The Finest Mountain Challenge in Wales

To complete the Welsh 3000s you need to stand on top of all 15 mountains in Wales over 3,000 ft – happily, they’re all clustered around the Snowdonia mountain range. The peaks themselves cover around 26 miles, and the walk in and out takes it to around 31 miles (50 km).

With nearly 4,000 m of height gain – like walking up and down Ben Nevis three times – and several sections of grade 1 scrambling, including the famous Crib Goch ridge and Tryfan, this is a challenge for very fit hill walkers and runners who are comfortable on rough, exposed ground.
