Lôn Las Cymru: A really wild ride

Lôn Las Cymru runs for over 250 miles down the whole length of Wales from Holyhead to Chepstow or Cardiff. Taking in three mountain ranges, it’s one of the toughest of all the long distance routes on the National Cycle Network. But don’t let that stop you - the rewards are more than worth it, offering some of the most dramatic scenery in the British Isles. From the rural lanes of Anglesey and the woodlands of Coed-y-Brenin Forest, to the valley of the River Wye and the panoramic views through the Black Mountains, this route really has it all.

    The Mawddach Estuary is stunningly atmospheric, nestled in the foothills of Cadair Idris. There are two fantastic RSPB reserves in the area. Arthog Bog is virtually on the Lon Las Cymru route and in summer is home to colourful displays of wild flowers and lots of wildlife. Coed Garth Gell is a short walk away and provides amazing views out over the estuary. A fantastic woodland and heathland nature reserve, it incorporates the route of an old gold mining track and you can still spot abandoned gold mines.

    Gigrin offers visitors the chance to view Red Kites in their natural habitat. Each day, hundreds of red kites descend on the centre and there are hides so you can get really close to the action. Seeing these graceful birds of prey in large numbers, with their unmistakable angled wings and forked tail, is truly unmissable. Gigrin is also a Red Kite Rehabilitation Centre which helps kites that have fallen ill or been injured.

    The Lôn Las Cymru route passes the Talybont Reservoir, the largest man-made lake in the Brecon Beacons. Much of the reservoir’s water begins its journey high up in the mountains at the head of the Talybont Valley. At Blaen-y-Glyn, you’ll find some of the most spectacular waterfalls in the country, which are easily accessible by foot from the reservoir.
