Snowdonia 10 Peak Challenge
An epic one-day mountain journey over ten summits in the Carneddau – the most remote mountain range in Wales and England – from the Ogwen Valley to the coast at Llanfairfechan. Rocky ridges, high summits, mountain lakes and rolling hills.
Fully guided and supported. The perfect stepping stone to the Welsh 3000s.
“Thanks to everyone for a wonderful day out. Team morale was brilliant and really helped push us onwards and upwards! Excellent service from your team who looked after all of us, especially those of us who struggled!”

Ten Summits, Ogwen to the Sea
The Snowdonia 10 Peak Challenge climbs many of the highest mountains in Wales and crosses the remote Carneddau, starting in the Ogwen Valley and finishing at the coast. The route is 25 km long with 1,200 m of ascent and descent – and it isn’t to be underestimated.
It’s easier and less technical than the Welsh 3000s, which makes it a great test of fitness and a brilliant stepping stone. For bigger teams, we also run a 42 km version that adds the Snowdon range, and a two-day option.
