plenty of places to stay along the way if you don’t fancy doing the whole thing in one day. Using Beacons Bus you can catch the bus to Brecon with your bike following on the trailer and then cycle back to Cardiff.

From Brecon, it’s possible to continue east on quiet roads, passing through Talgarth, Felindre and finally Glasbury, where you can join route 42 (Lôn Las Cymru) on the banks of the River Wye.

Barney and I have done this lovely route a few times travelling in the opposite direction, starting off in Brecon and ending up in Cardiff before arranging for Big Mike Taxis to come and pick us and the bikes up and bring us home.

National Cycle Route 42, Lôn Las Cymru

Distance: 400km / 250 miles

Lôn Las Cymru takes cyclists north from Chepstow to the Brecon Beacons National Park, then northwest across Wales to Holyhead.

Starting at Chepstow, on the banks of the River Severn, Lôn Las Cymru enters our National Park near the bustling market town of Abergavenny, which makes an ideal stopover before the steady climb up into the magnificent Black Mountains.

Leaving the River Usk behind, the trail follows delightful quiet country lanes north into the beautiful Vale of Ewyas, where it passes close to the atmospheric ruins of Llanthony Priory, much loved by artists including Turner.

More quiet lanes lead north to the tiny hamlet of Capel-y-Ffin, where the way climbs out onto open hillsides for the final push up to the spectacular 542m Gospel Pass, with marvellous views over the lowlands of the Wye Valley. From here, the trail drops sweetly into the Valley. It links with National Cycle Route 8 at Glasbury, on the banks of the mighty River Wye itself.

Mountain Biking

Stay Safe when Cycling and Mountain Biking in the Brecon Beacons National Park

To get the most out of your time on two wheels in the Brecon Beacons National Park, we recommend that you follow our top tips for safety and good practice.

Take care
  • Always wear a helmet
  • Ride within your capabilities and skills and allow plenty of time for your ride
  • Before setting out, ensure your bike is safe by checking tyres, brakes and gears
  • Tell someone where you are going and what time you intend to return.
  • Take the appropriate OS map, compass, basic first aid kit, food and money
  • Always carry a basic tool kit: a cycling specific multi-tool is best, but if not you will need 4mm, 5mm and 6mm Allen keys, small flat head and Phillips screwdrivers
  • Also make sure you carry a pump, tyre levers, puncture repair kit and some spare inner tubes – it is easier to replace a tube than to fix a puncture
  • Make sure you are prepared for all weather conditions by wearing several layers of clothing that can be adjusted
  • Take a lightweight waterproof jacket, even in fine weather
  • Padded cycling shorts can be worn under leggings in cold conditions
 Right to ride
  • In the UK, the only places where you can legally ride off-road are byways, bridleways, National Cycle Network routes ( and designated trails on private land such as forests, mountain bike centres and the banks of reservoirs.
  • Cyclists and mountain bikers must give way to horses, riders and walkers on bridleways, towpaths and other footpaths. 
Code of conduct
  • Many different people live in the Brecon Beacons National Park or come here to enjoy all sorts of pastimes. Please be considerate and courteous to all those you meet en route. It’s particularly important to slow down and give way to pedestrians. The same goes for to horse riders: failure to do so can result in horses being terrified, bolting and the rider being seriously injured. Also, bear in mind that the Brecon Beacons is a National Park and that we all have a duty to conserve the natural beauty of this special place.
    • Give way to pedestrians and horse riders
    • On public roads, respect the rules of the road
    • Don’t interfere with wildlife, plants or trees
    • Keep to published routes
    • Always leave gates as you find them
    • Take rubbish with you
    • Don’t light fires
    • Keep away from Forestry operations
    • Expect the unexpected
    • Avoid back wheel skids which can start erosion
    • Slow down when approaching and travelling through farmyards
