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. A Caernarfon Castle Caernarfon Castle, North Wales King Edward I built Caernarfon Castle, one of the most impressive Welsh castles. Now a World Heritage Site, the castle has unusual polygonal towers, two of which house the Royal Welch Fusiliers Museum. You can walk a complete circuit of the castle walls, offering wonderful views of the Menai Strait and Snowdonia in the distance. B Portmeirion, Gwynedd Portmeirion, Snowdonia by technodean2000 Set on its own private peninsula on a rugged clifftop overlooking Cardigan Bay, the unique Mediterranean inspired buildings that make up Portmeiron are surrounded by tropical woodland and stunning coastline. Visit in early September and experience the truly brilliant ‘Festival No.6’ which is set in this fantastical location - a unique, magical feast for the senses! C Mawddach Estuary Cyclists near Barmouth Bridge on the Lôn Las Cymru cycle route North Wales by Sustrans 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. D Gigrin Farm, Rhayader Red kites 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. E Blaen-y-Glyn Waterfalls Blaen-y-Glyn Waterfall in the Brecon Beacons by Paula J James 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. Find out more about cycling in Wales Enjoy this?
