Rid yourself of the range anxiety and hit the road with our guide to taking an EV across the Brecon Beacons. Here's the best route and where to charge up.


With twisting and undulating roads that traverse valleys, lakes and sublime countryside, the Brecon Beacons has always been a diving mecca and beauty spot. 

Stretching 45 miles from near Llandeilo in Carmarthenshire all the way to the English border, the National Park encompasses some of the finest scenery in southern Wales. 

Cardiff to Brynamman via Merthyr Tydfil

Setting off from Cardiff with a full battery, head up on the A470 through the valleys in the direction of Merthyr Tydfil. From there, take the A465 before breaking off at Glyneath and onto the A4109, A4067 and A4068 to Brynamman. While the route skirts the edges of the Brecon Beacons national park, you get some stunning views across the rolling hills. At Brynamman, there's a number of 22kwh chargers, so it might be worth topping up before the blasting across the Beacons.  

The Black Mountain Pass

The Black Mountain Pass should be familiar to car enthusiasts. A firm favourite of the motoring media, the road has been the backdrop for many photoshoots and videos and for good reason. Twisting and turning its way through the western edge of the Brecon Beacons, the pass also features a hairpin known locally as Tro Gwcw, or ‘cuckoo turn’. Added to that, you'll be treated to views of the Tywi Valley along the way. 

Towards the end of the pass branch off northeast and head towards Trecastle. For those in need of a top-up after some spirited driving, there's a 7kwh charger on the road to Trecastle.

Trecastle to Torpantau 

Heading east from Trecastle, pick up the A40 and skirt the top of the Brecon Beacons driving towards Brecon. For those looking for a more substantial charge, Brecon has a number of 22 and 50 Kwh chargers available. Just after Brecon, take the turning for the B4558 and cut down south towards Talybont-on-usk. 

Here, enjoy the drive past Talybont Reservoir, fields, forests and hills on the way to Torpantau, once the site of the highest station on the Brecon and Merthyr Railway line.  

Torpantau to Merthyr Tydfil

From Torpantau, keep heading south past Pontsticill Reservoir where the road will eventually bring you out close to Merthyr Tydfil. With a number of 50kwh chargers available, the town is an ideal top-up point before starting the drive south, back to Cardiff, east towards Abergavenny or west in the direction of Pembrokeshire.
